Over 825,000 litres of used cooking oil was collected from Stonegate Pub Company’s kitchens and recycled last year, it has emerged.
The pub chain, which runs 650 sites around the UK, worked with Northamptonshire-based specialist Olleco to manage the recycling process, which sees the oil refined into a range of products, such as industrial oils and renewable fuels.
Stonegate’s annual accounts for 2016, published this week, give a fascinating insight to the scale of waste produced by a multiple-site operator running hundreds of kitchens.
For the 12 months to 25 September 2016, Olleco collected some 826,751 litres of cooking oil from Stonegate pubs, the equivalent to 762 metric tonnes.
In the prior year the figure totalled 745 tonnes.
Stonegate estimates that the measures it takes to recycle oil are the equivalent of saving 1,412 tonnes of carbon a year.
Olleco typically transports the used cooking oil to one of its three processing sites located in Southampton, Wales and Liverpool. Once there, the oil is de-packed, heated, cleaned and filtered and then sent to its biodiesel plant in Liverpool for recycling.
Meanwhile, Stonegate works with Veolia Environmental Services for waste collection and recycling services.
Currently, 53% of its waste goes to glass recycling facilities, 11% to dry mixed product recycling and 4% food. The remaining 32% is of general non-hazardous industrial classification. Of this, 16% is consigned to Energy Recovery operations and 80% is diverted from landfill to other recovery facilities. The remaining 4% is landfilled.
Stonegate is the fourth largest managed pub operator in the UK in terms of number of pubs. Last year it made a pre-tax profit of £16m on sales of £642m.
