Ground-breaking green energy system utilises Polypipe’s Ridgistorm-XL

Posted: Friday 28th November 2014

Polypipe, the UK’s leading manufacturer of twin wall piping systems, has demonstrated the versatility of its Ridgistorm-XL large diameter pipe system by pre-fabricating an innovative, custom-made bio-reactor solution for a sports arena and its on-site accommodation.

Wheeldon Two, an off-road MotoX training centre in Devon, has invested in a revolutionary, new Anaerobic Digestion (AD) technology called Archemax® that will provide year round green energy, including heat and power to run the site’s indoor training arena and surrounding holiday cottages.

The owners of the centre required a cost-effective, carbon-neutral on-site unit that would deliver the majority of its energy requirements while creating no visual impact in what is an area of outstanding natural beauty.

Working closely with New Generation Biogas (NGB), the company that developed the Archemax® AD unit installed on the site, Polypipe was able to utilise the flexibility of its Ridgistorm-XL system to design and engineer four bio-reactors for the containment of agricultural waste, other organic matter and energy crops, with each unit measuring 2,100mm in diameter and 3,000mm high.

Biogas is generated when bacteria break down organic material in the bio-reactors, in a process known as anaerobic digestion. Biogas is a carbon-neutral renewable fuel, primarily methane and is used to fuel the CHP (Combined Heat & Power) plant, providing a reliable, sustainable and low cost source of hot water and electricity for the site.

Stirling Paatz, Director at NGB, said: “Biogas is very clean, efficient and environmentally-friendly, which complements our ethos on delivering products that are sustainable and carbon-neutral. It’s great that Polypipe shares our ideals and wanted to work with us on developing this pioneering project.

“We look forward to a long and harmonious working partnership with Polypipe as we build more Archemax® AD units for our customers.”

Mark Rowden, Emerging Markets Manager at Polypipe, said: “This is an exciting prototype project which we’re delighted to have been involved in. Our team worked closely with NGB to understand their specific requirements with regard to capacity, expansion, pressure and performance at high fermentation temperatures, thus ensuring that the project ran smoothly.

“The use of Ridgistorm-XL polyethylene structured wall tanks allowed our specialist product support team to assist with the installation of the bio-reactors and meant that on-site design changes could be made, allowing a high degree of flexibility in the development of the plant”.
