Classified Image

Earlier, separation of waste objects was a tedious process for humans since it requires thorough identification of each object’s nature. The identification and segregation of waste products are indispensable processes. The project consists of an Image Classification section where the waste is captured with the help of Raspberry pi camera and processed in the appropriate environment to classify if the waste is biodegradable or nonbiodegradable. The classified image is set with a key and delivered to the breadboard which is connected with Raspberry pi to illuminate the LED accordingly. The untrained or unidentified object is marked with a different LED and can be left for a new training process so that the system collects the features of the particular object and be ready with a model. Following is the Waste Management System. An Ultrasonic sensor is placed at the corner to dump the waste in the corresponding bin with the help of servo motor, which contributes to swap the bins by rotating itself in 180 degrees when non-biodegradable waste is identified. The classified object is disposed in its bin which concludes both the classification and segregation processes. Manual labour is minimized through this automatic waste identification and disposal

Garbage can be interpreted as a consequence of the activities of human life. It is undeniable, garbage will always be there as long as life activities continue to run. Every year, it can be ascertained that the volume of waste will always increase along with the increasing pattern of public consumerism. The landfill which is increasingly polluting the environment requires a technique and management to manage waste into something useful and of economic value, Bantas Village, Selemadeg Timur District, Tabanan Regency currently has a Waste Management Site (TPS3R) managed by Non-Governmental Organizations (KSM ) The source of waste comes from Households, Stalls, Restaurant Entrepreneurs, Schools, Offices and Ceremonies which are organic and inorganic waste. The waste management system at Bantas Lestari TPS with 3R system is Reduce (reduction of waste products starts from the source), Reuse (reuse for waste that can be reused) and Recycle (recycling waste) to date it is still running but not optimal. The method used in this research is descriptive quantitative with data analysis using SWOT analysis. This study produces a Waste Management Strategy which is the result of research from the management aspect, aspects of human resources and aspects of infrastructure facilities.

Waste Pickers

All recycling in India is undertaken by (and via) the informal sector. This sector includes waste-pickers, small middlemen, transporters, larger middlemen and Anally, reprocessors. These self-employed people play a very important role in urban waste management as they provide a service which the urban municipalities cannot provide given their current institutional framework. Although the sector of informal waste managers is critical to solid waste-handling in India, the sector is unable to optimise its work due to lack of social legitimacy or legal rights over waste-processing, which makes it vulnerable to intimidation. Additionally, due to lack of awareness and specific skills, as well as very poor working conditions and poor access to basic facilities, this sector has so far been unable to make its recycling efficient and profitable. With certain changes in the policies relating to recycling and ownership of waste, there can be a synergetic relationship between the recycling sector, the existing relevant laws, and waste-handling in India that can significantly improve the efficiency of the sector and enhance financial returns to the waste-pickers and reprocessors. Such policy changes as provision of legal rights over solid waste to waste-pickers and organisation of waste-pickers into cooperative groups, can further the interests of these marginalised groups and maximise their profits, in addition to substantially improving solid waste management in the city.

This qualitative study explored the management of waste in commercial and training dental laboratories in order to determine the practices and attitudes of dental technology practitioners and academics towards reusing and recycling dental laboratory waste products, and alert them to the benefits of waste management on the environment. The research objectives were to establish and report on the extent of waste management that entails waste reduction through reusing and recycling, to uncover alternative uses for dental laboratory waste and the possible economic benefits thereof and to influence dental technology industry on environmental sustainability. The research project was conducted in the interpretive paradigm. In the course of this study dental laboratory owners, dental technicians/technologists and academics from the dental technology programme at a training institution were interviewed. Waste handling in dental laboratories was observed in order to gain greater insight as to current practices in laboratories. Thematic content analysis was employed to analyse the qualitative data. This study found that waste management was poorly understood and practiced amongst the dental laboratory owners, dental technicians/technologists and academics. The study adopted a waste management hierarchy conceptual framework which was influenced by the Waste Act (Act No. 59 of 2008). The negative attitudes towards responsible waste management practices and the poor understanding of waste management by dental laboratory owners, dental technicians/technologists were found to be as a result of the poor understanding of the possible impact that waste from dental laboratories can impose on the environment. The perceived lack of participation in constructive waste management legislation by the South African Dental Technicians Council was also seen to be a contributing factor to the negative attitudes towards responsible waste management practices within the industry. This finding reinforced the finding that the dental industry has no knowledge, understanding and desire to understand waste management and, more importantly, to understand that one does not practice things solely for legislative reasons but that there are economic as well as environmental reasons to practice constructive waste management. On the other hand, this study found that the industry was not averse to engaging in environmental friendly practices provided there is financial gain. This was established after the benefits of waste management practices were explained to the industry.

This study aimed to examine the impact of poor solid waste management on student’s health care at Gondar University of “Tewodros” campus. The study used a mixed-method approach. To recruit sample respondents', both probability and non-probability sampling methods have been employed. In the meantime, the study revealed the sources of solid waste, it is understood that the poorly collected and managed solid wastes of the study area due to the lack of necessary materials and facilities of waste collection, lack of laborers engaged in street sweeping and daily removal of solid waste is now becoming the major causes of environmental problems such as surface and groundwater pollution problems. Besides, the student’s health office personnel in the interview approached the general health status of the students on the campus during this year. Accordingly, dysentery, common cold, and typhoid are the most frequently appear disease on the Tewodros campus. Therefore, there should be a “students committee “at the campus level to control illegal dumping and to develop practice and habits of poor waste handling and disposal in the community, and there must be apparent regulation and policy frameworks that prohibit poor waste management.
