In Canada wood waste is largely banned from landfill and is not subject to diversion through municipal waste management programs. A quarter of all packaging used in the country annually is comprised of wood pallets, box pallets and other load boards, according to the latest data from the National Packing Protocol (NaPP).
Prompted by the supposed landfill crisis of the late 1980s, municipalities began to ban pallets from their landfills and increase tip fees. With over 95 per cent of pallets reused or recycled per year (2.4-million tonnes) and an annual industry growth rate of 18 per cent, the pallet business is one of Canada’s 3Rs success stories.
Without the wood pallet reuse and recycling industry, the success of NaPP — 51 per cent diversion by 1996 (baseline 1998) — would have never been achieved. (See “Caught NaPPing” in the October/November 1999 edition.)
Manufacturers of wood recycling equipment have capitalized on the situation. One leading company recently introduced an addition to its innovative line of horizontal grinders. Based on the highly successful HC 2400 Recycler series, Peterson Pacific Corp. of Eugene, Oregon has introduced the HC 2410 Heavy Duty Recycler. Track mounting on this grinder allows the operator to take the grinder to the material, which opens up grinding possibilities in previously inaccessible areas.
The HC 2410 is powered by a diesel engine rated at 460 horsepower and features a rotary drum grinder that has proven to be especially efficient at processing high moisture content organic material without plugging. Carbide bits mounted to fixed, non-swinging holders accurately size material. A horizontal feed conveyor works with a crushing feed roller to continuously and efficiently feed even bulky materials to the grinder.
The equipment is designed for processing organic material such as land clearing debris, construction debris and green waste. Product sizing is determined by an easy-access grate system, with a variety of grate sizes available.
Peterson’s horizontal grinders produce more output per hour than other machines in their horsepower class. HC 2410 testing has shown consistent production of up to 270 cubic yards per hour. All of the company’s grinders feature a totally enclosed grinding chamber which produces virtually no flying debris, making them far safer to operate than tub grinders.
