HWI Environmental Technologies, Inc12951 Gravois Road Suite 110 , St. Louis, Missouri, United States

HWI was founded in 1993 to provide alternative treatment and recycling options for generators of hazardous waste. Hazardous waste disposal was only the beginning. HWI quickly saw a need to develop a program that encompasses all facility waste streams. So in 1996, HWI developed our comprehensive on-site waste program that covers options for your waste streams including recycling and beneficial reuse for all by-products generated at your facility.  This new broader vision led to the inception of our recycling equipment sales and service division. 

Over the years HWI has won many environmental awards for our clients. The reason for this success is that we are a non-biased third party.  HWI supplies the labor, equipment and material outlets needed to make your facility's waste program environmentally, financially and operationally sustainable.

Today HWI is a fully integrated waste and by-product management company. We are a nationally certified woman owned business (WBE) that offers nationwide service.

HWI's core staff collectively brings over 87 years of experience to the waste and recycling field. Our compliance department is led by a licensed Professional Environmental Engineer and Registered Environmental Manager. Our traffic and shipping staff take care of transportation issues so you don’t have to waste valuable time. HWI's research department creates options and makes sure we bring home the results you need. Our equipment division services your equipment 24/7 and defines optimal equipment solutions to meet your exact needs and budget.
