rosti carbon emission reduction

Rosti Group committed to 50% Carbon Emission by 2030

For the plastic injection moulding industry, where energy intensity and material use play a central role, cutting carbon is both a responsibility and an opportunity.

As a leading plastic injection moulder, we have set ambitious targets to ensure our operations and customer partnerships contribute meaningfully to achieving our sustainability goals.

Rosti Group is committed to a 50% emissions reduction by 2030, fully aligned with the objectives of the Paris Agreement to limit global warming to 1.5°C above pre-industrial levels. Achieving this requires action across every part of our global business – from the energy that powers our facilities, to the materials we use, and the design of the products we manufacture.

Transition to Clean Energy

Energy is the single biggest lever Rosti can pull to reduce emissions independently of customer collaboration. By transforming the way we power our production facilities, we are taking bold steps to eliminate reliance on fossil fuels.

Clean energy falls into two categories: renewable sources such as wind, solar, and hydro, which generate zero emissions, and nuclear energy, which produces minimal emissions. In 2024, we already sourced 56% of our total energy from clean alternatives, with 37% renewable and 19% nuclear.

By 2025, we expect our clean energy usage to exceed 80% – nearly all from renewable sources. Our strategic plan will scale this transition across all facilities, and by 2030 we are committed to operating on 100% clean energy.

At the same time, we are eliminating emissions by improving efficiency. In 2024, we reduced our overall energy requirement by 5% by producing more with less. Our long-term commitment is a 25% improvement in energy efficiency by 2030.

Innovation in Product Design

While clean energy is a powerful lever, more than 70% of Rosti’s emissions are Scope 3, relating to the designs and materials used in our customers’ products. That’s why we are working with customers to bring sustainable solutions from concept to reality through our Innovation and Sustainability Labs.

By helping customers lightweight parts and components, we cut both material use and energy demand in manufacturing, without compromising performance. 

We don’t just provide you with advice – we deliver validated assurance that solutions meet the required quality and industry standards.

 

Product Simplification and Consolidation

Another way we cut emissions is by reducing the number of moulded and assembled components in products. By investing and leveraging our multi-k capabilities, we can combine processes, cut energy use, and lower material consumption.

Case study: For a global hair product brand, we reduced a product from three to two components, saving 65 tonnes of material and achieving a 25% annual CO₂ reduction.

 

Transitioning to Green Material

Material innovation is essential to lowering carbon impact. In 2024, 11% of the material used by Rosti was green – sourced from renewable or recycled resins.

We continue to invest in developing long-term solutions to align with circular economy goals, transitioning to recyclable and low-carbon materials wherever viable. Alongside this, we are advancing raw material recovery and reuse initiatives, further reducing dependence on virgin resources.

Sustainable Packaging and Supply Chain

Packaging and logistics are major contributors to supply chain emissions, so we are rethinking how we support customers in these areas.

We are moving away from single-use cardboard packaging in favour of durable, returnable plastic packaging – a solution that reduces waste while extending product life cycles.

We are also helping optimise transport with foldable packaging solutions that reduce the number of empty journeys, cut fuel consumption, and lower CO₂ emissions across the supply chain.

From our clean energy transition and energy efficiency gains to sustainable product design, material innovation, and supply chain optimisation, we are embedding emissions reduction into every stage of our operations.

By partnering with Rosti, our customers gain more than a contract manufacturer. They gain a partner dedicated to helping them achieve their own sustainability and carbon reduction goals, delivering solutions that are designed for performance, manufactured with responsibility, and aligned with a low-carbon future.
