MODULE 5. SOLID WASTE

solid waste

By the year 2050, it is projected that the amount of solid waste generated on Earth might reach up to 3.40 billion tonnes.Highly urbanized cities continue to grow their trash as residents end up buying packaged items. Developing countries are more severely impacted by unmanaged solid waste compared with developed countries.Uncontrolled waste generation prompts the public to burn their garbage instead to control the volume and public health dangers associated with solid waste. Additionally, poorly managed waste will serve as a gateway for disease vectors to proliferate and contribute to climate change.
In the Philippines, the projected annual waste was at 18.05 Million Tons.52% of solid waste generated in the country is biodegradable, and most solid waste produced comes from residential sources. Only 22% of Local Government Units have access to sanitary landfills, and there were still 353 illegal dumpsites that remain operational

prevention, reuse, recycling, and treatment

Managing waste have evidently become significant for achieving a sustainable city, but it remains a challenge for developing countries and cities. It is because effective waste prevention, reuse, and recycling treatment is expensive and requires efficient, sustainable and socially supported waste treatment systems.
Despite limited municipal budgets for implementing solid waste management programs, different countries were able to develop strategies to reform waste prevention, reuse and recycling practices with the help of World Bank in providing technical assistance and financing waste management projects.
Shown in the right figure are the waste treatment techniques and the potential products that can be produced from different solid waste treatment

circular economy

Circular economy is a closed-loop system of producing and consuming existing materials and products. It involves sharing, leasing, reusing, repairing, and recycling materials to reduce waste which maximizes the value of materials and resources by keeping them in use as long as possible.
Keeping products and materials in a circular economy can create a system that puts back the resources used in nature more than the number of resources that need to be extracted just to yield usable materials. This approach can allow the planet to regenerate itself since waste generation is reduced, thereby giving us and the future generations the things that we need for survival.

reflection:

This module tackled the importance of reuse, recycling, and treatment of waste as well as maintaining a circular economy in managing solid wastes. After thoroughly studying the subtopics, I learned so many things on how to correctly manage solid waste in a household. With this, I realized that proper solid waste management is important for the protection of public health and clean environment. It is because the amount of waste generated affects the environment in following ways: its contribution to climate change, its negative impact on wildlife and environment, and its detriment to our own public health. Also, I have grasped some knowledge on how circular economy works, how this system will positively affect everyone’s lives, thereby achieving a more sustainable future. Aside from reduction of raw material imports causing environmental pollution, using circular economy creates new green industries and work opportunities and will also naturally preserves natural resources.
