Some quantity of spoiled and damaged foods are an inevitable part of supermarket and food manufacturing operations. Being able to divert these food products from landfills has been a challenge given that many foods are sealed in packaging. However, BioCycle details how one Massachusetts company, E.L. Harvey & Sons Inc., invested in mechanical separation technology to remove packaging from food. E.L. Harvey received a grant through MassDEP’s Recycling Business Development Grant (RBDG) program which enabled them to purchase and install the separator.
E.L. Harvey is a hauling company that handles trash, recycling, food waste, and construction and demolition debris. E.L. Harvey was a good candidate for depackaging equipment because they service many supermarkets and food manufacturers which dispose of a large amount of packaged food products.
Because E.L. Harvey does not have a permit to process food and yard waste on site, they send their organics to anaerobic digestion (AD) facilities, compost sites, and animal feed partners. The depackaging machinery is versatile enough to modify the resulting food slurry to best suit whichever type of operation they send it to. For example, if it is going to a compost site rather than an AD facility, they will make the food slurry drier.
The machine used by E.L. Harvey is called the Scott Turbo Separator and can remove packaging from food whether it is plastic film, cardboard, or plastic containers. Glass cannot be processed in the separator because the final product can contain too much broken glass to be acceptable for composters and AD facilities. E.L. Harvey does not recycle any of the packaging that goes through the separator currently because it is contaminated by food and would take too much time, energy, and water to clean.
RecyclingWorks created a document listing all of the companies currently accepting packaged food materials in Massachusetts (updated February 2019). In addition to packaged food, RecyclingWorks created a guidance page for supermarkets which contains resources and case studies regarding common materials generated by the sector.
