Abstrakt:	The article focuses on Groundscapes Express Inc. owner John Engwer's use of mulch-blowing trucks in making composts, topdressing lawns, and amending soils in Wrentham, Massachusetts. Engwer worked with the state in a joint venture to site a compost operation, and set up a commercial-scale composting operation. The author further highlights the facility's utilization of local food and yard waste while avoiding biosolids which may contain contaminants such as heavy metals.
