Optimising the Unseen
The first ai-driven platform empowering food & drink manufacturers to take action against food waste.
The Problem
7x
more is lost in manufacturing compared to retail
70%
of the waste at manufacturing stage is edible
40%
of food produced never makes it to a supermarket shelf

You can’t optimise what you can’t see
What manufactures see:
Volume of waste leaving each site
Revenue from animal feed and AD
What manufacturers don’t see:
Key drivers of waste
Total economic cost of waste
Edible food going to waste
Full social and environmental impact
The Impact
~ £6.7B
the yearly cost of food waste for UK manufacturers
4-9%
potential reduction in carbon emissions for manufacturers
5-10%
increased cost of goods —devastating in a low-margin industry
£ 250-300 M
additional annual charity food cost due to inefficient surplus redistribution
