Plastics manufacturing is among the highest industrial energy user in the UK, making electricity both a cost burden and a sustainability challenge. Energy consumption is largely driven by extrusion lines, injection and blow moulding machines, cooling systems and temperature-controlled storage, and other equipment such as dryers, grinders, conveyors and compressors.
In this article, we explore the role of solar energy in supporting plastics manufacturers in meeting regulatory demands, improving cost efficiency and strengthening their sustainability credentials.
Sustainability Pressures for Plastics Manufacturers
Over the years, there have been increasing regulatory pressures on the manufacturing sector to become more sustainable. One of the main demands is the UK Government’s Net Zero strategy, which aims to decarbonise the UK economy by 2050 through emissions reductions and wider adoption of low-carbon technologies. This strategy has significantly increased expectations for renewable energy use and verified emissions reporting across industries, including plastics manufacturing.
Other regulatory obligations that place pressure on plastics manufacturers include:
- UK Plastic Packaging Tax (PPT): Requires companies manufacturing or importing plastic packaging into the UK to ensure it contains at least 30% recycled plastic; otherwise, the packaging is liable for the Plastic Packaging Tax.
- Energy Savings Opportunity Scheme (ESOS): The Government introduced this for businesses to identify energy-saving opportunities. Qualifying energy-intensive sites must complete detailed energy audits at least every four years and identify cost-effective energy saving measures.
Supply Chain & Market Expectations
Major retailers and Fast Moving Consumer Goods (FMCG) brands now prioritise suppliers and manufacturers with credible sustainability strategies and practices. So much so, those relying solely on grid electricity risk losing tenders to more sustainable competitors.
With more data requests for carbon footprints, energy sources and progress towards Net Zero commitments, complete transparency on environmental impact is paramount.
How Solar Can Decarbonise Plastics Production Processes
Supports Heavy-Load Equipment
Three-phase inverters are designed to manage heavier electrical loads that run on a three-phase power supply. They distribute power across all three phases and provide a stable and efficient energy flow – ideal for equipment that operates continuously, such as high tonnage moulding machines, industrial cooling systems, and high-pressure compressors.
Improves Grid Stability
On-site solar energy generation helps stabilise the site’s electrical profile by reducing dependency on the external grid. Plastics manufacturing facilities may sometimes experience voltage dips or transient supply issues due to high, fluctuating loads.
This can lead to interruptions, shutdowns, increased waste and potential delays. With solar power, an extra layer or power resilience gives manufacturers an operational advantage for continuous or multi-shift production lines.
Solar Energy’s Role in Environmental, Social & Governance (ESG)
Aligns with UK Standards
Renewable energy generation contributes directly towards reduction in Scope 2 emissions – an essential component of sustainability and Net Zero reporting. It also plays a significant role in ESOS compliance and ISO 14001 environmental management systems (EMS) – a framework that helps organisations continually improve their environmental performance.
Competitive Advantage in Procurement
Manufacturers using solar panels can demonstrate lower carbon footprints, reduced environmental impact per production cycle and strong sustainability credentials. These can all be decisive factors in both securing and retaining supply chain contracts and major customer tenders.
Financial Benefits for Plastics Manufacturers
Reduced Long-Term Operating Costs
Once installed, solar power offsets energy usage, contributing to long-term savings. Reduced exposure to rising carbon-linked grid costs leads to more predictable annual budgeting. With these operational savings, manufacturing facilities can free up capital for new machinery, R&D investments, process improvements and other investments.
Our client, Oadby Plastics, consumes 75% of their generated power on site, saving on rising energy costs, with an estimated payback period of less than four years. This is a prime example of how solar energy solutions deliver financial benefits, as well as measurable carbon reductions across high-consumption manufacturing environments.
At Noble Green Energy, we specialise in installing commercial solar solutions tailored to different industries, including plastics manufacturers. Talk to us today to help you increase sustainability while reducing energy costs and consumption.
