How Quest Tankers are helping Turn Food Waste Into Power

 Anaerobic Digestion (AD)

The impact of climate change underscores the growing necessity for an increased utilisation of renewable energy sources, which do not release CO2 or other greenhouse gases into the atmosphere

Did you know that certain waste produced during our daily activities is actually helping to reduce our dependence on fossil fuels? In this post, we look at how the management of food and liquid waste is actively involved in generating clean energy through a method known as anaerobic digestion (AD), highlighting the pivotal role played by Quest Tankers in facilitating this process.

What is anaerobic digestion?

Anaerobic Digestion represents a process where food waste, farm residue, and sewage sludge is placed within a sealed tank (the term “anaerobic” indicating the absence of oxygen), where it decomposes through the action of microorganisms, resulting in the generation of biogas (electricity and heat).

The biogas is predominantly utilised used in engines for Combined Heat and Power (CHP) and contribution to the national power grid.

In 2011, the UK government pledged to increase energy derived from waste through anaerobic digestion in its Anaerobic Digestion Strategy and Action Plan. This commitment is evidenced by the fact that in 2022, the UK used 78,000 metric tons of oil equivalent worth of anaerobic digestion energy to generate heat.

This offers a local, environmentally sound option for waste management which helps us divert waste from landfill, reduce greenhouse gas emissions and produce renewable energy which could be used to power our homes and vehicles.

Aside from the significant benefit of generating clean, renewable energy, anaerobic digestion yields a byproduct known as “digestate,” which also holds positive potential for farmers and gardeners who can also benefit from the fertiliser produced, returning valuable nutrients to the land.

What happens with digestate after anaerobic digestion?

While clean energy is utilised for generating electricity and heat, the byproduct consists of nitrogen and phosphorus, which are valuable components for biofertilizer application in farms throughout the UK.

Biofertilisers, comprising living organisms, enhance growth by augmenting the availability of primary nutrients.

This presents a promising alternative to numerous commercial fertilisers that are perceived as environmentally harmful when applied.

Can Quest Tankers benefit your business?

At Quest Tankers, we specialise in the logistics of digestate from AD plants and distributing it to clients Nationwide.

By responsibly disposing of your food waste, you are actively contributing to renewable energy production. the anaerobic digestion process produces a by-product known as digestate, rich in nitrogen and phosphorus, serving as a valuable biofertiliser.
