Our city generates an astonishing 60,000 tons of solid waste a year, in which 50% is food waste. I, being the mayor should and will speak for the benefits and health of our people. We should use compost as our main waste management system as it is sustainable, efficient, and is the most fitting system for our city.
First, compost is very beneficial to our economy. The organic materials cost practically nothing, because you’ve already paid for the value in the food. We can export the compost material to farmers, and have more local businesses based on composting and growing crops. Moreover, markets usually favor organically grown crops, as a result, bringing higher prices.
Second, compost is an effective way to increase healthy plant production, therefore benefiting agriculture. Compost reduces the use of chemical fertilizers, and improves the physical, chemical, and biological properties of soils, therefore redeeming soil quality and root production. It contains all the major nutrients essential for plants, namely calcium, zinc, and manganese. Furthermore, composting keeps out and reduces unwanted plant diseases and pathogens, which may result in crop losses.
Third, compost supports the environment in many ways. It avoids methane production and leachate formation in landfills by diverting organics for compost. Similarly, it prevents pollutants in storm water runoff from reaching water resources, and protects groundwater quality. Besides, compost minimizes odors from agricultural areas such as farms and factories.
In addition, compost can be done by practically everyone. You’ll never run out of things to compost, because there are 163 organic materials that are compostable. The materials have a huge variety, from everyday leftovers such as eggshells, potato peelings and corncobs, or by-products of wine and beer. You just need 4 things: time, space, materials, and desire.
In conclusion, compost is an extremely easy waste management system to operate that can benefit the economy, support the environment, and most importantly, everyone can be involved. Therefore, we should use compost as our main solid waste management system.
