MKM Has Sustainability In The Bag
MKM Building Supplies has become the first builders’ merchant to roll out bulk bags made from 100% recycled material. It has been developed in partnership with Centurion Industrial Packaging.
The new MKM bulk bags are made entirely from recycled polypropylene, including the stitching and labelling, offering a market-first solution that minimises landfill, helps customers cut waste and smashes the current environmental regulation requirements.
“This isn’t about ticking boxes, it’s about leading the industry forward,” says Ric Bauer, MKM’s head of building materials. “We’ve gone from 30% recycled content to 100% across all 135 branches. It’s better for customers, better for compliance, and better for the planet.”
100% recyclable
Bauer continues: "Most industry-standard bulk bags contain just 30% recycled content, which is the legal minimum. MKM’s new bags use 100% recycled polypropylene, which means diverting significant plastic waste from landfill and reducing the demand for virgin materials.”
Strength
Independently strength-tested in the UK, the bags meet rigorous safety standards. While designed for single use in line with industry safety regulations, they remain robust enough for a variety of secondary uses by landscapers and homeowners.
“This is packaging with purpose,” says David Lomas, the sustainability director at Centurion Industrial Packaging. “MKM came to us to challenge what was possible for their bulk bags and we’re proud to have created a solution that combines performance and sustainability.”
Wins for customers
The switch to fully recycled bags significantly reduces MKM’s environmental footprint, lowering the carbon impact of both materials and waste disposal. In turn, this helps customers with:
-
Compliance with new waste separation rules. As of 31 March 2025, all UK businesses with over 10 employees must separate recyclable materials at source.
-
Site waste management plans. Using recyclable bags supports construction businesses in meeting regulatory expectations and sustainability targets.
A rollout at scale
MKM is already distributing 65,000 bags per month across its 135 branches, with projections that 800,000 fully recyclable bags will be used each year as the business scales. An initial bulk order of 250,000 100% recycled bags has been secured from Centurion to ensure continuous supply and protect against global shipping disruptions.
