Moreover, government policies on the environment are a piecemeal where they exist, and are poorly implemented. Public enlightenment programs lack the needed coverage, intensity, and continuity to correct the apathetic public attitude towards the environment. Solid waste management is the most pressing environmental challenge faced by urban and rural areas. Despite a host of policies and regulations, solid waste management in the country is assuming alarming proportions with each passing day. Most of the wastes are generated by households and in some cases, by local businesses, University fraternity, artisans and traders who litter the immediate surroundings.
The main areas to be concentrated on waste disposal are segregation and recycling. Only when the waste materials are segregated, the industries will find it easier to send the segregated materials for recycling process. The objective of this paper is to segregate industrial wastes like magnetic metals, non-magnetic metals and other wastes such as plastic, glass etc., by means of sensors which will help the industries to work
The sharp increase in the volume and diversity of waste materials generated by human activity and their potentially harmful effects on public health and the environment, presents the need to adopt scientific methods for safe disposal of wastes and for the conversion of wastes to productive uses such as energy generation. This does not advocate for the generation of more wastes but places emphasis on the utilization of waste that cannot be absorbed through the institution of waste minimization, recycling or composting programmes, NEPA (2010). The aim is to focus on disposal of residual waste in a safe and environmentally‐friendly manner through its conversion into
Waste is any substance or material which is discarded when it is not useful anymore. Compared to the most commonly used methods such as recycling, waste transformation and source reduction in managing solid waste, sanitary landfilling has been identified as an appropriate method to eliminate waste in an economical and environmental friendly manner. However, finding a suitable area for siting a landfill is challenging due to incorporation of various factors and regulations. As the rate of people migrating from rural areas to cities is increasing, thus cities are expanded and therefore result in more waste production. For example, the Akure city which have developed and the number of waste has increased.
A portion of that waste stream is infectious or potentially infectious and presents a potential hazard to the public health and the environment. Hospital waste is generated during the diagnosis, treatment, or immunization of human beings or animals or in research activities in these fields or in the production or testing of biological. It may include wastes like sharps, soiled waste, disposables, anatomical waste, cultures, discarded medicines, chemical wastes, etc. These are in the form of disposable syringes, swabs, bandages, body fluids, human excreta, etc. This waste is highly infectious and can be a serious threat to human health if not managed in a scientific and discriminate manner.
The presence of hazardous waste in the environment is often the result of inadequate disposal. Improperly maintained landfills are a major issue. Although they appear to be isolated from contact with people or resources, they can still contaminate the surrounding environment. Waste in landfills sits for years or even generations. It emits gases that are both foul-smelling and toxic.
Hazardous waste: Some share of generated waste includes the hazardous wastes which is harmful for environment if necessary cares do not considered after usage of them, normally the definition of the hazardous wastes are the same within all aviation business based on the reports and information of the producers and suppliers. Hazardous wastes are including used oil of different part of every aircrafts, some types of lubricants and chemicals, batteries, components and items at security and redundant Electronic and electrical equipment. Some of the hazardous waste must only be removed by Hazardous waste specialists like the radioactive instruments which may cause radiation danger. Almost all hazardous waste has their special waste management
The threat of disease from solid waste mismanagement is ever lasting. It reduces workers productivity, keeps children out of school, lowers resistance to shocks and etc. These put poor under severe financial strain and deprive opportunities to improve their standard of living. As a result, improper solid waste management has very high economic, environmental and social costs that have not been seriously considered by economic agents. Like the others developing countries, solid waste management is a serious confront to Ethiopia.
Hazardous or toxic waste can also be created by individual’s, health-care facilities, and small businesses. And addition to manufacturing locations, scientific laboratories farms, and medical, construction sites, hospitals and other health care centers, and private homes are involved in the production of this waste around the world. At homes; batteries, computers, and paint products provide just a few examples of products that can create poisonous waste dangers. Waste can infect any creature with any form it takes solid, liquid, gas, and vapor. Industrial activities includes any material that are useless during a manufacturing process has been throw away into the ocean, rivers, lacks, or even land.
