Powered by Plants: Sainsbury’s Switch to Eco Energy

Published

on

Leading supermarket chain Sainsbury’s have teamed up with the UK’s biggest food waste recycler ReFood. Together they are turning Sainsbury’s supermarkets eco-friendly by powering them using only green gas. The partnership has been hailed as one of the largest of its kind in the UK.

In partnership with the UK’s leading food waste recycler, ReFood, a number of Sainsbury’s supermarkets across the country are now powered by green gas. Produced entirely from waste food, the energy generated over the past year alone is enough to power 5,000 homes, or 10 per cent of Sainsbury’s entire national gas consumption for the year, with ReFood having supplied the retailer with almost 50 million KWh of biomethane gas to date.

As part of the agreement, food waste is collected from Sainsbury’s’ two depots in Sherburn-in-Elmet and Haydock, before being converted into gas, heat and fertiliser at ReFood’s state-of-the-art anaerobic digestion (AD) processing facilities.

The green gas is then exported to the national gas grid by ReFood and, through a third party, is imported by Sainsbury’s stores nationwide – being used to generate carbon-neutral electricity for power and heating. The agreement is one of the largest of its kind in the UK, seeing ReFood supplying both green gas and supporting certification.

As a result of the partnership, ten stores have already significantly increased their use of renewable energy, while lowering utility bills. The partnership also helps to deliver Sainsbury’s commitment to send zero operational waste to landfill, by finding a use for inedible waste products. All surplus edible food is donated to local charity partners.

Paul Densham, Utilities Buyer at Sainsbury’s, said: “Increasing the sustainability of our UK stores is a key corporate priority and we’re making great progress in our drive to reduce food waste across the business. Working in partnership with ReFood allows us to effectively recycle our food waste, creating renewable energy in result.

“What’s more, it sits well alongside our wider sustainability goals, such as working with food redistribution charities and prioritising sustainable transport strategies. The project has helped us to become a market leader in sustainability and waste reduction, ensuring that we send zero waste to landfill – a promise we’ve been able to make for some years now.”

Philip Simpson, Commercial Director at ReFood, added: “Using our national network of processing plants, we’ve provided a truly sustainable solution for stores across the UK.

“Generating a significant volume of green gas in result, the partnership has enabled Sainsbury’s to use less fossil fuels, minimise utility bills and eliminate unnecessary food waste disposal. What’s more, with a highly effective sustainable biofertiliser also generated via the AD process, stores nationwide are working together to effectively close the food supply chain – from farm to fork and back again.”

Anaerobic digestion is a natural process where organic materials are broken down by naturally occurring micro-organisms. This releases biogas that can be used to generate renewable heat and power, helping to reduce dependence on fossil fuels, while minimising greenhouse gas emissions.

Most of our focus on technological development to lessen our environmental impact has been focused on cleaner, more efficient methods of generating electricity. The cost of solar energy production, for example, is slated to fall more than 75 percent between 2010 and 2020.

This is a massive step forward, and it’s good that engineers and researchers are working for even more advancements in this area. But what about technologies that reduce the amount of energy we demand in the first place?

Though it doesn’t get as much attention in the press, we’re making tremendous progress in this area, too.

New Technologies to Watch

These are some of the top emerging technologies that have the power to reduce our energy demands:

  1. Self-driving cars. Self-driving cars are still in development, but they’re already being hailed as potential ways to eliminate a number of problems on the road, including the epidemic of distracted driving ironically driven by other new technologies. However, even autonomous vehicle proponents often miss the tremendous energy savings that self-driving cars could have on the world. With a fleet of autonomous vehicles at our beck and call, consumers will spend less time driving themselves and more time carpooling, dramatically reducing overall fuel consumption once it’s fully adopted.
  2. Magnetocaloric tech. The magnetocaloric effect isn’t exactly new—it was actually discovered in 1881—but it’s only recently being studied and applied to commercial appliances. Essentially, this technology relies on changing magnetic fields to produce a cooling effect, which could be used in refrigerators and air conditioners to significantly reduce the amount of electricity required.
  3. New types of insulation. Insulation is the best asset we have to keep our homes thermoregulated; they keep cold or warm air in (depending on the season) and keep warm or cold air out (again, depending on the season). New insulation technology has the power to improve this efficiency many times over, decreasing our need for heating and cooling entirely. For example, some new automated sealing technologies can seal gaps between 0.5 inches wide and the width of a human hair.
  4. Better lights. Fluorescent bulbs were a dramatic improvement over incandescent bulbs, and LEDs were a dramatic improvement over fluorescent bulbs—but the improvements may not end there. Scientists are currently researching even better types of light bulbs, and more efficient applications of LEDs while they’re at it.
  5. Better heat pumps. Heat pumps are built to transfer heat from one location to another, and can be used to efficiently manage temperatures—keeping homes warm while requiring less energy expenditure. For example, some heat pumps are built for residential heating and cooling, while others are being used to make more efficient appliances, like dryers.
  6. The internet of things. The internet of things and “smart” devices is another development that can significantly reduce our energy demands. For example, “smart” windows may be able to respond dynamically to changing light conditions to heat or cool the house more efficiently, and “smart” refrigerators may be able to respond dynamically to new conditions. There are several reasons for this improvement. First, smart devices automate things, so it’s easier to control your energy consumption. Second, they track your consumption patterns, so it’s easier to conceptualize your impact. Third, they’re often designed with efficiency in mind from the beginning, reducing energy demands, even without the high-tech interfaces.
  7. Machine learning. Machine learning and artificial intelligence (AI) technologies have the power to improve almost every other item on this list. By studying consumer patterns and recommending new strategies, or automatically controlling certain features, machine learning algorithms have the power to fundamentally change how we use energy in our homes and businesses.

Making the Investment

All technologies need time, money, and consumer acceptance to be developed. Fortunately, a growing number of consumers are becoming enthusiastic about finding new ways to reduce their energy consumption and overall environmental impact. As long as we keep making the investment, our tools to create cleaner energy and demand less energy in the first place should have a massive positive effect on our environment—and even our daily lives.
