Answer:
The value that can help in changing the urban waste into resources are:
1. Creating awareness: Societies should be made aware for using the urban waste in the productive use for example - kitchen and garden waste can be converted into compost. Sewage can be used to produce biogas.
2. To evolve the new techniques: Innovative production techniques should be used such as waste exchanges process in which the waste product of one process becomes the raw material for a next process. Waste exchanges process will help to use waste which is difficult to eliminate for example in the manufacturing of soap glycerin will be extracted from the waste.
3. Caring attitude towards urban waste: The urban waste should be treated with care as Scraps can be re-used at the beginning of the manufacturing process so that they do not become a waste product for example, paper mills use the damaged rolls to the beginning of the production line, the metal and plastic items, can be re-incorporated into new products.
