Garden and food waste processing

How can garden and food waste be processed? 

Food waste

The UK throws away approximately 11.8 million tonnes of food waste every year and much of this goes into landfills where it produces methane, thus contributing to global warming.

There are three key methods of recycling food waste into a valuable product - in-vessel composting, anaerobic digestion and thermophilic aerobic digestion.

Garden waste

Garden waste is a term used to describe wastes such as grass cuttings, pruning and leaves. Currently the UK collects around 350,000 tonnes of garden waste per year which is being composted and used in various applications every year.

Garden waste is recycled using a simple windrow process and will be composted down into reusable products.


Composting, whether in a home composting bin in the corner of a domestic garden, or within a central purpose-built facility, is a managed process.

In controlled, managed conditions, raw biodegradable materials (food and garden waste depending on the type of composting) are broken down by micro-organisms which results in a process in which the ingredients quite literally cook themselves into rapid decay.
