Green Manufacturing: How Solar Power is Driving the Future of Industrial Cores

By Harry Coates | Managing Director, Just Paper Tubes

At Just Paper Tubes, we have been the backbone of British and European supply chains for 38 years. Producing over 50 million cores annually, our products support a vast array of sectors—from flooring to flexible packaging.

But manufacturing on this scale demands significant energy. Whether we are winding heavy-duty carpet tubes or precision-engineered high performance film cores, the process requires heat, power, and consistency.

Recently, JPT took a major step to future-proof our production. By installing a cutting-edge Commercial & Industrial Energy Storage System paired with high-capacity solar, we are ensuring that your cores aren't just high quality—they are low carbon.

The Energy Behind Your Cores

Manufacturing cardboard tubes is an energy-intensive process. To ensure the structural integrity of products like industrial cores, we utilize advanced enviromental control systems along with drying ovens. This ensures that the moisture content is perfectly regulated, preventing warping or crushing under load.

However, relying solely on the grid for this process is no longer sustainable—economically or environmentally. We realised that to continue supplying the best tape cores and label cores at competitive prices, we needed to take control of our energy supply.

"More Solar really helps us unlock savings because we were spending vast amounts on electricity for drying ovens. Being able to use our own energy is great for sustainability and price stability."

Powered by Sungrow: A Technical Leap

We partnered with Innasol and Sungrow to completely overhaul our power infrastructure at our Selby facility.

1. Liquid-Cooled Storage: We installed the Sungrow PowerStack, a liquid-cooled battery energy storage system. This allows us to store solar energy generated during the day and use it during peak times or overnight production runs.

   
   

2. Efficiency at Scale: By replacing old G59 systems with modern inverters, we ensure that the energy used to wind your carpet tubes is as efficient as possible.

"From an installer's point of view, the build quality is top notch. One of the great features of the PowerStack is the liquid cooling facility. It allows the batteries to operate at a higher efficiency level, keeping the temperature moderate through operational cycles. That, in turn, gives the battery a longer life."
