Anaerobic Digestion and its Sustainable Impact

Efficient management of organic waste is key to moving towards a more sustainable future. As a result, anaerobic digestion, also known as biomethanation, is emerging as an innovative solution that can turn organic materials into valuable resources. At Sun Chemicals Services, we are proud to present this process and explain its importance for the industry.

Anaerobic digestion is a biological process that occurs when no oxygen is present, in which micro-organisms break down organic materials to yield a combination of gasses, known as biogas. This biogas, which contains mainly methane and carbon dioxide, as well as other gasses in smaller proportions, is a valuable energy resource.

Anaerobic digestion entails breaking down organic material into simpler compounds, such as volatile fatty acids, by using micro-organisms. These acids are metabolised by methanogenic micro-organisms, generating biogas. This gas can be used as fuel for heating and/or electricity, helping reduce our dependence on non-renewable energy sources.

Digestates, the by-products of anaerobic digestion, have important potential as fertilisers. They can boost nutrient availability for crops and enrich soils with essential elements such as nitrogen, phosphorus and potassium, promoting healthy plant growth sustainably. Plus, they help close the nutrient cycle and reduce dependence on chemical fertilisers.

A biogas plant has two main outputs: biogas and digestates

Biogas can be used to generate electricity, while the digestate can be dehydrated and stabilised for use as fertiliser. It is important to note that these products are regulated by a specific regulatory framework, which ensures their quality and safety for use in agriculture.

At Sun Chemicals Services, we specialise in drafting the technical documents required for putting biogas plant substrates on the market as fertilisers. We offer full-service development of D1 modules, ensuring the quality of the production process for EU fertilisers. Our team of experts is committed to providing innovative sustainable solutions that help us advance towards a circular economy.

Anaerobic digestion and use of its by-products are an important step towards a more sustainable future. At Sun Chemicals Services, we are committed to leading this change, providing comprehensive solutions and specialised services that help build a greener, more prosperous world for future generations. Together, we are transforming waste into resources and having a positive impact on the environment.
