The Muwi innovation lawn mower takes the seemingly useless byproduct of grass cuttings and turns it into something fun. But first, Muwi calculates the size of the lawn and automatically cuts the grass. As the grass cuttings accumulate inside the machine, Muwi constructs and compresses them into cylindrical blocks. The blocks can become balls for children to play with or be combined to make a chair or anything else you can think of. After the blocks are used, they can be left to return to nature.
