AlzChem tests Eminex manure additive with Uelzena on four dairy farms

AlzChem's product Eminex®, a manure additive, is being tested in a pilot project started at the end of 2025 with Uelzena eG and four dairy farms to reduce methane emissions from slurry storage. Farms reported less foam, more uniform slurry, better use of storage capacity, shorter stirring times before spreading, and reduced odour in barns. The learnings are to be systematically evaluated and, if successful, transferred to more farms across the dairy supply chain.

Key facts

Market context

Manure additives are chemicals added to livestock slurry in storage tanks or lagoons to change how the material behaves. Slurry from cattle and pigs releases methane, a potent greenhouse gas, as it decomposes anaerobically, and treatments that reduce this release are of growing interest to farmers and the food companies that buy their milk. Demand for such products is driven mainly by dairy and livestock farming, where operators face pressure to meet emissions targets, improve barn air quality and manage storage capacity. Dairy processors and cooperatives are increasingly looking at emissions along their raw milk supply chains, which means on-farm measures can become part of contracts and sustainability reporting. For chemical suppliers, a shift from trial projects to broader adoption would open a new application area beyond traditional agricultural inputs, although the market remains early and its size depends on documented results and farmer uptake.
