Biogas Additives
Using the right additives in biogas plants is essential for enhancing environmental performance, operational efficiency, and financial returns.
Effective additives improve the breakdown of organic material, maximising biogas yield while reducing waste output. This increased efficiency lowers greenhouse gas emissions and minimises the need for additional feedstock, which contributes to a more sustainable and environmentally friendly operation. Financially, additives boost overall profitability by optimising gas production, cutting down on maintenance costs, and increasing equipment lifespan.
To maximise efficiency in biogas plants, several key goals should be prioritised:
-
Optimising Biogas Yield: Maximising gas production from available feedstock is crucial. This involves selecting and pre-treating substrates to increase microbial breakdown, using additives to enhance digestion, and maintaining an ideal mix of feedstock for stable, consistent gas production.
-
Maintaining Process Stability: Biogas production is sensitive to pH, temperature, and nutrient balance. Maintaining these factors within optimal ranges helps prevent process disruptions and ensures a stable environment for methane-producing bacteria, which directly affects biogas output.
-
Reducing Maintenance and Downtime: Keeping equipment clean and functioning smoothly minimises downtime. Regular monitoring and preventive maintenance, alongside the use of anti-corrosion and anti-foam agents, help extend equipment life and reduce the risk of costly repairs or replacements.
-
Minimising Waste and Emissions: Efficient biogas plants reduce waste by converting more organic matter into biogas, resulting in lower emissions of methane and other greenhouse gases. Effective waste management also reduces odors and improves the plant's environmental impact.
-
Increasing Financial Return: By maximising gas yield, reducing operating costs, and improving system reliability, biogas plants can enhance profitability. This includes optimising energy recovery for use on-site or for sale, which directly improves the plant's economic viability.
In this FAQ section, we’ll cover the key benefits and considerations for choosing the right biogas additives to help you get the most out of your plant.
OLIGAS trace elements are a customised blend of essential trace elements, carefully formulated to support the specific needs of your digester. They play a crucial role in enhancing microbial resilience and maintaining stable biogas production. By supplementing the digester with these tailored trace elements, OLIGAS helps achieve two main objectives:
-
Strengthening Microbial Health: The added trace elements make the microbes in your digester more robust, ensuring a smoother, more consistent production of biogas. This stability helps prevent sudden drops or "crashes" in gas output, even when operational demands fluctuate.
-
Increasing Feedstock Flexibility: OLIGAS enables the safe use of challenging feedstocks, like poultry litter and other high-nutrient materials that might otherwise disrupt the digester’s balance. This flexibility opens up new possibilities for feedstock choice, increasing efficiency and potentially lowering input costs.
With these benefits, OLIGAS trace elements not only help optimise biogas yield but also contribute to a more resilient and cost-effective digestion process.
METHOgas is a patented additive that harnesses the power of electrically charged polyamines to boost the efficiency of your digester. By enhancing enzyme activity, METHOgas supports the breakdown of fibrous materials, allowing for a more thorough digestion process. This not only improves fiber digestion but also stimulates methanogenic bacteria, leading to increased gas production.
With METHOgas, you can achieve greater biogas output by maximising the digestion of feedstocks, contributing to a more efficient and productive biogas system.
METHOFILTER is an innovative alternative to activated carbon for removing hydrogen sulphide from biogas. One major advantage of METHOFILTER is its recyclability within the digester: instead of incurring disposal costs, you can simply add the used METHOFILTER back into the biomass feeder. This approach not only eliminates disposal expenses but also allows for the recovery of any remaining active components, reducing the need for additional iron supplementation.
Yes, in fact it’s even safe to operate a digester using only poultry litter as a feedstock. With the right products and expert guidance, you can significantly increase the proportion of high-nitrogen materials like poultry litter without the need for costly ammonia extraction technology. Our solutions are designed to help stabilise the digestion process, making it efficient and manageable, even with challenging, nitrogen-rich feedstocks.
