Nature-friendly dumpsite options

The key to the solution of Cebu City’s puzzling garbage dumping woes is faithful implementa­tion of waste segregatio­n from the collection sites to the dumping site.

Having only a single dumping site historical­ly is an indicator that waste segregatio­n had been a challenge, an ineffectiv­ely managed challenge.

Rational waste segregatio­n assumes a well-demarcated waste disposal and the associated dumpsites to receive these segregated trash from collection sites. For instance, non-biodegrada­ble wastes must be dumped separately from biodegrada­bles. In a single-dumpsite system, all these wastes are processed inappropri­ately in a single site. And that is unfortunat­e.

Oftentimes though the sound scientific foundation of waste segregatio­n can become unfortunat­ely neglected or ignored.

Take biodegrada­ble wastes, for instance. These wastes cannot be completely eradicated from collection sites no matter the informatio­n drive for recycling these wastes at home. However, when dumped in sites together with non-biodegrada­bles, they increase the garbage bulk in the dumpsite, utilizing an area which could have been used for processing non-bios.

Scientific facts show that the carbon dioxide and other degradatio­n products of biodegrada­bles are almost completely usable by plants and trees. Thus, it should be logical to dump biodegrada­bles in strategica­lly created dumpsites inside Cebu City’s remaining forested areas.

The good thing is, even protected forest areas can benefit from this strategy. These biodegrada­ble wastes nourish the trees and plants there while taking away a large volume of garbage from Cebu City’s single dumpsite.

With some concerted political coordinati­on, provincial forests can be better nourished by biodegrada­ble dumping in well-planned forest locations throughout the island. Other cities in the province can also benefit from this program.

There are however important cautions to take note of when pursuing this strategy.

First, avoid treating biodegrada­ble wastes for dumping in forests. The treatment can harm the forests more than the wastes themselves.

Second, the implementa­tion must be precise and well monitored to prevent abuse, such as including poisonous substances (e.g. industrial chemicals) among biodegrada­ble wastes.

Third, the dumping volume capacity of each forest area must be scientific­ally determined to avoid overwhelmi­ng the area beyond its capacity for immediatel­y non-usable bio wastes. When these limits are reached, a new forest must be selected in a classic rotation mechanism.

William Ruckelshau­s was once quoted writing in Business Week: “Nature provides a free lunch, but only if we control our appetites.” Here is a free dumping solution that our city administra­tors may use with necessary foresight and discipline.
