Renewable energy as a driver of sustainable growth at Diresco

From energy-intensive production to future-proof profitability

As a manufacturer of high-quality quartz composite, Diresco relies on energy-intensive production processes. Rising energy costs and increasing pressure to reduce CO₂ emissions made it necessary to fundamentally rethink the company’s energy supply. At the same time, Diresco wanted to strengthen its competitive position without compromising quality or operational continuity.

The challenge was clear: finding a sustainable solution that delivers both environmental and financial value — a textbook example of Delivering Profitable Sustainability.

Smart integration of renewable energy and energy management

Together with Encon, Diresco developed an integrated energy strategy. This included the deployment of large-scale solar energy combined with optimised energy management tailored to the production process. By intelligently aligning energy generation and consumption, Diresco was able to maximise the use of its own renewable electricity.

In addition, the entire energy flow within the organisation was analysed, from peak demand management to operational efficiency improvements. The result is a future-ready energy infrastructure that not only supports sustainability objectives but also delivers measurable financial value.

Measurable impact: lower costs, reduced CO₂ emissions and greater competitiveness

The results speak for themselves. Diresco achieved a significant reduction in energy costs by increasing self-consumption of solar energy. At the same time, CO₂ emissions were structurally reduced, contributing to both the company’s sustainability ambitions and its market positioning.

Operationally, the solution provides greater control over energy costs and reduces exposure to volatile energy markets. Financially, this translates into a more stable cost structure and a clear return on investment.

This case demonstrates how sustainability is not merely a compliance requirement, but a strategic lever for growth, efficiency and profitability — Delivering Profitable Sustainability in practice.
