Topic: Sustainable Waste Management Technology And Environmental Economics

Description: With the increasing urbanization, waste management is a major global issue that governments face daily. The population and overpopulation brought about generation of waste and that has been causing negative impacts on our environment. Waste reduction and valorization need to be taken to the next level. Sustainable waste management technology is a key concept of the circular economy and offers many opportunities:1. Economic: Waste management involves collecting, sorting, treating, and recycling and when properly facilitated through chemical, mechanical or thermal methods, providing a source of energy, raw materials and other resources. Therefore, it has a huge economic potential that needs to be leverage by the public and private entities. On this reason, recycling of these wastes may save importations and foreign exchange.2. Social: Better quality of life for local populations, by improving hygiene conditions and reducing health risks-related and to reduced illegal dumping of waste couple with inadequate garbage/ waste collection. 3. Environment: To lessen the impact on the environment, by improving our water quality and contributing to the reduction of greenhouse gas emissions. Besides that, it helps by reducing biodegradable and non-biodegradable wastes; it also helps in reducing the heavy environmental cost of producing more by polluting. Once collected, municipal solid waste may be treated in order to reduce the total volume and weight of material that requires final disposal. Treatment changes the form of the waste and makes it easier to handle. It can also serve to recover certain materials, as well as heat energy, for recycling or reuse.

Economic and environmental benefits of waste metal recycling in Lagos State, Nigeria: Perceived perspectives.

The present study assessed the economic and environmental benefits of waste metal recycling in Lagos State, Nigeria. In our society today, recycling has become more and more prevalent as landfills everywhere begin to reach capacity. Scrap metal is a prime example of a win-win recycling situation. Both man and Mother Earth benefit when old metal scraps are given a second life. Multistage sampling technique was employed to administer 50 copies of structured questionnaire to companies and individuals involved in waste metal recycling. Data obtained were analyzed using means and One-Way Analysis of Variance ANOVA . The result obtained revealed that above 85% of the respondents stated that waste metal recycling ensure resource conservation and sustainability, protect the environment from damage and save energy. Also, above 90% of the respondents stated waste metal recycling create job opportunities, save industries the costs of sourcing material and energy and promote economic development opportunities. ANOVA result revealed that economic benefit of waste metal recycling did not vary significantly across ages F = 1.029, p&0.05 , because respondents across ages know the economic benefits accruable to them. The study recommended the need for government to encourage waste metal collection by creating ready markets establishment of state owned recycling companies for scavengers of waste metals
