Compost & Food Waste Industry Challenges

Increased state and federal legislation is requiring more organic waste to be diverted from landfills and at the same time ensuring that only safe and environmentally beneficial compost be marketed.  Converting material including green waste, food waste, manures, and mixed organics into high-quality feedstock for compost is a vital step in the process.  This requires field-proven equipment like Compost grinders and screens that can hold up to some of the harshest materials in mass volumes using our industrial compost grinders.

Size reduction of food scraps and some other material, as well as the screening of incoming and outgoing material for quality purposes, is required with most composting systems. Many conversion systems require the addition of a bulking agent/carbon source (BA/CS) to recovered food. WSM's focused approach to all of this starts with understanding the characteristics of each material. All of our food waste recycling machines process differently and the expertise to know the best equipment to get the job done is part of the key to a successful system. Our ability to configure the correct components or engineer a complete processing system can help streamline your new or existing operation.

WSM Solution

With WSM's 70+ years of experience in grinding and screening, we've been adapting and developing equipment with some of the largest composting companies in the world since the early 2000s.

WSM's unique ability to supply individual components or complete, fully integrated systems means you can be confident that you're getting what you need for your operation.

WSM's Complete Organics Processing System typically starts with batch feeding of incoming pre-shredded waste into WSM's Chain Metering Bin, which meters feed material to the Severe-Duty Titan Trommel Screen. Our Light Fraction Separator removes plastics and light fractions before and/or after WSM's Vertical or Horizontal Grinder.  WSM can supply all conveyors, support structures, maintenance platforms, walkways and stairs, and picking stations. Optional project management supports your project and coordinates with your site engineer.
