DHL’s new £3.8million waste plant is reported to not only disposes of Category 1 waste safely onsite, it converts it and other organic waste into energy to heat Gatwick’s waste management site and power the site's water recovery system. The plant is expected to save £1,000 in energy and waste management costs for every day it operates.
Category 1 forms the majority of waste from non-EU flights and is defined as food waste or anything mixed with it, such as packaging, cups and meal trays from international transport vehicles. Through the plant, waste is turned into a dry-powdered organic material, used as fuel to heat the site and dry the waste for the next day.
Gatwick is reported to currently treats 2,200 tonnes of Category 1 waste each year, around 20% of the total generated at the airport (10,500 tonnes). The new energy plant is anticipated to process around 10 tonnes per day, whereas all Category 1 waste was previously processed offsite.
With the objective of boosting the airport’s recycling rate from 49% today to around 85% by 2020 - higher than any UK airport - the plant includes a waste sorting centre to maximise recycling onsite. Concentrating all activities in one location enables the team to transport waste four times more efficiently than before, reducing local traffic and carbon emissions.
The plant is also said to have been designed with the future in mind and has the capacity to produce additional energy that could one day be used to power other areas of the airport.
“On our journey to become the UK’s most sustainable airport, our new world-beating waste plant turns a difficult waste problem into a sustainable energy source. We’re confident it sets the benchmark for others to follow in waste management,” said Stewart Wingate, Gatwick CEO.
“Our ambitious plans to develop in the most environmentally responsible way possible are driven by a set of rigorous targets. Despite passenger numbers doubling, our environmental footprint is better today than it was in the early 1990s.”
Martin Willmor, senior vice president, specialist services, UK, DHL Supply Chain, added: “Disposing of Category 1 waste can be very costly and time-consuming, but our new waste management and recycling system is a huge step forward.
“Gatwick is leading the way in converting waste onsite into an energy source and we’re already investigating a number of further initiatives to support sustainable energy production and the future expansion of the airport.”
According to DHL Supply Chain, it already manages inbound deliveries at Gatwick Airport through its logistics and consolidation facility on behalf of the airport’s 150 partners and retailers.
