Pallet businesses and sawmills produce significant volumes of waste wood material as a by-product of their operations. Suppliers of grinding and shredding equipment can help them convert wood waste to other marketable products.
Whether the company is fully integrated, with its own sawmill or scragg mill, remanufacturing lumber into pallet parts, making pallets from cut stock, or repairing pallets and conducting other pallet recycling operations, new and recycled wood waste accumulates. The slabs, trim ends and shims pile up; at pallet recycling operations, broken or otherwise flawed used pallet parts and entire pallets mount up.
Waste wood is a solid waste challenge. How can companies dispose of the material? Some companies explore another option: how can they convert waste wood to a value-added product and market and sell it to add to their revenues.
Various types of grinding and shredding equipment have provided solutions to pallet companies and sawmills. Technological advances have improved both the product produced by the machinery and their performance. Suppliers offer systems to process relatively small volumes of waste wood or an individual pallet to much larger machinery that can grind entire pallets or skids and other large wood debris, such as limbs or stumps. Grinding and shredding machinery varies widely in terms of production capacity, size, portability, and other factors.
With some effort and marketing, companies are developing new wood fiber products and markets where they may be sold. These include bedding for livestock, surface coverings for playgrounds, landscape mulch, supplementary feedstock for fiberboard production, fuel, compost, and others.
While some companies have invested in machinery to grind or shred waste wood, others may choose simply to partner with such companies by supplying them with waste wood.
From time to time, Pallet Enterprise publishes articles that may give particular focus to the grinding operations of a pallet company or sawmill business.
In a recent article, the owners of Tree Brand Packaging told how they were forced to look for a solution after they had been able to give away their waste wood for years. When the giveaway arrangement dried up, the ends and blocks began to pile up. Tree Brand elected to invest in grinding machinery to convert its waste wood into a saleable product: mulch. The answer was a hopper-fed grinder now producing about two trailer-loads of mulch per week. Most of the mulch is sold wholsale to landscapers.
Wood Waste Solutions, a major Canadian pallet recycling company whose growth has been heavily tied to the automotive industry, made significants investments in grinding equipment that enabled it to become Ontario’s largest wood processor. The company has a wood fiber processing operation and also a mobile service for grinding material at customer locations, including other businesses and municipalities.
Pallet companies and sawmills should carefully consider the pros and cons of investing in grinding or shredding equipment, just as they should for any strategic business decision. They may need to investigate markets for mulch and other wood fiber products and to carefully determine their costs — in other words, a sound business plan.
On this and the following pages, we present information from suppliers who provide grinding and shredding machinery and equipment. The companies are listed in alphabetic order with information about how to contact each one.
