Description

Keenan Recycling is Scotland's largest food waste collection company. The business collects waste on behalf of waste management companies and councils. They also service restaurants, hospitals, prisons, and cafés and other businesses.

Potential circular economy impact

This solution reduces the amount of food waste sent to landfill and/or incinerators. This reduces greenhouse gas emissions.

The biogas created from the food waste can be used for electricity, gas and heating, helping to reduce our reliance on fossil fuels. 

The by-product left behind from the biofuel production can also be used as fertiliser. This benefits soil and food production and reduces our reliance on artificial fertiliser.

This solution also encourages sorting at the source by residents and businesses.
