Coloring is sometimes done to mulch to give the product a richer, longer-lasting color. It is an after market add-on and the most common colors include gold, rich browns, reds or blacks. Customizable colors are sometimes available depending on your provider. Coloring can be done at grinding, but it is usually done with a trommel screen during the drum rotation. This technique creates more consistency and the ability to customize your landscaping.
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 uses 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.
Screens are very useful with compost because it helps provide the most consistent end product for consumer use and higher profitability due to reduced waste.
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:
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. A screen helps filter out any larger pieces that cannot be used in RAS applications.
Topsoil is the upper, outermost layer of soil, usually the top 2 inches (5.1 cm) to 8 inches (20 cm). It has the highest concentration of organic matter and microorganisms and is where most of the Earth’s biological soil activity occur.
