Zero-Waste Laundry Detergents With Innovative Twists — Pods, Tablets, and More – Green Matters

While most of the other laundry detergents on this list are somewhat recent innovations, soap nuts have been around since before you were born. Soap Nuts, commonly sold by the brand Eco Nuts, are actually berry shells that grow on the Soap Berry tree in the Himalayas. The soap nuts naturally contain a cleaning agent called saponin — meaning they happen to do a really good job of cleaning clothes.

To use Eco Nuts, you just put four or five of the soap nuts into the provided cloth bag, and throw the bag into the washing machine with each cycle, where they will naturally sud up. Each berry can be reused up to 10 times.

Soap Nuts are not ranked by the EWG, but you can rest assured that they are safe and gentle to use, as they are grown without pesticides and contain just one whole, plant-based ingredient.

Eco Nuts also sells liquid laundry detergent made from soap berry extract, as well as a few other household cleaning products. You can shop Eco Nuts on the company’s website.
