Separation of Black Soldier Fly (BSF)

Russell Eco Separator® improves the separation of Black Soldier Fly sustainable food protein from bio converted waste material

Founded in 2014, with production expanding exponentially in 2016, Entocycle breeds and harvests the Black Soldier Fly, whose larvae are fed on organic waste to convert it into high-protein body mass. These larvae, and the waste they produce (known as frass), can then be utilized for a variety of different applications. The larvae – the main focus of Entocycle’s process – are harvested to be used as a source of protein to feed animals in the agricultural industry, whilst the oil and frass produced are used respectively in biofuels, and as fertilizer.

The hatched Black Soldier Fly larvae are fed on pre-consumer organic food waste (such as used coffee grounds or brewers’ grain) in an indoor, environmentally controlled location. When the larvae have consumed enough organic waste and converted it into high-protein body mass, they are at a stage where the organic food waste can be turned into three valuable products: Insect Meal (protein), Insect Oil, and Frass (organic fertilizer).

Entocycle originally used a manual process to sieve the larvae, but since this proved to be both labor and time intensive, sought another more efficient method that would effectively scale up to cope with demand at its new pilot plant in London Bridge. Following a recommendation from other companies who had utilized the Russell Eco Separator® for similar uses, Russell Finex provided Entocycle with an innovative grading sieve, allowing it to exponentially increase its product throughput to 1.39 tonnes per hour, with a mean sieve time of around 177 minutes to harvest the protein.

With the installation of the round separator, this entire process from larvae to packaged feed takes 12 days. The length of time taken for this process is incredibly quick, in comparison to other more traditional methods, such as growing soy plants, or fishmeal. Overall, the Russell Eco Separator® offers businesses a cost-effective, reliable solution across a variety of different industries. Not only is it incredibly versatile, suitable for wet or dry applications, but, with up to four screens to enable separation into 5 fractions in one go, is able to increase the output of product and efficiently separate waste.

Russell Finex has a history of supplying separation equipment for a wide range of companies within the recycling industry. To find out more information about this application, and how it can be incorporated in your processing lines, please contact us.
