ALPS Ecoscience offer a comprehensive range of anaerobic digestion optimisation services tailored to support every aspect of the anaerobic digestion process. Our multidisciplinary team of experts employs the latest innovations and best practice to deliver superior results for all feedstocks and plant configurations.

Optimising Microbial Health

The microbial community is the engine of anaerobic digestion. Our services include microbial health assessments, inoculum management, and tailored interventions to maintain a thriving microbial ecosystem. By ensuring optimal conditions for microbial activity, we enhance the overall efficiency and stability of your AD process. Learn more…

Maximising Feedstock Potential

Pre-treatment of feedstock is critical for maximising biogas yield. We offer mechanical, thermal, and chemical pre-treatment solutions that increase the biodegradability of your feedstock. These methods break down complex organic materials into simpler forms, enhancing the efficiency of the digestion process and boosting methane production. Learn more…

Enhanced Digestion Efficiency

Advanced anaerobic digestion technologies, including single and multi-stage systems, offer superior performance. Single-stage AD is suitable for simpler feedstocks and lower investment costs, while multi-stage AD systems separate the hydrolysis, acidogenesis, and methanogenesis stages, allowing for more controlled and efficient digestion. Our expertise in both approaches ensures that you receive the best possible system tailored to your specific needs. Learn more…

Sustainable Nutrient Management

Efficient nutrient recovery from digestate not only enhances the sustainability of your operations but also adds economic value. We provide cutting-edge solutions for recovering valuable nutrients from the digestate, transforming waste into resources and minimising environmental impact. Our nutrient recovery systems ensure that your biogas plant operates in a circular economy framework. Learn more…

1     Optimisation methodology

The optimisation strategy is site specific and determined by the commercial objectives. It will therefore include some or all the following services to progressively build plant performance step by step.

1.1       Biological process engineering

This is starting point of all optimisations and is driven from the lab tests and site data analysis. ALPS will identify immediate gains available through adaptions. The aim is to achieve a stable biology and consistent output as a platform from which to enhance the conversion efficiency and maximise the available production capacity. ALPS will prepare a strategy and implementation plan, deploying one of our consultants to deliver to work packages with the site operating team.

1.2       Performance boosting additives, nutrients & chemicals

Having achieved a stable baseline ALPS will then test to determine whether the digesters would benefit from additional trace elements, catalysts, or enzymes. These are assessed at bench scale to determine efficacy and dose rate after which containers of the additive are delivered and installed with dosing equipment by an ALPS technician as part of our managed service.

1.3       Digester re-configuration (single/multi-stage/SMASH)

Once maximised production efficiency is realised from existing infrastructure, the question arises whether to upgrade the plant infrastructure to unlock additional capacity. ALPS help clients review the options based on our understanding of the feedstocks and the desired commercial operating model. The wealth of data built up through our managed service support provides an empirical base from which to model the options and then replicate the optimal solution in a pilot setting. This de-risks strategic decision making when upgrading to advanced AD technologies such as SMASH.
