Food waste

Plastic Twins

‘Plastic Twins’ explores an alternative recycling process for both single-used plastic and domestic food waste. Together, they can be used to create a family of bioplastic containers, through a very simple process, as easy as cooking a meal. The ingredients are agar agar, glycerol, water and any food waste that is already dried and crushed. In this recipe, designer Hutsama Juntaratana uses eggshells and coffee grounds collected from her own kitchen and the restaurants nearby, as the main ingredients while adding various other wastes to compliment the texture and colour. Plastic water bottles and takeaway containers were used as the mould to pour the mix in, after it was heated and well-mixed on the stove. With their variety in shapes, they can be combined in many ways to create different forms of objects which, in this series, then be used as plant pots.

As home to the plants, Plastic Twins aims to create a domestic circular ecosystem where food waste can be turned into objects hosting the plants that will soon produce food again.
