Food Waste and Loss: The Benefits from Circular Economy
As the world’s population grows, it is anticipated that waste production and food consumption will both rise. Food waste and loss have both negative environmental and economic impact by contributing to the worlds greenhouse gas (GHG) emissions and biodiversity loss.

A linear economic model is a “take, make, use, dispose” system, where products are made, used, and then discarded as trash. As a result, the value of resources and goods is expected to decline, prices will fluctuate because of resource shortages, and the supply of raw materials will be unstable because of overconsumption. In continuity there is a creation of greenhouse gas emissions which contributes to environmental degradation and climate change.
However in a circular economy model, actions at every stage of the food value chain intend to restore the status of the entire system by eliminating the idea of waste. Thus, this economy model creates additional economic opportunities and products which can be used throughout systems and society. Ellen Macarthur Foundation explains the circular food economy in below diagram. Also, Sustainable Development Goal-12 focuses in the reduction of the food waste and loss at the production, consumption and retail level.

Benefits of circular food economy :
At the production level:
Food loss at the farm level is largely a result of difficulties with crop storage, rigid contracts with purchasers, and agricultural byproducts. Farmers and producers can aid in the shift to a circular food economy by optimizing their operations, using regenerative techniques, reducing waste streams, and finding new applications for products that are typically discarded.
The benefits of the circular bio-based economy for farmers in terms of both the economy and the environment are also highlighted by the European Farm to Fork Strategy. The Strategy explains that farmers may boost revenue and generate jobs by embracing opportunities to use biofertilizers, protein feed, waste streams, and renewable energy.
At the consumption level:
According to the UNEP Food Waste Index, retail businesses and food services waste 5% and 2%, respectively, of the total amount of food available at the consuming stage of the supply chain.
An UN course on food waste prevention explains how to measure and report for food waste at different points in the food chain and how to take effective preventative actions.
EIT Orbisk is also working to cut down on food waste in the restaurant businesses. Orbisk integrates smart cameras, weighing scales, and waste bins using AI technology to track food waste down to the ingredient level. This is intended to help restaurants reduce waste and increase profit margins by helping them make more educated decisions about when and how much food to buy.
