Drax Power ‘to target garden waste’ for burning

Organic waste, including wood and garden wastes, from the UK are going to become an enormous part of the feedstock used by Drax Power in the future, Dorothy Thompson, the operators chief executive, has predicted, writes Steve Eminton.

Speaking at Poyry Management Consultings seventh annual Forest Industry event on May 6, 2011, Mrs Thompson, chief executive of Drax Power Ltd, said: “We are aiming to become the biggest biomass plant in the world. We have eight years of experience burning biomass at Drax and have developed a sustainability standard at Drax for everything that is built.”

Mrs Thompson hit out at the regulatory regime within the UK over biomass burning, saying that the company was constrained in what it could achieve.

She said: “We burnt almost one million tonnes last year we could have burnt 1.5 million but we are constrained by regulatory support for what we can do.

“Biomass is the largest source of renewable power in the UK at the moment,” she noted and explained that “there are a number of feedstocks for the Drax plant in North Yorkshire, which provides 7% of the UKs energy supply.

“Of our sources, the vast majority comes from the forestry industry. Secondly, there are agriculture residues, such as starch, olive cake and peanut husks. A third is energy crops and a fourth is organic waste and this is going to become enormous in the future: energy creation is the perfect use for organic waste,” claimed the chief executive.

Responding to questions from her audience, Mrs Thompson said that Drax is trying to find the wood streams which are going to landfill referencing that about 10 million tonnes goes to landfill waste, “garden waste is going to landfill, and we have to find companies that can transport it and we will compress it”.

Farm

But, despite Drax’s intention of using UK-sourced material – it has recently launched its own farm to grow energy crops with the aid of subsidies – the company will still source most of its material from overseas.

The chief executive said: “The UK will become a limited producer but be a significant consumer of global biomass”.

Mrs Thompson continued: “There is an awful lot of marginal land that could grow biomass for energy”.

She added that biomass can produce electricity in two ways, co-firing with coal or in new dedicated biomass plants. It can also be used for heating and transport as biofuels.

Demand

And, she signalled that biomass as a renewable energy source had an advantage compared to other renewable sources because it can better respond to variations in demand.
