Sustainability is a core value and operational philosophy. Milorganite's parent company the Milwaukee Metropolitan Sewerage District (MMSD) focuses on products, processes and services to preserve the natural environment through the reduction of consumption, waste and emissions. MMSD promotes, through policy, the optimization of renewable energy, the reduction of emissions from fossil fuels, recycling and the use eco-friendly materials. MMSD is leading the nation in Green solutions and has transformed its approach to water management.
Natural Organic Material
Milorganite is composed of natural organic material. Unlike “man-made” synthetic products, Milorganite is not dependent on the petroleum industry.
85+ Years of Recycling
The microbes that make up Milorganite are a natural by-product of wastewater treatment. Some communities choose to landfill this useful material. Instead, Milwaukee safely re-purposes the microbes and allows consumers to make use of the valuable growing power in Milorganite. We’ve been recycling for over 85 years, making us the nation’s oldest recycler.
Bio-Preferred - USDA Certified
Milorganite is certified by the United States Department of Agriculture (USDA) as a biobased product because it is derived from renewable materials. The USDA BioPreferred program qualifies products as biobased if they are “composed wholly or significantly of biological ingredients-renewable plant, animal, marine or forestry materials.” Fertilizers are tested for biobased content by a third-party lab and then deemed certified by the USDA. Look for the certified biobased label to identify these products to help select products that reduce environmental impact and are proven to be more environmentally friendly.
While synthetics rely on fossil fuels as a key input in the manufacturing process, Milorganite continues to explore alternative energy sources. One example is a landfill gas project launching in 2014. This development will reduce our natural gas needs by piping in pre-treated landfill gas to generate the majority of our energy for the next 20 years in a sustainable manner. This project fits with our mission of creating value where others see waste, and will lessen the impact of production on the environment.
