EN Engineering Provides Array of Services for Revolutionary Feedstock Evaluation Unit

September 26, 2019

(Warrenville, Illinois) As mentioned in Newsweek and Bloomberg Businessweek today, EN Engineering, as part of the Engineering, Procurement, and Construction (EPC) team led by Denham-Blythe Company (Lexington, Kentucky), provided multi-discipline engineering, permitting, and process safety management services to PureCycle Technologies, Inc. (Chicago, Illinois) for their Feedstock Evaluation Unit (FEU). PureCycle Technologies just announced it has successfully purified waste carpet, transforming discarded carpet into clear, odorless, ultra-pure polypropylene (UPRP) resin at their FEU located in Ironton, Ohio. The Denham-Blythe/EN Engineering team was responsible for the design-build delivery of all site, architectural, and utility system components. The FEU utilizes a groundbreaking, patented process developed by Procter & Gamble which purifies polypropylene resin, a material which makes up a large percentage of recycled plastics commonly found in diapers, rope, carpet fibers, retail food and beverage containers.

“The plant is the first of its kind to remove color, odor and impurities from waste polypropylene, producing virgin-like resin to be used in consumer goods packaging, home furnishings and other applications that currently have very limited recycled PP options today,” explained Steve Knowles, CEO, EN Engineering. “Working with a brand new technology presents unique challenges, and our team demonstrated flexibility and skill in addressing process modifications quickly.”

“By working together with a focused approach, we can clean up the planet,” stated PureCycle Chief Operations Officer Tayt Rule. “We’ve had a great experience working with the EN Engineering and Denham-Blythe team for our Feedstock Evaluation Unit. Because of our track record of success together, we are even more excited to be working with this team for construction on our commercial plant.” Within the next 30-60 days, the teams will begin work on a larger-scale, commercial-sized polypropylene resin purification facility on the same site, which will process 105,000,000 lbs. per year of recycled polypropylene.
