Sterlite Power looking for ways to recycle polyethylene (XLPE)

uitdaging

Plastic waste is an extremely valuable resource that power cable manufacturing companies have been accumulating over a period of time. It poses a great opportunity: We want to create a circular economy model where these plastics are used as a chemical feedstock for our products.

About Sterlite Power

Sterlite Power Transmissions Ltd. is India’s leading integrated power transmission developer and solutions provider, focused on addressing complex challenges in the sector by tackling the key constraints of time, space and capital. We believe that electricity access transforms societies and delivers long lasting social impact. Sterlite Power is uniquely positioned to solve the toughest challenges of energy delivery. We need to get rid of a society based on the linear economic model of extract-process-consume-dispose.

In our Global Infrastructure Business, we bid, design, construct, own and operate power transmission assets. Given our expertise in project execution and our experience in delivering cutting-edge technology, we have built a track record of commissioning projects ahead of schedule, addressing the key constraint of time. We help meet the industry’s need for capital by implementing projects on a BOOM (Build Own Operate Maintain) basis and being at the forefront of financial innovation via IndiGrid, India’s first power sector Infrastructure Investment Trust (InvIT). 

From linear to circular

We have collected a large amount of crosslinked polyethylene (XLPE) generated during the manufacturing of insulated cables. Right now, our waste goes into very low value creation such as conversion into other filling purposes. Manufacturers of electric cables are currently using round fillers/dummy elements made of PVC which comes in coil form (as shown in picture 4 and 5 below), typically used as filling or interstices material (picture 6 and 7). Would it be possible to recycle XLPE into a usable material for cable manufacturing? We have already other wastage like PVC, thermo plastic polyethene materials which are easy to recycle/reuse to other form. Where as XLPE is a thermoset polyethylene remains a challenge for us to recycle to another form.

What we are looking for?

We are looking for suitable technology, equipment or solution for recycling or reuse of XLPE for better value creation. Ideally, so that it could be used to produce interstices or other forms of input material that we can incorporate into our production process. Are you open for collaboration. Do you have questions, ideas or suggestions? We are happy to hear from you!

We only recycle a few percent of the plastic worldwide, yet virgin plastic production consumes around 10% of all oil consumption. We want to explore the opportunities of using XLPE plastic waste/scrap as a raw material for cable manufacturing. This way, we will be another step closer to the circular economy.
