Smart Waste Bin Using AI, Big Data Analytics and IoT

Two SFU Mechatronics Systems Engineering engineers created an AI-powered smart recycling machine that will revolutionize waste management and enterprises. While sorting and sending garbage, the intelligent bins should reason for themselves. All that is required is for the trash to be deposited in the appropriate waste bin. Before determining what to do with the garbage, the bin uses its sensors to inspect and equate the trash retrieved in previous trash records. Depending on the decision, the garbage is directed to the appropriate disposal system, such as a landfill or a recycling facility. We can expect a substantial reduction in waste generated globally if we find better ways to dispose of and recycle trash. This will go a long way toward preserving the environment for a more prosperous and sustainable future.
Recreational Environment and Swimming Areas

Solid waste includes garbage, refuse, sludge, rubbish, trash, and discarded materials and can either be non-hazardous or hazardous. Non-hazardous waste which will be discussed here includes packaging, newspapers, disposables, food waste, plastic, wood, glass, metal cans, incinerator ash, etc. Cruise ships generate large volumes of solid waste. For example, one cruise ship with 2500 passengers and 800 crew members can generate 1 ton of garbage a day. It can also generate thousands of pounds of glass and cans per week as well as a large amount of dunnage, which is packing material to protect and support cargo in the ship’s hold, as well as all the packaging material used around the ship. It is estimated that a cruise ship can generate 70 times more solid waste each day than a cargo ship. Solid waste improperly handled and discharged to the ocean, litter thrown into the water by passengers, or things such as towels, clothing, plastic bottles, cans, etc. blown overboard, create a serious environmental impact on the ocean or fresh bodies of water and may have a detrimental effect on sea life. Plastics are especially a problem since they accumulate on the surface of the water and on beaches. Birds, fish, turtles, and even marine animals may be seriously affected. Garbage can increase the biological oxygen demand and chemical oxygen demand, increase turbidity, and increase nutrient levels in the water. The ash from incineration may be toxic in nature to sea life.
Energy Sources: Renewable versus Non-Renewable
Published in Brian D. Fath, Sven E. Jørgensen, Megan Cole, Managing Air Quality and Energy Systems, 2020
Wastes, which include recovered materials and energy that would otherwise be discarded, are also sometimes considered as an energy source in the category of non-renewable energy. Wastes can be used directly as energy forms or converted to more useful forms. Waste materials and waste heat can be recovered for utilization both within a facility and in other facilities where they are needed. For example, waste heat from hot gases (e.g., stack gases) and liquids (e.g., cooling-water discharges) can sometimes be recovered. Also, material wastes can be used in waste-to-energy incineration facilities, which burn garbage to provide heat and to generate electricity. Utilizing such wastes offsets the need for further supplies of external energy.
Development of Bacteria biofertilizers using locally isolated rhizosphere populations and agricultural refuse and their impacts on growth of local test crops

The global population is estimated at over 7.7 billion and is set to grow to 9 billion in 2050, and rapid urbanization has led to greatly intensified agricultural activities for enhanced food production (Giller et al. 2021). Agricultural activities generate many by-products, including fruit bark and stems, predominantly composed of cellulose, lignin, and hemicelluloses (Zainudin et al.2022). They become major environmental pollutants, release unpleasant smells, are connected to contaminating surface and ground waters, soil, and atmosphere, and have negative impacts on public health (Duque-Acevedo et al.2020). Although these by-products are resource-rich, the inability to reprocess them means they persist in the environment as pollutants. Recycling of wastes reduces the unpleasant odors of garbage, benefits sanitation and public health, and can enhance soil fertility.
A novel biomethane (BMP) and composting (CMP) potential framework for determining biogas and composting potential of urban organic waste

Numerous countries, especially those in the developing world, face significant waste management challenges. As a developing nation, Ghana has various obstacles in managing waste in urban areas [9]. Existing waste management methods generate insufficient revenue, which contributes to solid waste management issues. This recurring challenge will stay unsolved unless there is a paradigm shift in trash management, from viewing garbage as a burden to viewing waste as a resource, creating a new field of research known as waste-to-resource. Waste-to-resources has two primary benefits for garbage management: (1) it reduces greenhouse gas emissions by diverting less waste from landfills; and (2) it generates economically useful resources from wastes, such as clean water, fertilizers, or renewable energy. Simply, waste-to-resources transforms waste management difficulties into an opportunity to spur economic growth and development.
Hydraulic and mechanical behavior of landfill clay liner containing SSA in contact with leachate

A garbage sanitary landfill is the main method used for garbage disposal. In recent years, leachate leakage and structure instability have frequently occurred in landfill clay liner systems. Landfill leachate is a type of wastewater containing high concentration of organic mixtures that may be highly toxic and difficult to be degraded. Once the landfill liner layer is damaged, the leachate leakage necessarily contaminates the soil and groundwater, thereby posing a threat to human life [1]. Sludge with the high content of organic matter is a by-product of wastewater treatment, and easily stinks. Thus, without harmless treatment, sewage sludge contaminates environment [2]. Up to now, there are few researches in the resource utilization of the sewage sludge.
