Embodiments disclosed herein provide a bucket assembly and method of use thereof. The bucket assembly is a relatively lightweight and removable apparatus that can fracture cut, paddle, and heat contents contained therein. The bucket assembly can include a housing that has a curved metal plate and blade array attached thereto. A cut and paddle assembly can rotate within the housing and interface with the blade array to fracture cut contents contained therein. The cut and paddle assembly is also operative to mix the contents to ensure full dispersal within the housing. A flexible heater array is attached to and operative to heat the curved metal plate. The combination of the fracture cutting, paddling, and heating can convert organic matter to a ground and selectively desiccated product.

A shredder for shredding material, the shredder comprising a housing supporting two rotating shafts arranged parallel to each other, each shaft having a plurality of overlapping and offset transverse shredding blades along the shafts able to rotate on the shafts in a complementary fashion to shred the material thereinbetween, the shredding blade on each shaft nearest to the housing being an outermost shredding blade and having a gap between of the outermost shredding blade and the housing, wherein the gap at least partly comprises a V-shape.
