Alfa Laval, which provides centrifugal separation technology, is collaborating with anaerobic digestion (AD) operator Bisviridi to elevate the sustainability potential of organic and food waste recycling
The partnership integrates Alfa Laval's Prodec Oil Plus decanter, designed for efficient oil separation, with anaerobic digestion to convert oil and fats waste into biofuel. This groundbreaking process, developed and patented by Bisviridi, produces Bio Crude, an eco-friendly alternative to oil-based fuels.
Notably, Bio Crude can be refined into sustainable aviation fuel (SAF), aligning with the aviation industry's decarbonisation goals and entering an emerging market.
The Alfa Laval Prodec Oil Plus decanter, a key component in the Bisviridi process, integrates into any AD facility. Prior to methanogenesis, the decanter efficiently extracts oil from organic waste, removing oils, fats, and grease content. This allows the remaining components to be reintroduced into the AD system, with minimal impact on biogas production. The resulting bio crude boasts purity levels of up to 99.5%, making it an ideal feedstock for refineries to produce biofuel for the SAF market.
Through a recent collaborative effort with BioteCH4, the AD plant can achieve a remarkable production capacity of up to, but not limited to 300 litres of oil per hour, all while seamlessly increasing and diversifying the AD operator’s revenue stream. The Prodec Oil Plus decanter's innovative design ensures easy operation and maintenance, resulting in minimal payback time and total cost of ownership. It is available as a standalone component or as a plug-and-play skid, allowing for effortless integration into existing AD plants and processes.
Lee Dobinson, CCO of Bisviridi, said, “The fluctuation in oil prices over the last few years and the need for large biodiesel companies to find new sources of sustainable waste-oil streams has led us to develop a way of harnessing this waste material and diversify the output of the BioteCH4 business, increasing its revenues and sustainability. We are thrilled to collaborate with Alfa Laval, merging our AD expertise with their successful history in separation technology to further refine this process and potentially achieve large-scale production worldwide."
Carl Rehncrona, business unit president at Alfa Laval, said, "Alfa Laval's comprehensive product knowledge and global service presence will fully support the entire lifecycle of the decanter skid. Together with Bisviridi, we are setting a new standard in AD, and we firmly believe that we can make a significant positive impact on the industry by transforming food waste and creating a more sustainable and resilient future."
