In this project, we investigated the possibilities of maximising the reuse of paper disposables. To this end, we first examined which materials we could extract from them, particularly cellulose. We could then use the residual prpoduct for the production of Brickz. We were successful in this. It also turned out that adding some paper to the Brickz led to an enormous increase in water retention capacity. Partners in the project were Conpax and the Knowledge Centre for Paper and Board.
