The main use of garden shredders and chippers is to reduce garden waste – whether it is for composting or just for easier disposal. Having homemade compost (courtesy of your garden shredder) to hand is invaluable to all gardeners. Types of waste that can go into garden shredders and chippers includes hedge off-cuttings, foliage from plants, leaves and twigs. You could even put kitchen waste like vegetables and fruit peelings into a garden shredder.
