Portakabin announces new sustainability initiatives
Leading modular building specialist - The Portakabin Group - has announced new sustainability commitments and initiatives to help customers further reduce their carbon footprint.
Waste streams from the manufacture of modular buildings at Portakabin's international production centre in York, UK, have been increased from 18 to 26. They now include:
- Used vinyl flooring recycled for traffic cones and other plastic products
- Take-back schemes for batteries, fluorescent bulbs, printer cartridges and new vinyl flooring offcuts
- Waste streams for plastics increased from 3 to 5 and mastic tubes are now recycled
- 5 metal waste streams for recycling different grades of steel, aluminium and copper
- Waste from solvents is re-used as furnace fuel.
The Group has invested £100,000 in a high-tech new saw machine which optimises material usage, further reducing waste.
Derek Carter, Chief Executive of the Portakabin Group said: “Our objective of zero waste to landfill at our York factory was successfully achieved in 2013 – and since then we have won a number of awards for environmental excellence. However, we are firmly committed to continually raising the bar and achieving even more improvements to our waste management processes and sustainability performance.
“Our teams across the business are constantly looking at new ways to increase recycling, reduce waste, further improve the recycled content of our products and the re-use of our buildings when they reach end of life. This is all outstanding work which gives our customers even greater confidence in the sustainability of our approach and in the reduced carbon footprint of all of our buildings.”
The company's latest initiatives follow a host of existing commitments, including Portakabin sourcing its steel supplies locally. 79 percent of the steel used in its modular manufacturing process continues to be supplied from within the UK, which is more sustainable, strongly supports British manufacturing, procures steel of the highest quality, and minimises the carbon footprint of Portakabin buildings.
Other new waste minimisation initiatives:
- The Group’s 50 UK Hire and Visitor Centres now separate out paper and cardboard for recycling, and plasterboard on the larger sites
- Investment in specially-designed containers to hold and protect components for the modular manufacturing process. These ‘stillages’ are then sent back to suppliers for re-filling, removing the need for packaging
- The introduction of a new reporting structure to achieve further reductions in energy consumption and waste, and demonstrating the importance Portakabin places on leadership in this area
- Increased use of internal education programmes to continually raise awareness of waste management best practice among staff at every level
- An active Corporate Social Responsibility (CSR) programme which instigates and promotes community recycling initiatives across the Group – such as collections for local clothes banks and for the distribution of spectacles to developing countries; the donation of carpet tiles and furniture to local schools and libraries following an office refurbishment, and timber offcuts to help Portakabin volunteers transform an area of wasteland into an allotment for local children
- The extension of a programme to segregate and recycle six streams of office waste. This is now being rolled out across the whole of the York headquarters site, following successful trials
- Portakabin now has compactors for general waste and bailers at its York manufacturing centre to put cardboard, soft plastics, plastic bottles and plastic strapping into bails. This reduces transportation and carbon emissions by achieving higher tonnage with each truck movement.

Ultium Cells LLC/Li-Cycle: Sustainable Battery Manufacturing
Ultium Cells LLC - a joint venture between General Motors and LG Energy Solutions - has announced its latest collaboration with Li-Cycle. Joining forces the two have set ambitions to expand recycling in North America, recycling up to 100% of the scrap materials in battery cell manufacturing
What is Ultium Cells LLC?
Announcing their partnership in December 2019, General Motors (GM) and LG Energy Solutions established Ultium Cells LLC with a mission to “ensure excellence of Battery Cell Manufacturing through implementation of best practices from each company to contribute [to the] expansion of a Zero Emission propulsion on a global scale.”
Who is Li-Cycle?
Founded in 2016, Li-Cycle leverages innovative solutions to address emerging and urgent challenges around the world.
As the use of Lithium-ion rechargeable batteries in automotive, industrial energy storage, and consumer electronic applications rises, Li-Cycle believes that “the world needs improved technology and supply chain innovations to better recycle these batteries, while also meeting the rapidly growing demand for critical and scarce battery-grade materials.”
Why are Ultium Cells LLC and Li-Cycle join forces?
By joining forces to expand the recycling of scrap materials in battery cell manufacturing in North America, the new recycling process will allow Ultium Cells LLC to recycle cobalt, nickel, lithium, graphite, copper, manganese and aluminum.
“95% of these materials can be used in the production of new batteries or for adjacent industries,” says GM, who explains that the new hydrometallurgical process emits 30% less greenhouse gases (GHGs) than traditional processes, minimising the environmental impact. Use of this process will begin later in the year (2021).
"Our combined efforts with Ultium Cells will be instrumental in redirecting battery manufacturing scrap from landfills and returning a substantial amount of valuable battery-grade materials back into the battery supply chain. This partnership is a critical step forward in advancing our proven lithium-ion resource recovery technology as a more sustainable alternative to mining, " said Ajay Kochhar, President, CEO and co-founder of Li-Cycle.
"GM's zero-waste initiative aims to divert more than 90% of its manufacturing waste from landfills and incineration globally by 2025. Now, we're going to work closely with Ultium Cells and Li-Cycle to help the industry get even better use out of the materials,” added Ken Morris, Vice President of Electric and Autonomous Vehicles, GM.
Since 2013, GM has recycled or reused 100% of the battery packs it has received from customers, with most current GM EVs repaired with refurbished packs.
"We strive to make more with less waste and energy expended. This is a crucial step in improving the sustainability of our components and manufacturing processes,” concluded Thomas Gallagher, Chief Operating Officer, Ultium Cells LLC.
