Sweden-headed Alfa Laval AB, a global leader in heat transfer, centrifugal separation, and fluid handling, and Bisviridi, a new company part of the BioteCH4 group, the leading anaerobic digestion (AD) operator in the United Kingdom, are collaborating to elevate the sustainability potential of organic and food waste recycling.
The partnership integrates Alfa Laval’s state-of-the-art Prodec Oil Plus decanter, designed for efficient oil separation, with anaerobic digestion (AD) to recover oil and fat waste and convert it into a biocrude for biofuel production.
This groundbreaking process, developed and patented by Bisviridi, produces a biocrude that can be refined into sustainable aviation fuel (SAF), aligning with the aviation industry’s decarbonization goals and entering an emerging market.
Lee Dobinson, Chief Commercial Officer of Bisviridi, highlights the value of the partnership.
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 diversifying 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, said Lee Dobinson.
Recover every drop of value
The Alfa Laval Prodec Oil Plus decanter, a key component in the Bisviridi process, seamlessly integrates into any AD facility, offering numerous benefits. Before methanogenesis, the decanter efficiently extracts oil from organic waste, removing fats, oils, and grease (FOG) content.
This allows the remaining components to be reintroduced into the AD system, with minimal impact on biogas production.
The resulting biocrude boasts impressive purity levels of up to 99.5 percent, 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.
According to the company, its 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.
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, said Carl Rehncrona, Business Unit President at Alfa Laval.
