How did you calculate your carbon assessment?
Our thermal engineering consultant, Ramboll, carried out a Carbon Impact Screening in 2019 to identify the carbon impact of the new Energy Recovery Facility (ERF) once it is operational and to compare it to the carbon impact of sending the waste it will process to landfill.
Though not intended to be a lifetime assessment for the facility, it found that once operational treating waste at the ERF in accordance with our waste forecasts will save the equivalent of 215,000 tonnes of carbon dioxide every year compared to sending it to landfill.
The carbon impact is the sum of the emissions less any savings. Three key principles have been modelled to calculate the carbon impact of the ERF compared to landfill: input (transport and consumables for processing waste), direct (from the processing of waste) and output (offsetting electricity and heat production).
The upgraded ERF will be an integral part of NLWA’s actions to tackle the climate emergency. It will divert rubbish from landfill, which is worst option for the environment and a major contributor of methane emissions. The ERF will also reduce the carbon impact of north London’s non-recyclable rubbish by displacing carbon-intensive processes and virgin fossil fuels. Moreover, the introduction of Carbon Capture and Storage in due course would reduce the carbon footprint of the facility further or completely.
