Food waste valorisation is the conversion of food waste or by-products into higher value products that contribute back to the supply chain. This contributes to the circular economy approach where useful material, once seen as waste, is recycled back into the supply chain to create new products.
In closing the food resource loop, food waste valorisation is a smaller and preferred loop. It extracts more value from food waste (e.g. converting into food, feed or other products) from food waste compared to other more established solutions in Singapore, such as anaerobic digestion to convert food waste into biogas, or aerobic digestion systems that convert food waste into non-potable water, compost, or liquid nutrient.
[NEW] Singapore Food
Agency’s Study of Food Waste from Local Food Systems
To better understand food waste and support circularity in
food systems, the Singapore Food Agency (SFA), with the support of the National
Environment Agency (NEA), commissioned a study. The study surveyed local food
processing companies between August 2022 and June 2023.
In total, the study surveyed data from 74 companies, and
mapped ~174,300 tonnes of homogeneous food waste. A high-level summary of the waste
streams mapped is as follows:
The findings include a broad overview of the valorisation
rates of the studied waste streams, the homogeneous food waste treatment
approaches in 2022-2023, and material flow analyses (MFAs) of some of these
waste streams.
