Awareness of the nature has a limited capacity and the consideration that the future generations are in danger due to the rapid waste with the development of technology in the last century, is leading to sustainability and green building design concept. The hazardous effects of the industrial materials are coming out, thus, healthier, natural materials and production methods are being discovered to design healthier interior environments. Architectural acoustics requirements are one of the vital topics to provide healthy and comfortable environments. The materials that are consumed in Turkey to provide acoustical comfort requirements in terms of room and building acoustics are commonly synthetic fibers, such as glass wool and rock wool or perforated materials consisting of those fibers. The preference by architects is mostly smooth, unperforated and plain sound absorbers because of aesthetic reasons. This kind of materials frequently imported from other countries with high costs and yet, that are supported with synthetic fibers. Rock wool and glass wool are hazardous for respiration; furthermore physical touch may induce itching. Moreover, synthetic fibers, such as glass wool and rock wool are produced with high energy demands in addition to transportation costs which result in high carbon footprints. The investigation of ecological and natural materials is indispensable to provide acoustical requirements considering the health and energy efficiency. This study is focused on the development of a sound absorptive material having smooth surface and ecological features. The material is made of pumice which has large reserves in Turkey and reed, which grows in wet areas such as rivers and lakes. The binding agent for the pumice is lime, which is a more ecological binder compared with cement and gypsum products in terms of energy efficiency and acoustical performance. The selected materials are found to have great potential for improved acoustical performances in addition to being economic and ecological. The measurements of the composite acoustical performance are realized with Impedance Tube.

A techno-sustainable bio-waste management strategy for closing chickpea yield gap Ozdemir, Saim; Özdemir, Serkan; Ozer, Hasan; YETİLMEZSOY, Kaan (Elsevier BV, 2021-01-01) © 2020 Elsevier LtdSustainable development goals imply environmentally sound management of all wastes to minimize the waste generation through prevention, reduction, recycling, and reuse. In particular, the poultry industry produces nutrient-rich waste that requires proper management. Additionally, the recycling of bio-wastes in agricultural lands is still a key technology for the sustainable use of nutrients as a renewable fertilizer. Currently, there are very few studies on the utilization of agro-industr...
An associational study on pre-service early childhood teachers' nature relatedness in education for sustainability Şahin, Elvan (Informa UK Limited, 2019-10-02) There is significant global concern with current environmental problems, yet people's behaviour towards the environment has been resistant to change. Young people have the opportunity to bring about desirable changes through environmental behaviours and attitudes. The goal of this study is to better understand the scope of nature relatedness as an attribution interacting with pro-environmental behaviours for Turkish pre-service early childhood teachers. We examined the associations between the domains repre...
Comparative Life Cycle Assessment of Uranium Recovery from Brine Altay, Melike Benan; Kalıpçıoğlu, Ceyda; Kurt, Zöhre (2022-06-01) With the increase in world population and the associated increase in raw material, clean water and energy demands, seeking for innovative and sustainable methods to decrease human-made environmental footprint becomes a task of utmost importance to reduce emissions and waste generation. Uranium-based atomic energy generation has an enormous potential to efficiently supply energy demand at the cost of high environmental impact on water bodies. Therefore, estimating the environmental impacts of the uranium rec...
IDS for Ideas in Higher Education Reform Onur, Selahattin (2009-06-12) Increasing technical and socio-cultural information accompanied by a fragmented specialization in knowledge and skills, rapidly changing technology, and liberal economic growth that negates rational use and distribution of world's resources challenge ecological sustainability. These challenges and concurrent trends for sustainable development, e.g., sustainable construction, motivate the IDS approach in the delivery of projects for the built environment.
Environmental Analysis of Construction Materials: Material Specifications for Green Built Environment Çakmaklı, Ayşem Berrin (IGI Global, 2019-01-01) There is a growing universal awareness of protecting the living and non-living environment and making enlightened decisions to achieve a sustainable development without destruction of the natural resources. In this point of view, selecting building materials according to their energy and health performances gains importance in sustainable design. 3Rs (reducing, reusing, recycling), and supplying a healthy, non-hazardous indoor air for building occupants are two important parameters of environmental life-cyc...
