Since the human being lived in this world, different kinds of waste were produced continuously. In the early years, the common wastes produced were biodegradable. There are no major problems with this since it will decompose over time. As the number of population increases and new inventions were made, the kind of waste produced by humans also increases. Some of these wastes include plastics, glass, metal, papers and many more. Some of waste scattered in the surroundings are recyclable. But due to improper waste management, these are not optimized. In the current generation, different manual systems are starting to be automated. Waste management was also starting to follow the trend. In other countries, there are automated systems that perform the collection of waste. There are also machine that performs recycling of some waste products. But before the process of recycling, waste must be segregated first. Waste segregation is done by separating the garbage according to their classification. With numerous kinds of technologies, implementing a system that will do the segregation of waste becomes possible. Conveyor systems and sensors are common technologies used in industry. A conveyor belt or a conveyor is a continuously moving strip which is used to move objects along. This tool is commonly used in large factories for transferring materials. Sensors, on the other hand, are devices that detect the presence or absence of an object, or certain properties of that object, and provide feedback. There are other different kinds of sensor that perform different functions. These technologies when combine with other technologies will surely lead to inventions of new machines not only for segregating waste but also for different purposes. 1.1 Background of the Problem
Waste, has remained to be the most visible and dangerous environmental problem in the country. Due to a growing population, rapidly increasing consumption and increasing urbanization, waste generated in the Philippines is estimated at 35,000 tons per day. According to some reports, Metro Manila produced about 8,400 to 8,600 tons of trash per day. That volume already accounts for about 25 percent of the country’s daily solid waste generation. [ALVE2011] Despite of the large volume of garbage in the country, only 12 percent of the waste is recycled and re-used per year. That 12% of recycled wastes are comprises mainly of the materials sold to the junk shops. The low percentage of reused and recycled materials is due to non segregation of waste. Trashes are dumped altogether in landfills and leave the segregation part to the people living near the dump site. In that way of living, a statement “there is money in garbage” becomes popular. This statement was proven by numerous businesses that earns from trash. Junk shop is an example of that. This kind of business operates by buying recyclable materials from scavengers and sold those things to the manufacturer of the product. Waste segregation is essential in that kind of business. The operator manually grouped the materials whether it was paper, plastic or metals and calculates its weight to be ready for selling. It takes too much time and effort doing the job. It will be a great help if there will be a machine that can help in sorting those garbage and weigh it automatically. 1.2 Overview of the Current State of Technology
Selo’s Junk Shop is a large scale junk shop that is operated by Miranda. For 20 years, they have been in the business of trading and selling segregated waste such as metals, papers and plastics to other bigger manufacturing companies and recycling factories. 1.3.1 Foreign Studies
Selo’s Junk Shop took a long time to complete the whole process of the usual junk shop. From collecting to segregation and then weighting to packing, these are the parts of the system that requires human intervention and efforts. All these process were done manually up to inventory of...
