A postharvest innovation is a handling or storage practice
or a method or tool that can be used to reduce food losses or food waste.
Innovations can be adapted from a variety of related fields (engineering, food
science, or packaging) or developed specifically for use in the postharvest
sector. PEF is pleased to share news and reports on postharvest innovations
with our network.

CONTAINERS & PACKAGING
Plastic crates can be reused many times, and then
recycled. Returnable plastic
crates (RPCs) are being promoted by many companies and associations.
Reusable Plastic Crate
CoolBot modules can be used to convert a typical window
style air conditioning unit (minimum temperature setting of 15C) to a
small-scale refrigeration systems that can reach as low as 2C.
