Heat exchangers are a well established tool for the thermal processing of materials. They are used for cooking, pasteurisation and sterilisation, as well as for heating or cooling a range of products. When it comes to designing a heat exchanger, there are two main considerations. The first is to select the right type of heat…

HRS Heat Exchangers is supplying the pasteurisation technology for a new anaerobic digestion (AD) plant in the south of France, which, once operational, will convert more than 65,000 tonnes of abattoir and agricultural waste products into electricity, useful heat and a valuable biological fertiliser for use by local farmers. The plant is being developed for…

The scientific consensus on climate change is now well established. 2016 was the warmest year on record, and it is clear that in order to avoid the very worst effects of climate change, we need to use every available tool to decarbonise as many aspects of society as possible, from energy generation and transport, through…

By Matt Hale, International Sales Manager, HRS Heat Exchangers With a few notable exceptions, such as new US president Donald Trump and our own Nigel Lawson, the scientific consensus on climate change is well established. As far back as 2004, 75%[1] of US scientific papers accepted the premise of human modification of the climate. Today,…

By Matt Hale, International Sales Manager, HRS Heat Exchangers In the UK, the wastewater treatment sector has used both aerobic and anaerobic treatment for many years. It is therefore not surprising that when the Renewables Obligation (RO) was introduced in April 2002 (April 2005 in Northern Ireland), sewage sludge anaerobic digestion (AD) plants were well…

Sustainability has never been higher on the agenda for food and drink companies than it is now. Not only does operating in an ethical and environmentally responsible way make sense for both planet and pocket, but it’s clear that this is what consumers want, too. Research from Globescan revealed that 92 percent of shoppers think…

Whether to add pasteurisation to an anaerobic digestion plant can be a contentious topic in certain circles. While there are undoubtedly benefits, including compliance with the PAS 110 standard for digestate, many plant operators and those considering biogas project see pasteurisation as adding unnecessary cost and complexity to the process.   However, six years of…

HRS Heat Exchangers are proud to announce our recent alliance with the recently launched  World Biogas Association (WBA). With a key focus on managing energy efficiently across the Anaerobic Digestion sector, HRS has partnered with the WBA as founder members to help the association to further develop growth and sustainability across the international AD community….

HRS India has successfully supplied Nagarjuna Fertilisers with a bespoke thermal transfer solution to overcome a challenging fertiliser production application in India. Nagarjuna Fertilisers are one of the most recognised agricultural brands in India and manufacture a broad range of speciality fertilisers to the farming sector. Energy efficiency in terms of quantum and cost is…

Anaerobic digestion (AD) produces many valuable and useful products, including biogas (which can then be turned into heat, electricity or biomethane gas) and digestate, a biofertiliser rich in nutrients and organic matter. However, many AD plants also produce incidental heat, which can be captured and used within the AD process or for other on-site operations….
