Food waste fuels mushrooming of thriving Scots power sector

Published

on

Scotland’s anaerobic digestion industry – which turns rotting food and farm waste into electricity – has mushroomed by more than two thirds in a year, new figures show. Twenty seven AD projects are up and running in Scotland, up 69% (from 16) in 12 months ago, while a further 43 have planning approval.

With a dozen more plants waiting for permission to go ahead, the sector could grow by more than 200% in the next two years, figures from the Anaerobic Digestion and Bioresources Association (ADBA) show.

The AD process involves farm slurry, vegetable peelings, paper and other organic material decomposing inside a closed chamber to produce gas, which is then used to generate electricity.

The amount of food thrown away in Scotland each year has fallen by 8% since 2009, while less than half of Scotland’s household waste was sent to landfill in 2014 – the first time that figure has ever dipped below the 50 per cent mark, and a sign that technology like AD can help reduce demand on landfill space.

Increased numbers of household food waste collections under by the Waste (Scotland) Regulations 2012 mean more will become available to fuel Scotland’s ongoing AD boom.

Stephanie Clark, Policy Manager at Scottish Renewables, said: “These new ADBA figures show that AD is being taken extremely seriously by Scottish businesses.

“Increasingly, waste has value. The AD process recognises that, and turns things we don’t want, like food waste and farmyard slurry, into something we desperately need – clean, affordable electricity.”

Charlotte Morton, Chief Executive of ADBA, added: “Scotland is leading the way in demonstrating how anaerobic digestion extracts value from our waste, while supporting farming resilience, reducing billions in carbon abatement costs, improving food security and production and generating employment and investment opportunities for rural economies.

“We are particularly excited to see AD plants working in partnership with local authorities to collect residents’ food waste and to distribute in its place heat and electricity for local homes.

“Developments in Scotland are now being used to showcase the excellent return on investment that bill payers gain from the continued deployment of AD capacity. With a commitment from government to support the technology to scale – a commitment which currently does not exist – AD can deliver baseload energy that is cheaper than new nuclear by the time Hinkley Point C is built, and that can help decarbonise UK heat, farming and transport.”

Farmers Use Ad To Make Power From Pig Waste – BioGask’s AD plant near Turriff, Aberdeenshire

BioGask, based at Gask Farm near Turriff, Aberdeenshire, uses an anaerobic digestion system to dispose of food waste and slurries for commercial customers. Currently, pig slurry and meat processing waste are fed into a 2,500 cubic metre tank where, under in the absence of oxygen, bacteria will breakdown the material and produce a methane-rich gas which can be used to make electricity.

The AD plant at BioGask also has the potential to use chicken feathers, maize silage and fish processing wastes to produce power. Owner Andrew Rennie said: “The AD plant allows local businesses to dispose of their waste in a safe and controlled way, and in a way which not only produces electricity which can be sold to the grid, but also a fertiliser which can be used on the land.”

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.
