Biomass is fuel that is developed from organic materials, a renewable and sustainable source of energy used to create electricity or other forms of power. Biomass can be created from sources such as forest residuals, waste wood (scrap wood), crops (such as corn stover), and other organically based waste residuals.
Compost is organic matter that has been decomposed and may be made from single source material or blended for specific application performance. Green waste materials used include: garden debris, kitchen scraps, manure, or yard and lawn waste.
Nutrient rich in composition, compost acts as a natural, healthy, organic fertilizer for your plants. It is typically a soil additive mixed prior to planting to provide nutrients and improve soil structure, but can also be used a protective mulch layer or top dressed to planted areas.
The ground material that is produced by Peterson horizontal grinders can offer more value if it is free of metal debris such as nails, bolts, and other ferrous hardware. Metal Recovery is pulling scrap metal from the debris stream with an optional cross belt magnet, or the optional magnetic head pulley and can be collected in a separate container or the metal collection box attached to the machine.
Metal recovery can provide an additional revenue stream as well.
Often made from bark, low value trees (non-merchantable stems) or wood waste, it can be made from a variety of materials, typically organic, but not exclusively. Organic mulches are typically a product that can decompose providing nutrients to the soil over time. Not all mulch materials are available commercially. Materials include:
Poultry Litter is made from spilled feed, feathers, bedding and other ground materials using a horizontal grinder. The specifications for Poultry Bedding are very tight in moisture content, and size, and no metal is ever allowed. Peterson horizontal grinders with bedding grates are ideal for making this type material.
Sometimes referred to as Reclaimed Asphalt Shingles (RAS); Recycled Asphalt Shingles are the byproduct of Asphalt Shingle Grinding. This is done by processing asphalt roofing shingles down to a smaller spec, usually 3/8”, in an effort to use recycled asphalt material in roadways, resulting in reduced road building costs and can lower amounts of material sent to a landfill. Adding RAS to the mix displaces some of the expensive virgin asphalt, saving costs on roads, parking lots, etc.
An undesirable, odd sized material that pass through the grates with minimal size reduction. Peterson machines are less likely to have spearing occurrences due to the up-turn rotor and three-stage grinding process.
