Every animal produces waste. An average person generates around 0.2 kg of waste per day, while a dairy cow can produce approximately 30 kg of manure every day.

At small scales, manure can be a valuable fertilizer. At larger scales, however, excess manure can contribute to methane emissions, water pollution, and nutrient overload in rivers and ecosystems.

Today, farmers and scientists are exploring new ways to transform manure from a challenge into an opportunity. Through technologies such as anaerobic digestion, manure can be converted into biogas, a renewable energy source that can generate electricity, heat buildings, or power farm operations.

The remaining material can be processed into nutrient-rich fertilizer, helping to close the loop between food production and soil health.

A herd of 100 dairy cows can produce nearly 3 tonnes of manure every day.

The future of agriculture is not only about producing food. It is also about finding smarter ways to use resources that were once considered waste.
