Sainsbury’s has changed the packing of its own brand liquid laundry detergent from plastic to cardboard, which it says will save 22 tonnes of plastic a year.

The supermarket claims the new packaging will reduce carbon emissions by 50 per cent and the amount of plastic by 80 per cent.

Sainsbury’s said the new cartons are 35 per cent lighter than the original packaging and will take around 13 lorries off the road each year, further reducing carbon emissions.

The change is part of Sainsbury’s wider plans to half the use of plastic packaging in its own brand products and reach net zero targets by 2025.

Earlier this year the supermarket changed the packaging of its beef mince range, claiming the vacuum-packed packaging would save 450 tonnes of plastic each year.

Last year the retailer launched refillable handwash pouches, using 85 per cent less plastic, which save around 28 tonnes of plastic each year and are 35 per cent cheaper than equivalent bottles. Sainsbury’s also launched double-length toilet rolls which save around 84 tonnes of plastic per year.
