Trelleborg Seals & Profiles: A commitment to clean energy and circular practices

At Trelleborg Seals & Profiles, sustainability and circularity are more than just guiding principles – they are actionable commitments that drive measurable change across our global operations. As a world leader in engineered polymer solutions, we are proud to contribute to the transition to a low-carbon society by embedding resource efficiency and circularity into our processes. Among our milestones is the notable progress made at our Milford production facility in New Hampshire, United States. The facility is an example of how sustainability can be integrated into every aspect of operations.

Commitment to clean energy

In line with Trelleborg’s goal to reduce Scope 1 and 2 carbon emissions by 50% by 2030, Milford facility uses 100%renewable electricity., ensuring that our operations remain efficient while staying true to our climate targets. By investing in renewable energy, Milford is setting the standard for sustainable manufacturing and demonstrating how operational decisions can support global environmental goals such as the United Nations’ Sustainable Development Goals (SDGs) 12 (responsible consumption and production) and 13 (climate action).

Doing more with less

Milford’s commitment to sustainability is also evident in its efforts to improve process efficiency. From rubber molding and extrusion to plastic molding, the facility has implemented innovations that reduce energy consumption, minimize waste, and increase productivity.

Rubber molding

The rubber molding process at Milford has undergone a significant transformation. By upgrading to larger, more efficient molding machines and specially designed multicavity molds, the facility now produces two to four times more parts per cycle. While the energy consumption per hour has increased slightly, the energy consumption per part has decreased significantly. This approach optimizes the use of resources and minimizes the carbon footprint of each product.

Hot sprue system

In addition, the new mold design incorporates a hot sprue system to minimize scrap. Any scrap generated is ground on-site and sold to recycling companies, ensuring 100% diversion from landfills. This commitment to circularity addresses waste and supports the broader transition to a circular economy, where materials are reused and repurposed for as long as possible.

Rubber extrusion

One of the most exciting sustainability initiatives at Milford is underway in its rubber extrusion process. Starting in the winter of 2025, the facility will replace two chillers with forced convection heat exchangers. During colder months, the excess heat will be used to warm the plant, and in warmer months, it will be vented outside. This innovation reduces energy demand while providing efficient temperature management, underscoring Milford’s commitment to resource efficiency.

Closing the loop

Circularity remains at the heart of Milford’s operations. By redesigning processes to reduce waste and repurpose materials, the facility embodies Trelleborg’s commitment to sustainable production. From minimizing runner waste in injection molding to partnering with recycling companies to repurpose excess materials, Milford demonstrates how industrial operations can be aligned with circular economy principles.

These achievements underscore a broader vision: to lead our industry in sustainable innovation. Milford’s efforts help contribute to our corporate goals while setting an example for sustainable manufacturing in the polymer industry. By aligning with science-based targets and focusing on smaller measurable outcomes, Trelleborg is making significant progress toward reducing its global environmental footprint.

Looking ahead

The Milford facility continues to integrate sustainable practices into every aspect of its operations as part of its ongoing commitment to sustainability. From investments in clean energy to continuous process improvements, Milford exemplifies how innovation and environmental responsibility can coexist. As Trelleborg Seals & Profiles continues to lead the way in engineered polymer solutions, we remain committed to driving resource efficiency, promoting circularity, and achieving our climate goals across all facilities. By prioritizing sustainability at every level, Milford shows that operational excellence and environmental stewardship can create a pathway to a more sustainable future.
