Radiation data analytics and project feasibility studies are absolutely critical for the successful planning of energy-efficient solar projects. Accurate radiation data allows for precise predictions of energy generation, system sizing and financial returns. By analysing radiation patterns, engineers can optimise system design, including orientation and tilt angles, to maximise energy capture. Feasibility studies help identify potential risks, such as shading or grid constraints, enabling proactive solutions. These studies also assess financial viability, considering ROI, payback periods, and incentives, ensuring projects are economically sound enabling data-driven decision-making throughout the project lifecycle.

Looking ahead, what are the key trends and innovations in energy efficiency that Servotech Power Systems plans to focus on in the near future?
Energy efficiency is a dynamic realm with constant emergence of trends and innovations.

Leading industry bodies, including the Global Cement and Concrete Association (GCCA), European Composites Industry Association, International Solid Waste Association – Africa, Mission Possible Partnership and the Global Waste-to-Energy Research and Technology Council, have issued a joint statement highlighting the cement industry’s potential role in addressing the growing global challenge of non-recyclable and non-reusable waste. The organisations have called for stronger policy support to unlock the full potential of cement industry co-processing as a safe, effective and sustainable waste management solution.

Co-processing enables both energy recovery and material recycling by using suitable waste to replace fossil fuels in cement kilns, while simultaneously recycling residual ash into the cement itself. This integrated approach delivers a zero-waste solution, reduces landfill dependence and complements conventional recycling by addressing waste streams that cannot be recycled or are contaminated.

Already recognised across regions including Europe, India, Latin America and North America, co-processing operates under strict regulatory and technical frameworks to ensure high standards of safety, emissions control and transparency.

Commenting on the initiative, Thomas Guillot, Chief Executive of the GCCA, said co-processing offers a circular, community-friendly waste solution but requires effective regulatory frameworks and supportive public policy to scale further. He noted that while some cement kilns already substitute over 90 per cent of their fuel with waste, many regions still lack established practices.

The joint statement urges governments and institutions to formally recognise co-processing within waste policy frameworks, support waste collection and pre-treatment, streamline permitting, count recycled material towards national recycling targets, and provide fiscal incentives that reflect environmental benefits. It also calls for stronger public–private partnerships and international knowledge sharing.

With global waste generation estimated at over 11 billion tonnes annually and uncontrolled municipal waste projected to rise sharply by 2050, the signatories believe co-processing represents a practical and scalable response. With appropriate policy backing, it can help divert waste from landfills, reduce fossil fuel use in cement manufacturing and transform waste into a valuable societal resource.

Leading industry organisations have called for stronger policy support to accelerate the adoption of cement industry co-processing as a sustainable solution for managing non-recyclable and non-reusable waste. In a joint statement, bodies including the Global Cement and Concrete Association, European Composites Industry Association, International Solid Waste Association – Africa, Mission Possible Partnership and the Global Waste-to-Energy Research and Technology Council highlighted the role co-processing can play in addressing the growing global waste challenge.

Co-processing enables the use of waste as an alternative to fossil fuels in cement kilns, while residual ash is incorporated into cementitious materials, resulting in a zero-waste process. The approach supports both energy recovery and material recycling, complements conventional recycling systems and reduces reliance on landfill infrastructure. It is primarily applied to waste streams that are contaminated or unsuitable for recycling.

The organisations noted that co-processing is already recognised in regions such as Europe, India, Latin America and North America, operating under regulated frameworks to ensure safety, emissions control and transparency. However, adoption remains uneven globally, with some plants achieving over 90 per cent fuel substitution while others lack enabling policies.

The statement urged governments and institutions to formally recognise co-processing in waste management frameworks, streamline environmental permitting, incentivise waste collection and pre-treatment, account for recycled material content in national targets, and support public-private partnerships. The call comes amid rising global waste volumes, which are estimated at over 11 billion tonnes annually, with unmanaged waste contributing to greenhouse gas emissions, pollution and health risks.
