The future of food waste treatment - Black Soldier Flies Larvae
Hong Kong landfills will be full by 2019, and 42%
of that is food waste! That’s 3,869 tons/day!
= 250 double-decker busses thrown
into land-fill EVERY DAY
How may we reduce
household food waste
from ending up in
landfill?

Personas of consumers generating the food
waste in households
A BSFL farm can turn food waste into fish feed +
fertilizer for organic produce! How does it work?
Why use Bio Compost System over Electric
Composting Machine?
Financially
sustainable
• Cultivated larvae can be sold as fish feed (10,000 tons
demand annually in HK), which has much higher market value
than traditional compost
Space and
logistically efficient
• Small operation footprint and highly efficient and mobile (to be
located closer to source of waste to reduce logistic needs
Energy efficient
Over supply of
compost in HK
Minimal postprocessing waste
• Minimal energy consumption compare to electric composter
• Hong Kong cannot absorb excessive compost
• Mainly organic matter from deceased adult flies

Project BSFL creates a loop of incentive and
rewards for food waste collection at households
Personal
accountability
Incentive
Using produce grown with
larva poop as incentive for
household food trash
separation/collection;
income from selling fish
feed compensates
operational cost of project
