Food and drink manufacturers are making CHP work for them, find out how.
With a turnover of £92bn (including exports of £19bn - £14.4bn to Europe), food and drink (F&D) manufacturing is the UK’s largest manufacturing sector.
To help meet the Food and Drink Federation’s (FDF) target for sustainable growth of 20% by 2020, the following 5 F&D manufacturers have already recognised the main benefits of investing in Combined Heat and Power (CHP).
Adams Foods, Leek
At their new state-of-the-art cheese packing facility, the dairy products company world famous for Kerrygold butter, have installed a CHP system to generate reliable energy supplies.
The unit produces:
- 150 kW of electricity.
- 225 kW of heat - used for pre-heating washing and cleaning water.
Operating 24 hours a day, the 15,500m2 site has been achieving carbon savings of 476 tonnes per annum, equivalent to an environmental benefit of 47,600 trees.
Adams Foods have also implemented a number of other energy saving measures to help future proof the CHP system.
Tangerine Confectionery, Pontefract
The leading UK independent manufacturer of sugar confectionery (including Butterkist popcorn) are using two energy efficient CHP systems at their production plant.
- 500 kW Cogeneration providing electricity and heat energy.
- 230 kW Trigeneration providing site with electricity, heating and cooling.
The facility will benefit annually from:
- Carbon savings of 630 tonnes (equivalent to 63,000 trees).
- Cost savings £200,000.
The global fizzy drinks brand are planning a world-wide installation of CHP at 20 sites by 2015.
Having installed CHP at bottling plants in the USA, Italy and Northern Ireland, Coca-Cola are also planning a CHP at their site in Wakefield, which is the largest soft drinks plant in Europe.
Target: to cut the site’s greenhouse gas emissions by 5.6%, with carbon savings of 1,500 tonnes per annum.
McCain Foods, Whittlesey
In addition to using biogas to fuel its steam boilers, the well-known manufacturer of potato-based products also runs its CHP on biogas produced from the site’s anaerobic digestion (AD) treatment lagoon.
The 1 MWe CHP provides 10% of the site’s electrical load and the heat energy is used to warm the lagoon.
Other companies are considering the combination of CHP with AD to accumulate further savings by using fuel produced from site waste.
North British Distillery, Edinburgh
A 500 kWe CHP system and 1,000 kW steam boiler have been installed alongside the new AD plant at the whisky distillery, which is world-famous for producing Famous Grouse and Johnnie Walker Black Label.
CHP’s main benefits to F&D manufacturers:
- Saves energy and reduces energy costs.
- Almost twice as efficient as conventional energy generation.
- On-site generation provides more reliable and secure energy supplies.
- Reduced greenhouse emissions offsetting the impact of Carbon Reduction Commitment (CRC).
- Avoids Climate Change Levy (CCL).
- Qualifies for government incentives – eligibility for Enhanced Capital Allowances and reduced tax liabilities.
