Roma Grus AB, a family-owned business based on the island of Gotland in Sweden, has long been a key supplier of construction materials to the local industry. In 2021, the company took a bold step toward sustainability by making the decision to acquire a cutting-edge recycling plant from CDE. This strategic move marked a turning point in the island’s approach to resource management, enabling Roma Grus to transform construction, demolition, and excavation waste into high-quality, CE-marked materials for concrete and infrastructure projects. The partnership between Roma Grus and CDE is a powerful example of how circular economy principles can be applied to protect an ecosystem while supporting economic growth.
Roma Grus AB - Preserving Gotland - 140tph Waste Recycling Plant in Sweden
The Geographical Challenge
Gotland’s unique geography presents significant challenges. As an island, it has no revery little access to raw material reserves, making it heavily dependent on imports from mainland Sweden. This reliance not only increases costs but also contributes to environmental degradation through transport emissions and resource extraction.
The island’s biodiversity and groundwater supply are under pressure, and upcoming regulations prohibit raw material extraction for market supply. At the same time, Gotland faces a growing housing shortage, particularly in Visby, which demands rapid infrastructure development.
Roma Grus recognised that continuing to rely on virgin materials was neither sustainable nor viable and sought a solution that would allow them to meet local demand while protecting the island’s natural resources.
The CDE Solution
CDE engineered for Roma Grus a 140tph wet processing plant capable of recycling construction & demolition waste, and excavated soils into clean, certified construction materials.
The plant features the R4500 primary scalping screen, the AggMax™ logwasher, a CFCU fine sand density classification system, an EvoWash™ sand wash plant, aggregates and sand sizing screens, and a water management system which recycles up to 90% of the water into the process. This setup allows Roma Grus to produce a range of recycled aggregates and sands suitable for concrete production, infrastructure projects, and landscaping.
The materials are processed, separated, and quality-checked before being stored and delivered to customers across the island.
The Results
The impact of the CDE solution has been profound. In its first year, the plant processed 60,000 tonnes of material, increasing to 90,000 tonnes the following year, with projections exceeding 120,000 tonnes in 2025. The plant has become the heart of Roma Grus’s operations, enabling them to offer a full-cycle waste management service where customers can drop off waste and leave with clean, usable materials.
The company has gained national recognition, with industry peers and government officials visiting the site and has initiated a shift in public and industry attitudes toward recycled materials, demonstrating that they can match or exceed the quality of virgin products. The recycled materials are now used in major housing developments led by GotlandsHem and Peab AB, helping to address the island’s housing crisis while embedding sustainability into every project.
Roma Grus is also aligning its operations with Sweden’s net-zero goals by planning the installation of 6,000 solar panels and exploring the use of biogas from local farms to fuel its transport fleet. The company’s journey reflects a broader shift toward circularity, and its success serves as a blueprint for other island and mainland communities
