Focused on beneficial reuse, GSI's treatment of organic waste produces high quality finished compost that is sold in bulk and bagged format for horticultural and landscaping uses. The bulk soils produced have earned us the highest marks from the landscape architecture community and green space maintenance experts.
Some of our products are targeted toward the agricultural market: these include amendments and alternative organic fertilizers. The latter have various origins, including pulp and paper mills and municipal treatment plants and the availability of each amendment and fertilizer varies in each region depending on the generators of the residue.
