1. Milorganite uses alternative energy sources such as solar, landfill gas, and digester methane.
2. The Milwaukee Metropolitan Sewerage District (MMSD) is leading the nation in "Green" solutions.
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. The 2035 vision is to have 80% of our energy needs supplied from renewable sources. 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 byproduct 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.
While synthetics rely on fossil fuels as a key input in the manufacturing process, Milorganite continues to explore alternative energy sources such as solar, digester methane, and landfill gas to run its operations. Our landfill gas initiative, launched in 2014, is reducing our dependence on natural gas and electricity from the grid, by piping in pre-treated landfill gas to generate the majority of our energy for the next 20 years. This project fits with our mission of creating value where others see waste, and will lessen the impact of our operations on the environment.
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
