For decades, the manufacturing industry focused on speed, scale, and low energy costs, often at the expense of the environment.
Today, sustainable practices are becoming the first step for businesses looking to cut emissions, manage water usage, and rethink outdated business practices.
From environmentally-friendly production methods to wider sustainability initiatives, manufacturers are adapting for long-term resilience, especially as demand grows for cleaner supply chains and tech like electric vehicles.
Our latest article covers 17 innovative methods of sustainable manufacturing. From additive 3d manufacturing to waste heat recovery, explore the methods paving the way towards a low-carbon, forward-thinking and resilient future.
It’s worth noting that sustainable manufacturing isn’t always one size fits all, and companies must adapt and find out what works for them.
It begins with small changes and hitting emission hotspots, and ends with broader transitions into a low-carbon, green-thinking business.
Our examples aren’t meant to be followed in order or at once, but could be key jumping pads into more sustainable thinking. A combination of these approaches can kickstart businesses into a stronger position to prepare for the future.

The Importance of Sustainable Manufacturing
For the better part of a century, manufacturing has been one of the most environmentally problematic industries.
It prioritised low costs and high outputs, used virgin materials, and wasteful processes that relied predominantly on fossil fuels. Sustainable manufacturing is way to cut emissions, lower pollution, and end waste with circular loops.
It’s not a rare shift but an integral need, as the world transitions into a low-carbon, circular and progressive economy.
Beyond allowing compliance with new and tightening regulations, it’s no longer a social good to appear sustainable, it’s a social detriment to not act and do so.
It naturally makes business practises more efficient, with supply chains optimised, and hugely reduces risk from resource scarcity by removing dependence on finite sources.
Real World Case Studies
One of the most notable examples of rethinking manufacturing is Patagonia.
Once relying on virgin synthetic and conventional cotton, they swapped 100% of their products to organic cotton in 1996 as an industry first.
This sparked others to follow, such as Nike, Levi’s and H&M.
Patagonia went on to launch closed loop recycling in the early 2000s, largely ahead of their time. It involves taking old products and turning back into new clothing.
Another fantastic real world case is IKEA, who tightened forestry standards in the 2000s recognising deforestation and committed to 100% more sustainable cotton in 2012.
They’ve since made other changes from investing hugely in renewables to only using recycled or renewable materials by 2030.
