Hollander Beater
A Hollander Beater is a machine used to defibrate materials composed of fibres in order to generate a homogenous paper pulp. This pulp can then be shaped in a variety of ways.
By transforming fibres into pulp, the Hollander beater plays an essential role in the textile recycling chain.
Thanks to the European WORTH programme, Mekanika was able to work with fashion designer and material researcher Surzhana Radnaeva to develop an open source Hollander Beater.
Together we were able to develop the first functional beater, which was used to make a first collection of paper clothes from textile waste. We've come full circle!
