Purac move confirms its positioning as a new force in solid waste treatment in the UK

BTA process plus Purac 'knowhow' offers an impressive pedigree in waste treatment

Purac has signed a license agreement for the BTA waste pre-treatment and anaerobic digestion process (The BTA Process) with Munich-based Biotechnische Abfallverwertung GmbH & Co. The license agreement is exclusive for the UK and Ireland.

The BTA process involves a pre-treatment system where biodegradable organic materials present in wastes are pulped with water in a patented 'hydro-pulper' to form an organic slurry. Plastics, dense inerts, grit and glass are removed from the pulped waste, and the clean pulp is then pasteurised and treated in an anaerobic digester producing an energy rich biogas and a stabilised compost-like material for recycling.

One advantage of the BTA process is that contaminating materials are separated out right at the start of the process, optimising the quality of the treated material for recycling, and maximising the biogas yield. The wet separation system effectively removes batteries, metals, plastics and glass from the waste prior to treatment leaving a high quality organic material for recycling as compost.

The BTA process has 26 reference plants worldwide of all sizes and types - more references on solid waste than any other anaerobic digestion process. Added to Purac's extensive track record in anaerobic digestion of sewage sludge, with over 20 anaerobic digestion plants installed in the UK over the past 15 years, with project values up to £25 million, the future for Purac's new business looks bright.

Jerry Quickenden heads up Purac's Solid Waste team: "Today, Purac can offer a proven anaerobic digestion process for solid waste and a proven turnkey delivery capability to clients throughout the UK and Ireland. This move will be a major factor in the success of our new business development as we establish ourselves as major players in the solid waste treatment technology sector over the next few months."
