MEMBER PRESS RELEASE – Alps Ecoscience launches cost per tonne pricing for AD plant optimisation service

Environmental science provider Alps Ecoscience has launched a new range of Anaerobic Digestion (AD) specific managed services for 2021. These identify opportunities to improve biogas yields and raise capacity by increasing Organic Loading Rates (OLR) and balancing reactor biology.


Managing Director, Mike Platt said “The AD industry understands the cost per tonne model, so we have created a managed service that aligns. It includes sampling, lab work, catalysts, additives and ferric’s for digester balancing. Clients can see Alps inputs and measure the output in CH4 concentration, FOS/TAC and OLR rate. But most importantly they can measure the revenue increase daily on every tonne of waste.”


There are 3 tiers to Alps Ecoscience’s latest service, designed around an AD plants typical lifecycle. They are simply named Stablise, Optimise and Maintain.


Wade McRoberts, Alps Ecoscience Chief Technical Officer says, “performance volatility is a major issue for the AD industry, by focusing upon Hydrolysis we are consistently able to increase the overall rate of decomposition and balance FOS/TAC, resulting in increases to CH4 concentration and new capacity through higher organic loading rates (OLR). We are achieving similar results across many different plant configurations and feed stocks.


Alps Ecoscience say that in the past plant operators have been reluctant to commit to the fixed costs associated with innovations such as Digester Optimisation. However, with cost per tonne pricing the risk is shared and aligned to results. Operators can see the immediate impact of an optimisation programme on daily revenue. Recent results, from gas to grid plants show 5% higher methane concentration and 20%+ higher OLR. Commercially this equates to incremental revenue of over £100,000 pa. Detailed case studies are available, along with reference sites.
