About ICP2
In 2008, WRAP published Kerbside Recycling: Indicative Costs and Performance (ICP) which
provided a systematic appraisal of the characteristics of the principal kerbside recycling
collection systems looking at both their cost and effectiveness. The outputs from that
project have been widely used.
The continued use of those outputs by Local Authorities, the development of new types of
recycling services, combined with improved knowledge around scheme performance and
costs, resulted in a need to update the project (ICP2).
The aim of the update is to produce a series of benchmark costs and standard operational
data, through service modelling, that local authorities can use when evaluating their current
recycling service and considering service changes. The resultant benchmarks are based on
the performance (yields of food and dry recycling) and cost of a modelled good practice
system operated across a range of geographical areas.
The key output from this project is the ICP2 Online Tool. The online tool takes the
operational outputs and collection costs from the ICP2 modelling and allows the user to
localise the outputs by applying their own gate fees, bulking costs, disposal costs and
material revenues to produce an overall scenario cost. The localised scenarios are displayed
in a table and a graph.
This document provides the detail behind the assumptions used in the ICP2 modelling.
2.0 KAT and ICP2
The Kerbside Analysis Tool (KAT) was developed in 2004 for modelling recycling and
residual waste collection services. It has been updated over the following 10 years to
expand the number and variety of recycling collection systems that can be covered by the
model. The most recent update was in 2012 (KATv5) and it is this version that is used in
ICP2. KAT forms just one part of the ICP2 model. The other parts include a set of yield
calculations, a sorting cost tool, and an ICP2 results model ; their interactions are shown in
Figure 1. The components are shown in white boxes and the data flows in blue.

3.0 Scenarios
In 2013/14, all mainland authorities in England operated a kerbside recycling. The schemes
in operation are categorised by three types:
 Single Stream Co-mingled (SS), operated by 50% of LAs in 2013/14
All materials are collected together in one compartment on the same vehicle and require
sorting at a MRF (Materials Recovery Facility).
 Two-stream (TS), operated by 34% of LAs
Materials are collected as two material streams, typically either fibres and containers, or
glass separate to other mixed material. At least one of the streams requires sorting at a
MRF.
 Multi-stream (MS), operated by 29% of LAs
Materials are separated by the householder or, on collection at the kerbside, into multiple
material streams. The material streams may include a selected mix of some materials,
typically cans and plastics, which are commonly separated using basic sorting facilities at the
operating depot or sold to reprocessors as a mixed commodity.
The percentages add up to more than 100% as some LAs will operate more than one
scheme type in their authority (e.g. multi-stream to kerbside properties and two-stream to
flats).
In 2013/14, 81% of authorities in England collected the 5 OPRL1 ‘widely recycled’ materials
(paper, card, cans, glass and plastic bottles) at the kerbside. 53% of authorities also
collected pots, tubs and trays (PTT). ICP2 focuses on good practice schemes therefore the
scenarios chosen collected all 6 of these materials at the kerbside.
Food waste collections have become more prevalent since the original ICP modelling and
research has shown that food waste collections are linked to high recycling rates2.

Therefore, focussing again on good practice, several scenarios included a separate food
waste collection to provide an integrated service.
Whilst garden waste collections are prevalent, the services were not included in the
scenarios due to the wide variability in service collection types offered across England and
the yield derived from them. The large variations in yield and costs are a result of
differences in collection frequency, crew size, variations in garden sizes, numbers of
properties with gardens, seasonal or year round service delivery, containment approaches
and whether services are offered free or by subscription to residents.
Table 1 lists the 18 scenarios identified for modelling. The scenario code describes the
scenario:
The above example is a fortnightly two stream collection where glass is the separate stream
to the other mixed materials (paper, card, cans, plastic bottles and PTT) and collected on a
split-back RCV. Residual waste is collected fortnightly and food waste is collected weekly
with a dedicated vehicle.

4.0 Rurality Groups
In the ICP2 tool, the user can select one of six rurality groups to display the results. The
rurality groups represent different geographical and demographic contexts and therefore
model the scenarios in areas that are more specific than just urban/rural as was the
assumption in the original ICP study.
In developing a rurality classification scheme the 2001 Defra classification of rurality was
explored to see if it could be used. This classification of local authority area types describes
areas in terms of their rurality5 (Major Urban, Large Urban, Significant Urban, Significant
Rural, Rural-50 and Rural-80). This classification was tested against the variables ‘population
density’ and ‘proportion of rural households’ (Figure 3) to establish the extent to which it
provided a clear urban-rural gradient. The analysis showed that a number of authorities
classified as ‘Major Urban’ and ‘Large Urban’ had population densities, or proportions of
households classified as rural, that were similar to local authorities classed as ‘Significant
Rural’. This over-lapping classification meant that it was not ideal for use in ICP2.

A simpler approach was developed where the unitary and collection authorities were split
into three groups based on the percentage of rural households (Figure 4). This classification
gave a clearer demarcation between urban authorities and those intermediate authorities
with significant rural housing. Three geographical contexts were chosen and defined as:
 Predominantly urban (less than 1.5% of households defined as ‘rural’)
 Mixed urban and rural (more than 1.5% but less than 33% defined as rural)
 Predominantly rural (more than 33% of households defined as rural)

Less than 1.5% rural
>1.5, less than 33% rural
>33% rural
WRAP’s work on analysing factors that affect kerbside recycling performance6 identified
deprivation as a key influence. As the relative performance of a scheme has a bearing on
workload for crews (proportion of households setting out containers and the quantity of
materials presented ) and, consequently, collection infrastructure and costs, each of the
three geography categories above were split to identify groups with higher and lower levels
of deprivation.

Mixed Urban/Rural, higher deprivation (53 LAs);
Mixed Urban/Rural, lower deprivation (49 LAs);
Predominantly Rural, higher deprivation (67 LAs); and
Predominantly Rural, lower deprivation (68 LAs).
Figure 5 above shows that a number of authorities lie very close to the classification
boundaries. In these cases, it may be useful for some authorities to also analyse the ICP2
results from a neighbouring rurality category. Some authorities may also have wide
variation in rurality across the authority area and may find it useful to apply the results from
different ruralities to each of those areas. Local Authorities can review which category they
have been allocated in Appendix 1.

5.0
Baseline Assumptions
Typically a baseline is set up to reflect the current recycling and residual collection in an
authority so that all scenarios can be compared against it. In ICP2, the baseline model is
used to set up the context (geographical and operational) of the rurality and, to do this,
data for the residual waste collection is used. It ensures that all scenarios are modelled
against the same authority background.
5.1
Waste composition
The waste composition used in the KAT models is based on Defra’s Updated compositional
estimates for local authority collected waste and recycling in England, 2010/117. The
kerbside recycling and residual waste composition was translated across into the material
categories present in KAT.
Each of the scenarios assumes that a free garden waste collection is present though is not
modelled for costs. Since capture of garden waste is typically high it is assumed therefore
that the 15.5% of the kerbside residual and recycling waste composition that represents
garden waste is reduced to 4% (representing the amount in residual), and the other
materials adjusted accordingly to bring the total back to 100%.

Household Numbers
This study focussed on collections from kerbside rounds and does not include collections
from flats. This is because both the logistics of collecting from flats, and performance
achieved from them, tends to be quite different to kerbside operations.
The average dwelling stock for each rurality was calculated using the 2008/09 dwelling stock
figures for each authority in the particular group. Operational residual waste collection data
was gathered from a sample of authorities from each rurality group and the percentage of
housing stock that were flats were calculated via 2001 census data for those authorities.
The flats percentage was then removed from the dwelling stock, and the remaining figure
rounded to provide the number of kerbside households to use in the modelling for each
rurality.

Operational Data for setting the baselines
The baseline set up in KAT for each rurality takes account of the average geography,
housing density and travel distances within the authority, as well as work rates of crews, in
order to calculate a baseline rate of round productivity. The baseline rate of productivity is
projected into all the modelling scenarios to allow for like-for-like comparisons. It is
therefore important to make sure that the baseline matches up closely with what actually
happens in the local authority being modelled.
As ICP2 uses 6 fictional authorities to represent the 6 rurality groups, it was vital to get
robust data from actual authorities within those rurality groups to inform the baseline. The
following data on residual collections was gathered from over 90 authorities:
· Frequency;
· Containment;
· Number and type of vehicles;

Crew sizes;

Time to travel from depot to start of round;

Unloading Time;
Time to travel from unloading to depot;
Number of loads per day; and
Round sizes.
82% of English local authorities used a wheeled bin for collecting residual waste in 2013/14.
Wheeled bins were therefore used in the modelling. The operational data collected was
filtered to remove sack collections and any collections using split vehicles. It was also
filtered to focus on collections operating over five days as five-day working was more
prevalent than four-day working when the data was collected.
Weekly residual waste collections were more prevalent than fortnightly collections in
ruralities 1 and 2 so the baseline data was set up to reflect this. Fortnightly residual waste
collections were modelled in the baselines for ruralities 3-6.
The key average values taken from the gathered data and fed into the baselines are listed in

The average unloading time of 18 minutes was used across all ruralities. The most common
working day length was 6.5 hours. This is the time from leaving the depot to returning at
the end of the shift but excludes breaks.
The numbers of households in the baselines were divided by the average round size to
determine the number of vehicles required. The data for existing services also showed that
a driver plus 2 loaders was the most common crew levels for wheeled bin residual waste
collections.

Scenario assumptions – operational
6.1
Containment
Residual waste collections are modelled with a 180 litre wheeled bin when collected weekly,
and a 240 litre wheeled bin when collected fortnightly. For each scenario all households are
modelled with the same containment and it is assumed that each household can
accommodate a wheeled bin.
Where food waste is collected, the householder is provided with a 5 litre indoor caddy with
liners and a 23 litre outdoor caddy.
The containment for the dry recycling collections depends on the type of collection. The
containers for each scheme type are listed in Table 5. The effective weekly dry containment
capacity shows how much volume is available to the householder on a per week basis and
ranges from 100 to 200 litres.

ICP2 – Online Tool Modelling Assumptions Technical Annex

Table 4 are applied to all the scenarios.
6.5
Loading and collecting times
The time taken to collect a container and to load the contents onto the vehicle is critical to
the outputs of the modelling process. Collection time is defined as the time taken to pick
up/gather the container and be ready to take it back to the vehicle. In other words, the
time taken to grasp the handle of the bin or for box collections the time to gather the
box/sack combination. Loading time is defined as the time taken to load the contents of the
container onto the vehicle and be ready to return the container to the set out point. For
wheeled bins, this is the time it takes to hook the bin onto the vehicle, for the emptying
cycle to complete, and to unhook the bin (total of 10 seconds). The time taken to tip
materials from a specific container tends to be standard regardless of the mix of materials in
the container.
The time taken to sort materials at the kerbside depends on the mix of the materials in the
container, and the number of materials present. The loading time for the multi-stream
collection is therefore calculated individually for each specific multi-stream scenario (as the
yeild would impact on the number of materials to sort).
The collection and loading times, plus the time to go from the vehicle to the set out have
been obtained from the filming of recycling collections and analysing the actions of the
crews.
6.6
Bulk density
The bulk density of materials collected dictates when a vehicle is full, with the determinant
being either its volume or weight limit. The assumed individual material bulk densities
represent uncompacted material on a vehicle (as compaction is applied subsequently).

Scenario Assumptions - Performance
7.1
Performance Yield Differentials
Kerbside dry yields were analysed from local authorities that met the following thresholds:
·
80% or more households in the authority that are offered a recycling scheme are all
given the same scheme. This means that authorities that had a scheme change mid-
year, or have two schemes in operation in large areas within the authority were
omitted from the analysis. The 80% threshold was important so that performance
could be assigned to a single scheme type.
·
Collect paper, card, cans, plastic bottles and glass from the kerbside. The combined
yield of ‘all 5’ materials was used in the performance differential analysis.
The ‘all 5’ yields were adjusted for contamination (see section 6.2) and analysed for each
rurality group. The upper quartile yields for sample authorities in each rurality are given in
Figure 6.
Figure 6 Step-wise progression of upper quartile performance across ruralities
The trend in Figure 6 showed a step-change in the following sequence:
R6 – predominantly rural, lower deprivation (highest yield)
R4 – mixed urban and rural, lower deprivation
R2 – predominantly urban, lower deprivation
R5 – predominantly rural, higher deprivation
R3 – mixed urban and rural, higher deprivation
R1 – predominantly urban, higher deprivation (lowest yield)
ICP2 – Online Tool Modelling Assumptions Technical Annex
29
A 16 kg/hh/yr increase in yield was applied to each of the ruralities which gave an 80
kg/hh/yr overall difference between R6 and R1, matching well with the difference in Figure
6.
To understand the difference in kerbside yields between difference scheme types, yields
were analysed, looking at confidence intervals around the mean, to understand the variation
across authorities within each Rurality group. Combining this with the step-change for
rurality enabled the calculation of a set of performance yield differentials.
From the monitoring of performance benchmarks of actual schemes in operation between
2010/11 and 2012/13, it was felt that the performance differentials developed using
2010/11 data were still applicable in 2012/13. The differentials were therefore applied to
2012/13 upper quartile yields for each rurality group to give the total ‘all 5’ yields for each
rurality-scenario combination.
This ‘all 5’ total yield was split to give yields for the individual material streams. The split
applied for each rurality was calculated from the distribution of material yields of the
authorities in the top quartile for each rurality group. For example, in rurality 1, the split of
materials for authorities in the top quartile is as follows:





45% Paper
16% Card
5% Cans
27% Glass
7% Plastic bottles
Since all the scenarios included plastic pots, tubs and trays (PTT), a yield for PTT needed to
be added. Reviewing the available waste composition studies of the authorities included in
the analysis showed that where PTT were collected, the ratio between bottles and PTT was
55:45. The plastic bottle yield derived from the ‘all 5’ was therefore scaled to produce the
PTT yield.
The total yields excluding contamination for each rurality-scenario combination are provided
in Figure 7.
ICP2 – Online Tool Modelling Assumptions Technical Annex

Figure 7 Modelled dry recycling yields for each scheme/rurality combination
7.1.1 Food Yields
For the scenarios collecting food waste, the expected yield of food was derived from WRAP’s
food waste ready reckoner11. This calculation links the yield of food waste collected to the
level of deprivation and frequency of residual waste collection. It provided the following
yields:

These yields are indicative and dependent on the provision of liners and the use of clear and
regular communications. The cost of food liners has been included in the model but the
cost of communications has not.
7.2
Contamination rates – dry recycling
Where waste composition studies were available (between 2008 and 2012) for the
authorities meeting the selection thresholds, the level of non-targeted material that gets

ICP2 – Online Tool Modelling Assumptions Technical Annex
31
collected at the kerbside was analysed. Contamination was defined as non-targeted
material.
7.2.1 Co-mingled and Two Stream contamination estimates
The sample size was sufficient to analyse fortnightly co-mingled collections with fortnightly
residual (SS 2W:2W), but not sufficient to look at two stream collections, or co-mingled
collections with weekly residual, in isolation (especially as the associated yields clustered
around lower performing authorities rather than giving a range of performance).
A different approach was therefore developed, combining all the co-mingled and two stream
data points into one dataset. This dataset was split into different recycling/ residual waste
frequency combinations:
· weekly recycling with weekly residual waste;
· fortnightly recycling with weekly residual waste; and
· fortnightly recycling with fortnightly residual waste.
The groups were compared and there was no statistically significant difference between the
mean contamination rates of these groups.
The relatively low yields for the two-stream collections and other co-mingled collection
frequencies were compared with the lower yields of the SS 2W:2W dataset. Again there was
no statistically significant difference in mean contamination rates between these two groups.
Since no significant differences were found between co-mingled and two stream collections
at low yields, and between different recycling and residual waste frequency combinations,
an exponential function for contamination was determined from the combined dataset. This
function was applied to all co-mingled and two-stream collections. Linear and polynomial
models were considered however the best fit of the data was achieved with the exponential
function.
The function is valid for the sample and the range of yields used to construct it. Caution
should be applied in using the function on yields that exceed the modelled range.

7.2.2 Multi-stream contamination estimates
Using contamination estimates from waste composition studies for multi-stream collections
do not take into account the reduction of contamination that occurs through crews leaving
non-targeted material in the container for the householder, instead of loading them on the
vehicle, because the samples for waste composition studies are taken prior to the crews
sorting the material at the kerbside. Reviews of pre-2008 composition data, applying an
assumption that half the contamination at the kerbside would be eliminated by operatives,
produced a 2% contamination rate. The 2% figure was applied to the yields calculated from
WDF but it should be noted that the tonnages within WDF for multi-stream authorities are
sometimes net of contamination identified at the transfer station as the weighing of the
material occurs after bulking for onward transport to the next destination for that material.
The contamination rates derived above were applied to collected yields at the kerbside to
give an indication of ‘adjusted’ yield.

7.3
Waste arisings
Analysis of the kerbside arisings (residual, dry and food), for the authorities used to
generate the performance differentials (Section 7.1), showed an average difference in
kerbside arisings of 55 kg/hh/yr between authorities with weekly residual and those with
fortnightly residual collections12. Combining this with the different dry performance
differentials and food waste yields across the ruralities, the following kerbside arisings yields
were calculated:

745
These yields were multiplied by the household numbers and then used as the kerbside
waste arisings for the models.
WRAP’s study ‘Analysis of recycling performance and waste arisings in the UK 2012/13 13’
shows no statistically significant difference between the effective weekly residual
containment capacity (a pseudo measure of frequency) and overall waste arisings.
Therefore even though authorities often notice changes in kerbside arisings upon changing
residual waste frequency (as assumed above), the material is likely to be diverted into other
streams (such as HWRCs).
7.4
Set out and participation rate
The study looks at good practice schemes (which assumes effective communications) so it
was assumed that participation levels would be high. Considering the difference in
performance between the 6 ruralities it was assumed that they would not all have the same
participation rate. The maximum participation rate for the highest performing rurality group
(R6 - Predominantly rural, lower deprivation) was set to 90% and the maximum rates for
the other groups reduced by 2 percentage points based on their relative performances. This
gave the following maximum participation rates:
6)
4)
2)
5)
3)
Predominantly Rural, lower deprivation – 90%
Mixed Urban/Rural, lower deprivation – 88%
Predominantly Urban, lower deprivation – 86%
Predominantly Rural, higher deprivation – 84%
Mixed Urban/Rural, higher deprivation – 82%
12
The 55 kg/hh/yr figure was derived from the 2010/11 dataset. A subsequent analysis of 2012/13 data shows the difference
beween median kerbside arisings in England to be 49 kg/hh/yr and the difference at upper quartile level to be 57 kg/hh/yr.

ICP2 – Online Tool Modelling Assumptions Technical Annex

1) Predominantly Urban, higher deprivation – 80%
Due to the lack of generalised participation rate studies, it was assumed that providing there
is sufficient containment capacity, the type of scheme (multi-stream, single stream comingled, two stream co-mingled) was less of an influence on participation than the
frequency of the recycling and residual waste collection. Fortnightly multi-stream has the
lowest effective weekly recycling containment capacity (100 litres per week) so it was
assumed that it too would have lower participation compared to weekly multi-stream,
fortnightly co-mingled and fortnightly two-stream.
To reflect the differences in participation due to frequency of collection of recycling and
residual waste, the following reductions in maximum participation rates were applied:
·
·
·
Difference between fortnightly residual scheme and weekly residual waste scheme
(for co-mingled, two stream and weekly multi-stream) - 8 percentage points
Difference between multi-stream fortnightly residual waste with fortnightly recycling
from multi-stream fortnightly residual waste with weekly recycling – 5 percentage
points
Difference in multi-stream weekly residual waste with fortnightly recycling and multistream weekly residual waste with weekly recycling– 2 percentage points.

The set out rate applied was dependent on the frequency of the recycling collection. From
analysing the limited data available on set out and participation, set out was 8 percentage
points lower than participation when recycling was collected fortnightly, and 20 percentage
points lower when collected weekly. This function was applied to the participation rates in
Table 11 and then rounded to the nearest 5% to produce the set out rates (KAT models set
out in intervals of 5%).

Vehicles
The vehicle capital costs reflect the technology required to meet Euro VI regulations for
emissions. In the modelling, the capital cost is annualised over a 7 year period at a
financing rate of 2%.
The standing cost includes insurance, tax and licensing for the vehicles and is calculated as
5% of the capital plus road tax. The running costs cover maintenance, tyres and oil as is
calculated as 10% of the capital for all vehicles except the 7.5 tonne dedicated food waste
vehicle where running costs are 7.5% of the capital.

Fuel is assumed to be £1.29 per litre. This is based on the price for diesel (28/06/13)14
excluding VAT. The fuel price is then increased by 11% to account for the reduced fuel
efficiency resulting from the technology required for the Euro VI regulations.
8.3
Crews
The annual cost for drivers and loaders included salary, on-costs, holiday and sickness cover
(16.5% of salary and on-costs) and pension (12% of salary and on-cost). The total cost per
driver and loader were therefore:
 Driver £30,816
 Loader £23,966
Supervision costs are included as 9% of the total crew costs.
8.4
Overheads
To account for a contribution towards depot cost and local overheads, a cost per household
was assumed that was graded depending on household size:
Table 14 Direct overheads
Authority size (households)
20-30,000
40-50,000

Direct Overheads per
household (£)

Direct (or Local) overheads are individual to each authority therefore the values assumed
above just provide a contribution towards overall local overheads for the waste service.
Corporate overheads are additional to the local overheads and are assumed to be 6% of the
total collection costs for each service.
9.0 Post-collection process assumptions
The KAT models provide the costs and tonnages associated with the collection of recycling
and residual waste from the household and taking it to the transfer station/disposal site.
These costs are the collection costs used in the Online Tool.
The user can then define their own bulking and haulage, sorting fees, material revenue,
treatment and disposal costs. ICP2 does provide default values which are explained in this
section.

Material revenue
Where an individual material is separately collected and sold to the reprocessor from the
transfer station, the revenue value received for that material is the 2012 average taken from
WRAP’s Material Pricing Report (MPR)15. All material values except glass taken from the
MPR are ‘ex-works’ which means that the cost of bulking and hauling the material is
accounted for within the price. For glass, a £10/tonne bulking and haulage fee has been
subtracted from the reported MPR price to make it equivalent to the other materials.

Input composition and tonnage was determined by the ICP2 performance differentials and
the KAT modelling. This was slightly different for each scenario/rurality combination. The
distribution of the input tonnages into the MRF material output streams was based on MRF
output compositions and confidential industry data. This provided a mass flow of tonnages
in and out of the sorting facility.
The capital and operating costs of the sorting facility were based, as far as possible, on
financial outturns from different facilities. The operating costs and the annualised capital
costs are divided by the tonnage throughput to give a processing cost per tonne. The cost
of disposing of reject material is added to the processing cost and corporate overhead and
profit is added as a percentage19 of the total. The total of these components gives the
sorting cost per tonne of material input. The outputs of the sorting cost tool were validated
by industry experts.
The basket price for each sorting scenario was based on the average 2012 values from the
MPR but a MPR to MRF conversion factor has been applied to specific materials to account
for market conditions and material qualities. The adjustment factor was determined by
comparing confidential real MRF sales values to the MPR values for the same period.
Combining the sorting cost and the basket price gave a “gate fee” for each sorting scenario
and has been averaged across all ruralites.

The treatment costs for food waste and the disposal costs for residual waste were
accounted for using gate fees. The gate fees were taken from the 2012 gate fees report21
and the 2012/13 landfill tax value was applied (£64) for disposal.
