A tree chipper or woodchipper is a machine used for reducing wood (generally tree limbs or trunks) into smaller woodchips. They are often portable, being mounted on wheels on frames suitable for towing behind a truck or van. Power is generally provided by an internal combustion engine from 3 horsepower (2.2 kW) to 1,000 horsepower (750 kW). There are also high power chipper models mounted on trucks and powered by a separate engine. These models usually also have a hydraulic crane.

Waste is inevitable in any construction or development project. Whether it’s clearing and grubbing, new construction and building, improvements to infrastructure, or demolition, waste is the deliberate or indirect result of these operations. Clearing and grubbing operations produce large quantities of a homogenous waste (a.k.a. green waste).

“If you go to the basic biology of it, there are two basic principles,” says Mark Fiely, horticulturist at Ernst Conservation Seeds. “The new roots lock the soil in place and the leaves reduce the velocity of the rain.” Fiely always recommends planting diverse species.

When Green Turns to Gold

About one-third of municipal solid waste in the United States is organic, including foodwaste, yardwaste, and woodwaste. Some 65% of yardwaste and 2.5% of foodwaste in the US is now being diverted from disposal. According to the USEPA, converting waste into valuable raw materials through recycling creates jobs, builds more

Sustainable Shredding

Grinders and shredders in North American MSW operations are generating revenues through the creation of everything from landscape mulch to waste-to-energy fuel, as the latter market takes an increasing foothold in the United States. More than a year ago, Lindner Recyclingtech set up a subsidiary in Raleigh, NC, to address

Rethinking Sustainable Organics

We currently use over a third more resources a year than our planet can sustain. This now has affected not only our ecological environment, but also the platform where our economy stands. “Sustainability” appears to be a term that is merging environmental science with economic principles. John Skinner, the executive

Resourceful With Waste

Successful grading and excavating contractors are, if anything, resourceful when it comes to meeting a challenge. The worst recession in memory for most of them has highlighted the value of making the most of every available resource. Those resources include materials once considered a costly disposal problem—such materials as stumps,

Business Diversification Tools

As any grading and excavation contractor who’s ever operated an excavator or skid-steer knows, more than just dirt often needs to be displaced. Typically, trees, roots, rocks, concrete, or steel—or all of the above—must be cleared to make way for a hole or subgrade. These additional materials present an opportunity
