The Resource Cycle Resources A resource cycle is the process involving the and transformation of a raw material into a usable raw material or consumable product and its disposal. It starts Final disposal Mining, cultivating with extraction of resources and raw materials Resources through mining, cultivating, and/or harvesting. withdrawal The extracted materials are then processed, Waste, residuals transported, and manufactured into new products and pollution GEOSPHERE to be delivered to or purchased by consumers. Purchase and use HYDROSPHERE by consumer ATMOSPHERE During these stages, waste can be generated. These BIOSPHERE wastes affect Earth's subsystems-geosphere, hydrosphere, atmosphere, and biosphere-which provide the resources and raw materials. Reducing Transport the demand of resources, minimizing waste, of products and recycling and reusing of materials may help balance the production of resources and disposal Manufacturing of produacts of waste. Fig. 6-9. The resource cycle Waste Management Waste management in homes, schools, communities, and industries can be done using prevention the waste management hierarchy of options. The most minimization effective way to reduce waste is to reduce the waste reuse at the source. It involves buying durable products more favorable recycling that can be used for a long time and refraining from buying disposable products that lead to more waste. The second option is to reuse and recycle solid waste to serve another purpose. This includes reusing plastic bags, empty bottles, and other disposable materials, Organic waste such as leftover food and vegetable peelings can also be converted into compost for planting through different techniques of biocomposting, The third option is the treatment of waste to minimize its Fig, 6:10. Waste management hierarchy ducts on the environment, Only until all these options are exhausted and done should solid waste be disposed to properly designed and operated waste disposal facilities Chapter | We've Only Just
