Under the government's principle of paying for emissions, the RFID-based pay-as-you-go system, which charges fees in proportion to emissions, was fully implemented in 2012. As of the end of 2018, the penetration rate is about 40% based on 149 local governments and multi-family apartments nationwide. The introduction of equipment showed a reduction effect of about 20-30%. Problems with existing equipment also began to appear. This study tried to improve by applying and integrating the existing technologies to solve the fundamental problems of these inlets. In other words, the plan is to improve the environment around the food waste meter by changing the design so that the hopper goes deep into the food waste bin inside the food waste meter so that the food waste becomes full and is designed smoothly when replacing the collection container.

This paper estimates the price of standard waste bags that satisfies the polluter pays principle. Unlike previous studies, this paper suggests a method that can find new equilibrium prices using a structural relationship between the demand and cost function for the wastes. To do this, we employ the fixed-point iteration. The main findings of this paper are as follows. Assuming that the polluter pays principle is achieved at the average cost for the waste treatment, the price need to be set at a level about 3.12 times higher than the current one. The estimation result using a structural model, however, shows that the price should be set at a level four times higher than the present. This results are because the quantities reduced of the wastes make the cost per quantity of wastes due to the fixed costs increase. If applying the estimated price to the demand function, the amount of discharge of waste generated nationwide can be reduced by 10%.

This study proposes an NFC-based payment system that considers user convenience while expanding the existing payment method for RFID-based individual food and logistics waste equipment. In line with this trend, I proposed to apply NFC to the existing RFID-based food meter to release the food in the meantime and to address the problem of re-carrying due to card loss, card not possessed, and non-filling, and the question that could not be identified by various cumbersome procedures. NFC's function alone has been certified for its convenience, which led to its introduction and research in the period of time. Of course, we need to negotiate fees with the transportation card company, but if we see a market share related to transportation card soon, we think smooth negotiations will take place. NFC method will be expanded to all phones with iPhone NFC opening. Therefore, in the next study, we intend to apply the payment system in NFC by linking with local currency, mobile vouchers, and card companies, which are being paid as respective payment means according to the recent emergency support system for COVID-19.

The average volume of waste per a person in Korea is exceedingly higher than that of Europeans. But the social movement for the resources recycling and the environmental conservation makes the people play their part in several activities like the Separate Collection System. At the time of this agitation, Korean central government brought the Volume Based Waste Charge System into operation in some regions on a trial basis having full-scale operation nationwidely near at hand. Andong City which is one of points under trial operation had remarkble result during this term in resources recycling as well as wastes reducing. The wastes' diminution reached to 32.0 % and the resources recycling was increased by 13.7 times. The responses from the 701 housewives in Andong were also very stimulative. The neccesity of this system was judged conclusively by 91.6 % of total answerers. Also this system was considered as a successful one by 78.4 % popular support. But not little portion (53.8 %) of the answerers felt that the detail methods of this system were unconvenient. In order to take root this system in it's early stages, the Separate Collection should be carried out perfectly and systematically with top priority. And the next program should be the improvement of the detail methods in this system.
