Solid Wastes Disposal Control Video Lecture | Biology for JAMB

Ans. Solid waste disposal control refers to the management and regulation of the handling, treatment, and disposal of solid waste materials. It involves implementing measures to minimize the environmental and health impacts associated with the disposal of solid wastes.

Ans. The main objectives of solid waste disposal control are: - To protect human health and the environment from the harmful effects of solid waste - To promote the sustainable management of solid waste by reducing waste generation and promoting recycling and reuse - To ensure the proper handling, treatment, and disposal of solid waste in a manner that minimizes pollution and environmental degradation - To enforce regulations and guidelines for the safe management of solid waste - To promote public awareness and participation in waste management practices.

Ans. Common methods of solid waste disposal include: - Landfilling: This involves burying the waste in designated areas and covering it with soil to minimize odors and prevent pollution. Landfills must be properly designed and managed to prevent groundwater contamination and methane gas emissions. - Incineration: Waste is burned at high temperatures, reducing its volume and converting it into ash and gases. However, incineration can release harmful pollutants into the air and requires appropriate air pollution control systems. - Recycling: Materials such as paper, glass, metals, and plastics are collected, processed, and transformed into new products. Recycling helps conserve resources, reduce waste generation, and minimize environmental impacts. - Composting: Organic waste, such as food scraps and yard trimmings, is decomposed in a controlled environment to produce nutrient-rich compost. Composting is a natural way to recycle organic waste and improve soil fertility. - Waste-to-Energy: Some waste materials can be used as a fuel source to generate electricity or heat through processes like anaerobic digestion or gasification.

Ans. Some challenges in solid waste disposal control include: - Inadequate infrastructure and resources for waste management, especially in developing countries. - Lack of public awareness and participation in waste reduction and recycling practices. - Improper waste segregation at the source, leading to contamination and reduced recycling potential. - Limited availability of suitable landfill sites, especially in urban areas. - Environmental and health risks associated with certain disposal methods, such as landfilling and incineration. - Increasing waste generation due to population growth and consumption patterns. - Illegal dumping and improper disposal practices, leading to pollution and environmental degradation.

Ans. Individuals can contribute to solid waste disposal control by: - Reducing waste generation: This can be done by practicing mindful consumption, avoiding single-use items, and opting for reusable or sustainable alternatives. - Proper waste segregation: Ensuring that waste is properly sorted into recyclables, organic waste, and non-recyclables can facilitate recycling and composting processes. - Recycling: Actively participating in recycling programs by separating recyclable materials and disposing of them in designated recycling bins. - Composting: Composting organic waste at home or supporting community composting initiatives can divert a significant amount of waste from landfills. - Responsible disposal: Making use of designated waste collection services and facilities for proper disposal of non-recyclable and hazardous waste materials. - Spreading awareness: Educating others about the importance of waste management and sharing knowledge about sustainable practices can help create a culture of responsible waste disposal.
