Waste power station Amsterdam In Europe, plans are afoot to promote waste power generation with a view to realizing a low-carbon society. In terms of generating efficiency improvement, Japanese incinerators have been superseded by their European counterparts. Here is a waste power station I visited in Amsterdam, Netherlands. This is one of the most efficient waste incinerators in Europe. Contributing to a low-carbon society through waste power generation Rational design philosophy of Amsterdam City Waste power station in Amsterdam, Netherlands. It routinely achieves generating efficiency of 30% (photo by Masaru Tanaka) Waste to Energy Facility- Fair Fax, Virginia, USA In USA, many of the incineration facilities produces power by burning solid waste. One of the facility in Fair Fax, Virginia, burns 3000 tons of waste and generation capacity is 79000KW. This waste power generation consumes 15% of the energy that is produced and sells 85% to power company which the amount is for approximately 75000 households. Many of the states in USA, waste energy from plastic waste are also been accepted as renewable energy.

62012 Study on reduction of marine debris generation on the Sea of Japan coast *Shin Sato, Koki Nishizawa, Tetsuji Arata, Tomomichi Kobayashi, Makoto Okazaki, Haruo Matsumura, and Masaru Tanaka Tottori University of Environmental Studies 1-1-1 Wakabadai-kita, Tottori city, Tottori pref., 689-1111, Japan *Contact person: s-sato@kankyo-u.ac.jp INTRODUCTION As long as human being is facing a noticeable situation that huge amount of man-made solid wastes has endlessly released to ocean and caused a marine pollution, marine debris should be one of the serious issues for all of us living in surrounding countries in the Sea of Japan. Unfortunately, citizen s consciousness and carefulness for marine debris are actually laying in different status in different countries, and the priority of marine debris to be solved as the international subject is not on stage. However, people who are residents in coast line of the Sea of Japan in Asian countries are responsible for understanding present condition for marine debris, and need to share information about the current situation each other. In Tottori, large amount of artificial waste drifters have come to the coast line every year, has damaged beautiful scenery of the historical hot spots for sightseeing as Tottori sand dune. Medical wastes and plastic bottles containing strong acid have been found on the beaches and the negative impacts have also given threat elements to general citizen. Therefore, management and disposal of marine debris as well as municipal solid wastes has been an important mission for us. This provoked us to start our research for reduction of marine debris generation. Our study consists of four research elements shown in figure 1. Application of 3R principal, reduce, reuse, and recycle on managing general solid wastes is expected to be an optimal and final goal to control marine debris generation. 1. Investigation for generation sources of marine debris; Analysis of the drift route using satellite transmitters. 2. Investigation for current state of marine debris; Analysis of physical composition of marine debris at fixed points on the western coast of the Sea of Japan as well as solid wastes in the sea bottom. 3. Promotion of education for reduction of marine debris generation; Development of education tools for school children, general public, and fishermen. 4. Establishment of recovery and disposal rules for marine debris; Development of appropriate instruction in local ports. - 126 -

Investigation of the generation sources Education for reduction of marine debris Marine debris issue Investigation of the current situation Establishment for recovery and disposal system Fig. 1 Image in our research outline 1. Investigation for generation sources of marine debris. The objectives of this study are to find out main generation sources of marine debris and to track drifting debris in the sea. Identification of places where man-made solid wastes are released can help us not only to reduce generation of marine debris but also to control beach cleanup strategies effectively. Since any general research method to chase floating marine debris has not been established yet, we began to set up methodology available for tracking marine debris. We proposed floating devices, slightly modified plastic bottles equipped with transmitters. In the preliminary experiment, we tested three different types of transmitters. Each artificial object springing radio wave was released to the sea, and then location data was analyzed. By a couple of initial trials, we finally selected a floating device equipped with a mobile-phone type transmitter working on the ocean environment. Next, release places in Tottori prefecture were determined. Fixed points at river mouths of Hinogawa, Tenjingawa, and Sendaigawa were chosen from the west, central and east part of Tottori, respectively. We released the transmitters containing plastic bottles in each fixed point every month during seven months in a year and then every drift route in the sea was analyzed. The results demonstrated that more than 70% of the transmitters released from Hinogawa river in the west and Tenjingawa river in central area came back to Tottori Fig. 2 The plastic bottle and the transmitter used - 127 -

area again. This result suggested effect of landform in the coast line. In contrast to these two rivers, more than 50% of transmitters thrown from Sendaigawa river went away and only 40% of them stayed in Tottori. The plastic bottles gone out of Tottori area washed up to coastline in Hyogo, Kyoto, and Tohoku region. We found that Aomori and Akita prefecture were final destination of the plastic bottles. In 2011, great east Japan earthquake occurred in Tohoku and the massive marine debris brought by Tsunami generated in the ocean. Based on the serious situation, we changed research direction to tracking drift route of Tsunami debris. In this experiment, we newly applied large PET bottles equipped with special transmitters to obtain global positioning data. Last June, October, and January, the transmitters have been released from Miyako in Fig. 3 An example of drift route to coast in Iwate prefecture, Kesennuma in Miyagi Akita after 1.5 month 17 Oct., 2011 Fig. 4 GPS transmitter-containing PET bottle Released in 3 June, 2011 Fig. 5 Footprint of the GPS-PET bottle in Pacific Ocean prefecture, and Soma in Fukushima prefecture to Pacific Ocean. Figure 5 indicates that transmitters from different release areas have moved to each different direction, suggesting difficulty to predict correct drift route of Tsunami debris. Currently, our advanced group is going to make international research collaboration with experts in Hawaii for tracing Tsunami debris. 2. Investigation of current state of marine debris. To understand current state of marine debris, we should investigate when, where, how, and what marine debris have drifted ashore on beaches. Also we need to find what the effective methods are. When we obtain the correct data through our investigation, the information can be utilized for education to reduce marine debris generation toward children, general public, and fishermen. - 128 -

In this research, we considered two approaches to assess state of marine debris. For small scale, hand-pick investigations of marine debris on beaches and in the sea bottom were carried out. We selected ten fixed points along the coast line Fig. 6 Physical composition of marine debris on the beach and in the sea bottom in Tottori area based on different beach characters. For practical work, 2-3 frames (10m X 10m) were set up on every beach in ten fixed points. The same size and number of frames were placed in same position every time. After preparation of the defined frames, marine debris were collected, separated in 8 material types, and analyzed on the basis of wet weight, number, volume, and nationality. For practical work in the sea bottom, artificial solid wastes were collected with trawl net, and then analyzed as same as the beach method. Figure 6 shows the physical composition of marine debris in wet weight on the beach. This result from summary of four times investigation through a year in 2009 demonstrates that 63% of all marine debris was plastic. 62% in the sea bottom was plastic too. Rubbers, polystyrene form, and ceramics were also found as solid wastes. Over 90% of marine debris was occupied by these four materials, indicating that control of man-made solid wastes from citizen s activities might be a key to reduce marine debris. Artificial marine debris of quantity which cannot be disregarded came from oversea. Although almost 70% of PET bottle, plastic container, and fishing gear are from domestic area in Japan, 20% of PET bottle, 12% of plastic container, and 4% of fishing gear might be from Korea. In addition, 11% of PET bottle, 7% of plastic stuff and 11% of fishing gear were suggested to be from China. PET bottles written in Russia have been found as well. When considering the fact, solution of marine debris issue requires sharing the correct information beyond countries and international strategies to prohibit easy disposal of solid wastes to the ocean. In the large scale investigation, we analyzed marine debris utilizing photo image from a space satellite and a helicopter shown in figure 7. Marine debris in a spot on the beach was assessed and the data were compared with the results obtained in the small scale experiment. In this research, photo image analysis Fig. 7 Investigation of marine debris in a large scale - 129 -

resulted in little consistency with the analysis data from small scale. This method didn t work when we conducted quantitative analysis of marine debris on small area, but it could be valuable for estimation of relative amount and size of marine debris covering an area. This method might also be effective when estimating marine debris locating in a spot on the coast where people can hardly access. 3. Promotion of education for reduction of marine debris. As the evidence shown above, most of marine debris issues attributes to human activities. To reduce marine debris comprehensively, education seems to be simple but most practical and effective method. This research herein focuses on promotion for spread education to general public and fishermen as well as school children. Development of educational tools available whenever and wherever we need was our task to Fig. 8 e-learning DVDs for education achieve this project. The e-learning DVD materials consist of motion pictures and illustrations in 13 to 18 min. The contents of the DVD were modified and optimized for different learners, school children, general public, or fishermen titled as calling back beautiful coast: marine debris problem and how to solve it. In addition to digital educational tools, development of practical education materials by university students was also considered. The short drama for marine Fig. 9 Student s initiative for education to kids -learning DVD for education debris problem partially followed by a Japanese fairy tale, Urashima Tarou which every child has known already as well as simple fishing games consequently attracted children s attention through the event. It was also demonstrated that the student s effort gave school children extra awareness to environmental issues except for marine debris. E-learning DVDs to promote reduction of marine debris has been prepared in Korean and English. We hope that educational tools we developed can be used for children in many foreign countries. 4. Establishment for recovery and disposal system of marine debris. Marine debris floating or sinking in the sea are considered to increase year by year, might affect fishing activities for professional fishermen. In fact, our previous investigation demonstrated that large number of artificial solid wastes has sunk in the sea bottom. Based - 130 -

on the results, it was expected that establishment of the recovery and disposal rules in a port could lead to taking evasion of danger during fishing and safer fishing itself. As long as practical recovery of marine debris has been depend on each fisherman, we initially tested effective social models for recovery of marine debris in the port of Sakai Minato supported by Tottori fishery association. Fig. 10 Typical solid wastes pulled up to a fishing boat Fig. 11 Questionnaire about marine debris to local fishermen In the beginning experiment, actual condition of unnatural solid wastes lying in the sea bottom near Sakai Minato area was analyzed. Figure 10 shows typical man-made solid wastes pulled up to a fishing boat. The composition of the artificial solid wastes was mostly occupied with plastics, and the amount fishermen brought to the port was almost 3 kg/ person in every fishing activity. The results from frequent interview and questionnaire to local fishermen suggested that most of fishermen could be highly motivated if there is a format for a buy rule of solid wastes recovered by business fishing. Alternatively, it was also highlighted that the administration office in local government doesn t have enough revenue to treat marine debris as same as municipal solid wastes. Financial support could be one of most important factors for removal of marine debris from ocean. CONCLUSION It was found that quite complicated factors are involved in current issues of marine debris across borderlines among countries. Change of our thought and consciousness in general public and fishermen should be an important key for solution of this issue. However, the present situation may still be behind spotlight for general people. Near the future, we hope further effective ways to allow general people to notice seriousness of marine environment polluted by man-made solid wastes can to be developed.
