Tub grinders were first introduced during the 80's for wood and green waste recycling applications. They were originally designed to recycle logging slash and lumber mill waste by reducing the waste wood into boiler fuel.
Tub grinders are primarily built to handle wood and green waste material such as bark, brush, logs, leaves and compost can be reduced or recycled into a salable, valuable, usable products. Mulch, colored mulch, boiler fuel and compost are just a few of the finished products produced by tub grinding. Some tub grinder owners use them to reduce the volume of their material to minimize trucking and save on dump or tipping fees.
