Food Waste in Your Business

How to Carry Out a Detailed Food Waste Assessment

A detailed food waste assessment is an extension of the Source Assessment in that it still targets the different waste producing areas in a business but, instead of just weighing the food waste from each of the specified areas, you break it down into the different types of food waste.

Doing such a detailed survey will provide you with information on the key food types that are wasted regularly. This provides businesses with the detailed information required to target food waste prevention as close to its point of generation as possible and with key items to be focused on.

Detailed assessments should follow the general method outlined for the Source Assessment but may need to be altered somewhat depending on how and what is to be looked at in more detail. In general these will focus on the largest waste producing areas identified during the source assessment or on the largest, or most expensive wastes. Segregating individual food wastes as close to source, before it goes into the ‘source’ food waste bins, makes these assessments much easier.

Food that has been prepared but not served or sold is a key area as it has been purchased, prepared and then disposed of so has a high cost associated with it. When it comes to plate waste this can only be separated manually so different containers will be needed to take the different foods (e.g. meat, potatoes, vegetables) off the plates.

Food Retail

This can be used to identify trends and proportions of ordered stock that are being wasted. However, source assessment may still be of benefit in areas like the deli where specific foods (e.g. salads, breads, cut meats) may not be separated out.
