Waste recycling technologies for nanomaterials manufacturing This book discusses the recent advances in the wastes recycling technologies to provide low cost and alternative ways for nanomaterials production. It shows how carbon nanomaterials can be synthesized from different waste sources such as banana fibers argan (Argania spinosa) seed shells corn grains camellia oleifera shell sugar cane bagasse oil palm (empty fruit bunches and leaves) and palm kernel shells. Several nanostructured metal oxides (MnO2 Co3O4 ….) can be synthesized via recycling of spent batteries. The recovered nanomaterials can be applied in many applications including: Energy (supercapacitors solar cells etc.) water treatments (heavy metal ions and dyes removal) and other applications. Spent battery and agriculture waste are rich precursors for metals and carbon respectively. The book also explores the various recycling techniques agriculture waste recycling batteries recycling and different applications of the recycled materials. .
