Big plastic bottles of detergent, such as Persil, have been the household staple for the last few decades. But they are heavy in chemicals such as artificial scents and result in dozens of plastic bottles to waste every year. Alternatives that are natural and effective include:
Laundry Sheets from Simple Living Eco
The refillable Eco Egg and
Soapnuts - organic tree fruits grown in India that contain real natural 'soap' and can be used directly in your washing machine.

Wash clothes less often
Use the 'Eco' setting if your machine has one
Wash cold - 30 degrees C is plenty
Use an eco detergent without harsh chemicals
Ditch fabric softener
Have fuller loads
Air Dry
Consider a microfibre collecting bag
Choose natural materials

Clothing, bedding, and other textiles shed microplastics in fibre form and are major contributors to global plastic pollution. These microfibres, which are stripped and carried off by friction and turbulence in the washing machine, enter our wastewater, eventually ending up in the environment.
To reduce this pollution, choose natural materials and also follow the same guidelines as above:
Wash clothes less often
Use the 'Eco' setting if your machine has one
Wash cold - 30 degrees C is plenty
Use an eco detergent without harsh chemicals
