  • Development of “Amamizu Drink” as a Tool for Awareness regarding Rainwater conservation, and Investigation of the Effectiveness of Different Label Designs Reviewed International journal

     More details

    The Sustainable Development Goals (SDGs) adopted at the United Nations Summit in September 2015 included water-related goals. However, rainwater is not recognized as an important resource in Japan. To address this issue, “Amamizu Drinks,” which involve a non-routine experience of “drinking rainwater,” were developed as tools for creating awareness regarding rainwater conservation. Additionally, three types of label designs were created, and their effectiveness in developing rainwater awareness was investigated. As a result of the survey, label designs with handwritten illustrations were found to be the most preferred, and the color evaluation was particularly high. Based on these findings, further research is needed to identify the elements required to enhance awareness of rainwater and develop effective environmental education materials as teaching aids. The results of this study can contribute to promoting a sustainable society by encouraging individuals to recognize the value of rainwater as a vital resource.

    In Akashima, one of the Goto Islands in Nagasaki Prefecture, which is a remote island with no
    groundwater, rainwater is used as domestic water. In order to improve the quality of rainwater to use, it is necessary to collect a wide variety of data on the amount of rainwater and the usage of water in the area. In this paper, we describe a rainwater utilization system using LoRaWAN, one of LPWA (Low Power Wide Area) introduced in Akashima.

     More details

    Akashima island, Goto City, in the Nagasaki Prefecture of Japan is a small island (0.54 km2) with approximately 10 residents. The island is the only island in Japan where all domestic water is supplied by rainwater harvesting. The Fukui University of Technology has been implementing the Akashima Revitalization Project since 2016, aiming at the sustainable development of Akashima. As part of the project, a survey on rainwater usage was conducted in Akashima. The survey results indicated that the quality of the stored rainwater was relatively good, and there were no issues with simple filtration and sterilization. The daily water consumption per person was between 50 to 60 L, approximately a quarter of the water used by people living in a general city with water supply (219 L).

    Mn化合物にBi化合物を添加して焼成し、水溶液中のヒ素に対する吸着剤を合成した。最大吸着量は50mg/gに達し、さらにpH依存性、実ヒ素廃水への適用、脱着による繰返し利用の可否について検討した。その結果、これまでのヒ素吸着剤と比較して遜色のない結果が得られた。さらに、実用化に向けた研究として、カラム法やパック法による水溶液中ヒ秦の吸着除去試験と再生利用についての検討を行った。その結果、これらの方法によって1~20mg/lヒ素含有水から連続的にヒ素を除去できた。
