Product Focus

The Environmental & Reduction Equipment Council serves the needs of AEM member companies who manufacture high-speed grinders (horizontal & tub), stump grinders, whole tree chippers, brush (hand fed) chippers, mulching attachments, flail delimber/debarker machinery, and low-speed shredders.


The Council aids machine manufacturer efforts to meet the safety and productivity needs of material reduction equipment operators and owners.

Bureau Activities

The group, formed in 2013, addresses issues of interest to member manufacturers of size reduction equipment and their major component suppliers. This includes technical and safety topics, advocating with Standards Development Organizations (SDO's) in North America and Worldwide on standards issues, advocating with government agency rulemaking processes, and working in other issues of interest to the member firms and their machine operators/owners.

Some current projects are:

  • Operator Safety Manual for handfed (brush) chippers.
  • An Operator Safety Manual for high speed grinders - work underway
  • An Operator Safety Manual for mulching machinery - in queue.
  • Through an ad hoc committee, propose needed safety pictorial graphics for decals,  for machine fed (whole tree) chippers, for high-speed grinders, and for handfed chippers.  Finished graphics will be added to AEM's Safety Pictorial Database.
  • Support of ISO TC23/SC15 US Technical Advisory Group (US TAG) work developing new standards for machine fed chippers, horizontal/tub grinders, and mulching equipment.
  • The study of options available to eliminate or reduce the hazard of thrown objects from chipping, grinding, mulching, and debarking equipment, and prepare industry consensus machine operating best practice documents.

The EREC meets in person twice each year, with online meetings held if needed at other times.  Usually meets in conjunction with AEM's Forestry Equipment Council, and/or ISO TC23/SC15 Standards Groups (US Advisory, or International Plenary meetings).

Organized as an AEM Product Council in 2013.
