Clearfleau - food processing waste treatment

Food Processing Waste

Reducing food processing waste treatment costs and the
environmental impact

The food industry faces ongoing pressure to cut costs and to reduce its carbon and environmental footprint. Many food companies are being hit by increased trade effluent charges and carbon taxation. Clearfleau will reduce discharge costs for liquid effluents including:

  • Waste water arising from food processing
  • Wash down residues and effluents
  • Blancher liquors or process condensates
  • Unused ingredients and co-products
  • Other bio-waste and reject products

Liquid anaerobic digestion is an ideal process for treatment of food processing waste, which includes organic material, sugars, oils or fats. Our anaerobic treatment process converts the volatile solids into biogas to generate renewable energy. Clearfleau systems can be integrated with existing treatment systems and are fully bio-secure as the import of additional materials to supplement the biogas potential is not required.

Potential financial benefits include:

  • Reduced costs for sewer discharge and off site waste disposal
  • Revenue from FITs and the RHI for on site energy generation
  • Reduced costs for purchase of electricity and other fossil fuels
  • For some sites, tax savings from reducing the carbon footprint

Information on flows and loads is used to evaluate biogas and payback potential. On-site trials with our mobile anaerobic digestion trials unit (Small Scale Production Plant – SSPP) can be undertaken to optimise performance and provide process guarantees.

In addition to cutting effluent disposal costs, the food sector is being encouraged to use less water and recycle more. The reduction in COD load by over 95% in the digestion process creates the opportunity for recycling grey water to replace existing supplies, for boiler feed water and other non sensitive uses.

Clearfleau is focused on cost effective generation of biogas from liquid effluent that can be a major cost burden to many food processors. On-site anaerobic treatment not only reduces costs but also generates revenue. With suitable liquid food processing waste, net revenue from anaerobic treatment can be significant.

 

UK Integrated Pollution Prevention and Control regulations (IPPC) require companies to make continual improvements in environmental practices. ISO 14001 requires periodic environmental audits. Investment in renewable energy and water recycling is eligible for enhanced capital allowances (ECAs). The industry also needs to reduce energy consumption and its carbon footprint, to reduce its CRC tax commitments.
