Multi-Stage Fermentation

The global food industry faces a serious problem of food waste creation. Regardless of the excess food being thrown out, innovative ways to manage food waste are needed. Using trash disposal sites for food waste only contributes to greenhouse emissions and depletes resources. The company offers advanced multi-stage fermentation services, facing this critical issue. Cutting-edge biotechnological processes are used to transform food waste into valuable resources, such as protein-rich biomass, thus supporting circular economy in the food sector.

The company's offering is a sophisticated multi-stage fermentation service aimed towards bio-treatment of food industry waste. This integrated system utilizes high-pressure thermal pretreatment (HPTP) alongside biological processes that focus on the growth of Yarrowia lipolytica yeast. This approach aids in the decomposition of waste, aid in the separation of oil and grease, and cultivate valuable yeast biomass.

Technical Principles

The effectiveness of our service is captured in its sequential stages:

• High-Pressure Thermal Pretreatment (HPTP): First, food waste undergoes HPTP. This thermo-chemical step uses heat and pressure to complex organic materials to be disinfected and physically hydrolyze complex molecules like starches and proteins into simpler forms. One major advantage of this step is the separation and liquefaction of oils and greases from the waste matrix.
• Biological Treatment with Yarrowia lipolytica: The nutrient-rich hydrolysate has been pre-treated and separated into these phases. "Yarrowia lipolytica" serves as a substrate for the cultivation of Yarrowia lipolytica. This oleaginous yeast is best known for his ability to grow on an extensive list of carbon sources especially fats and sugars. It assimilates the remaining organics efficiently purifying the waste stream and generating valuable yeast biomass which is rich in proteins and lipids. Moreover, the separated oils from HPTP stage may also be valorized or used by the yeast in some configurations.

Technical Features

• Resource Valorization: This process enables the recovery of valuable oils and fats and the generation of yeast protein biomass suitable for animal feed or other bio products.
• Pathogen Destruction: HPTP stage guarantees complete sterilization by eliminating the population of pathogens, thus lowering biosecurity threats.
• Robust Microbial System: Yarrowia lipolytica has a high tolerance to many inhibitory substances that are frequently present in food waste and has a broad range of substrates.
• Reduced Waste Volume: Reduction in the amount of waste that requires disposal is very significant.

Application Areas

• Food and beverage manufacturing plants
• Large-scale catering facilities and restaurants
• Supermarkets and food distribution centers
• Agricultural processing residues
• Municipal organic waste management programs with source-separated food waste.

Environmental Benefits

• Reduced Landfill Burden: Diverts significant quantities of organic waste from landfills.
• Lower Greenhouse Gas Emissions: Prevents methane generation associated with anaerobic decomposition in landfills.
• Circular Economy Promotion: Converts waste into valuable resources, closing the loop on nutrient and material flows.
• Reduced Water Pollution: Effective treatment reduces the pollutant load of wastewater.
