The principle of refills is that containers for products are refilled and returned home instead of buying new ones, such as glass bottles for doorstep milk deliveries. Though refill services used to be commonplace, changes in the market and availability of raw material saw their decline. However, there remain many benefits to the system; for example the costs-savings of bulk-buying the products to go inside the refillable containers can be passed on to consumers. Refill systems also produce much less waste overall.
Lots of products are available as refills, including cleaning products, washing powder, cosmetic products like shampoo and dry foods such as breakfast cereals, flour, nuts and dried fruit. Some larger companies have begun to offer refills in their stores. Local shops often have more opportunities for less packaging and you can sometimes take your own containers along as well.
