Waste composition studies provide invaluable information for assessing current and future programs, but must be conducted properly to provide accurate data. Green Solutions has a proven track record for conducting such studies successfully.

Related Work

Green Solutions has also been involved in designing new approaches and training others to conduct studies, as well as testing the composition of recyclables and mixed organics.  Green Solutions is currently conducting a project for the City of Seattle and King County to audit the performance of construction waste recycling facilities.  Previously, Green Solutions assisted the City of Portland with tests to determine the feasibility of collecting food scraps and reducing garbage collection to every-other-week. 

cost-effective results

Providing accurate results on the breakdown of a waste stream can be a substantial investment, but there is no replacement for real data.  Green Solutions can generally conduct waste composition studies at half the cost or less compared to other consultants.  We can also work with clients to employ local labor or jointly explore other cost-cutting measures.  Don't hesitate to call us if you have any questions about what we can do for you.  Contact Rick Hlavka at (360) 897-9533 or at rick@green-solutions.biz.
