A city has set a goal of zero waste. The city wants to focus on recovering resources that are traditionally considered garbage. Which of the following would be consistent with the city’s zero-waste goal ?
A. Providing free kitchen compost bins
B. Burying hazardous waste
C. Increasing the size of garbage cans
D. Downsizing recycling facilities

Among the options given A. Providing free kitchen compost bins is the correct one because compositing is the decomposition as well as a recycling process in which the biodegradable wastes are covered in a heap of debris where these wastes decompose off with the action of the biological agents present in the soil such as bacteria. The waste is transformed into humus or organic matter that is rich in organic carbon content which can be used as natural manure.

Compost bins will play the same role as a traditional compositing method will do. Therefore, this technique will ensure the disposal and recycling of waste at the individual level and hence will support the notion of zero waste in the city.
