In gardening, clipping is equivalent to pruning, the practice of removing diseases, overmature or otherwise unwanted portions from a plant. Clipping typically involves much less removal than pruning, and is used more for herbaceous (all-green) plants than for woody ones.

Biofuels

Main article: Cellulosic ethanol

In addition, BlueFire Ethanol Fuels, Inc. has been granted a conditional-use permit from the County of Los Angeles for the construction of a commercial facility to convert biowaste into ethanol. To be located near Lancaster, about 45 miles north of Los Angeles, the facility will use concentrated acid to break down non-foodstock urban wastes (such as grass clippings) and forestry and agricultural residues so they can be fermented into ethanol. Slated to begin operation in late 2009 with partial funded from a DOE grant, the facility will separate lignin from the biomass and use it to produce electricity and steam .
