REA finds food waste collection ‘cost effective’
A new report by the Renewable Energy Association (REA) has revealed that mandatory separate food waste collections in England would likely yield savings for both councils and businesses.
The UK has agreed to increase the total recycling rate to 50 percent by 2020. Despite this, only 10 percent of household food waste in the UK is currently recycled — and only 45 percent of local authorities collect food waste. Many businesses don’t recycle at all.
The model used in the REA’s report suggests that, with a separate collection system, a company that produces 500kg of food waste per week could save more than £900 annually. Recent findings by WRAP have stated that roughly 1.9 million tonnes of food is wasted in the UK grocery supply chain every year.
For local authorities that operate weekly ‘residual’ waste collection, it was proven that a switch to fortnightly residual service and a weekly food waste collection would save between £10 and £20 per household each year.
Additional benefits of separate collection include: reducing the weight of general waste, thereby reducing landfill gate fees, and increasing and improving dry recycling.
Separating food from residual waste collections would also help to grow the green gas sector, as food waste can be used to ‘fuel’ an anaerobic digestion plant.
Nina Skorupska, CEO at the REA said: “Separate food waste collections is a cost-effective policy that can help us hit our recycling target, reduce harmful greenhouse gas emissions and improve our energy security in one fell swoop.
“Many regions, including Scotland, Wales and many regions in Europe, have realised the benefits of not letting food waste go to waste. There’s a range of companies now in the UK that are producing their own renewable heat and power from it or even fuelling vehicles with it.”

Trafigura and Yara International explore clean ammonia usage
Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050.
How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.
Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:
- The supply of clean ammonia by Yara to Trafigura Group companies
- Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
- Development of new clean ammonia assets including marine fuel infrastructure and market opportunities
Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.
There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.
Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.
Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.
Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.
It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
