With an enviable reputation in tank storage knowledge and technical expertise, tank breather valves have always been a core product supply for Assentech. With increased focus on the environment and the risks associated with emissions from the biogas and chemical industries, our mission is to support operators with measuring, monitoring and reducing plant emissions to demonstrate best practices, and evidence a duty of care to the workforce and environment. By using a Best Available Technique (BAT) to identify leak points, ie, breather valve leakage, is key criterion for Regulation 61 compliance and supporting the biogas industry to reach Net Zero. The failure to mitigate risks impacts so many departments of any business, ie, legal, quality, environmental, engineering, procurement, finance and insurance.
Over 80% of the valves installed from new or maintained at tank storage facilities have not been supplied with a leak test certification and aligned to the international standards – API2000 / ISO 28300. It’s not surprising that environmental breaches, criminal investigations and litigation claims have increased for excessive emissions and the failure by tank storage facilities to mitigate risk and demonstrate a responsibility to prevent exposure.
With individual breather valves being uncertified (ie not tested in accordance to the test protocol of API2000), valves leaking at the digester’s operating pressure ranges from 4-50 cubic feet per hour (CFH) you can understand the impact this is having on operating profits, the environment and the health staff and neighbours working in close proximity to the site. Please take a look at our emission calculation programme below to understand the financial, environmental and safety risks associated.

The Environment Agency, ADBA and many other committees and organisations routinely request input from Assentech in the development of best practice guidance for operators in the tank storage and biogas industries.
Our Service Engineers have amassed an extensive array of knowledge and practical experience dealing with a diverse range of breather valve applications. This spans from biogas digesters and chemical storage facilities to pharmaceutical operations and oil and gas industries. We boast a profound understanding of the entire application spectrum, recognising the implications of fill/empty rates and the accurate designation of valve set pressures. Our expertise enables us to optimise operating pressures and curtail emissions, thereby ensuring the maximum efficiency and sustainability of your operations.
Emissions Case Study
We can supply, test and calibrate valves that will keep your Biogas facility safe, compliant and profitable by ensuring valves are individually tested on the pressure and vacuum ports and meet the acceptable leakage rate to less than 0.1 CFH.
To demonstrate both the financial and environmental impact of breather valve leakage, our Engineers recently attended a biogas facility and reduced leakage/emissions from one 12” breather valve from 161 tonnes GWP to just 158 kg per year (equivalent to 118 double-decker buses to 11% of one) by using best available techniques of ageing plant.
