“…Food waste and loss are increasing problems for emerging countries. The total edible food loss and waste is estimated at almost 26.04 million tons/year in Turkey (Salihoglu, Salihoglu, Ucaroglu, & Banar, 2018). Huge amounts of food are wasted because of the quality standards demanded, especially at the retail level.…”

Supply chains are composed of multiple stakeholders who have complex interrelationships. In addition, the forward and reverse flow of materials, information, human resources, and finance occurs among different stakeholders in closing the loop of supply chains. Reverse logistics (RL) activities are gaining importance in terms of size and quantity due to both economic and environmental concerns. These flows in RL in supply chains are both dynamic and complex in nature. Further, the environmental impact of RL activities has barely been considered in holistic way in available literature. In this study, a system dynamics model has been developed to analyze and comprehend the green performance of RL activities by predicting the environmental impact of RL activities. The proposed model has been validated by a case study in the context of a food supply chain. In the company where the case study is carried out, the environmental effects of RL activities have been analyzed. These activities in a food supply chain in terms of CO2 (carbon dioxide), NOx (nitrogen oxide), SO2 (sulfur dioxide), and PM (particulate matter) emissions have been predicted through a system dynamics model for the years 2020 to 2024. The proposed methodology is applied in a food supply context, a major player in retail business, especially in emerging economies. According to our findings, the RL activities in a food supply chain can significantly contribute to green performance management by minimizing food waste and loss; hence, the environmental impacts of such activities should be closely examined from a managerial perspective.

“…In another study, Turkey's renewable and yearly energy potential of biomass was estimated at respectively 17.2 and 32.6 Mtoe [31]. In 2018, in a study Turkey's biogas potential of cattle manure 107.8 PJ/year, biogas potential of chicken manure 36.5 PJ/year, while the biogas potential of agricultural waste 305.3 PJ/year that was reported [32]. Here, it is emphasized that Turkey is a significant amount of energy by plants in addition to animal manure.…”

ÖzToday, energy demand has become one of the important problems. The rapid growth of the world population and the development of the industry have increased the need for energy. The vast majority of the world's energy needs come from natural energy sources. But the limited availability of these energy sources has led people to search for renewable energy sources. One of these renewable energy sources is biogas energy. Biogas is a gas mixture of organic substances formed by anaerobic microorganisms under anaerobic conditions at certain temperature conditions. It is flammable due to the presence of methane (CH4) gas in average 65% by volume in the biogas. Other gases outside the methane in the biogas are undesirable gases. Biogas purified from unwanted gasses is the natural gas used today. Biogas production gains importance in terms of disposal of organic materials. Black Sea Region in our country, due to the disadvantage of the geographical location and the lack of settlements has been very difficult to store the landfill. Biogas production in the Black Sea Region is gaining importance in terms of eliminating these wastes and obtaining energy. In this study, biogas potential of kitchen wastes of provinces in Black Sea Region was determined. The highest biogas potential of the Black Sea Region was found to be 51 163.20 m 3 / day in Samsun province. The biogas potential of the kitchen wastes in the Black Sea Region was 296 015.18 m 3 /day. Günümüzde enerji ihtiyacı önemli problemlerden biri haline gelmiştir. Dünya nüfusunun hızlı artışı ve sanayinin gelişmesi enerji ihtiyacını artırmıştır. Dünya enerji ihtiyacının büyük çoğunluğu doğal enerji kaynaklarından sağlamaktadır. Fakat bu enerji kaynaklarının sınırlı olması insanları yenilenebilir enerji kaynakları arayışı içerisine sokmuştur. Bu yenilenebilir enerji kaynaklarından biri de biyogaz enerjisidir. Biyogaz, organik maddelerin oksijensiz ortamda belirli sıcaklık şartlarında, anaerobik mikroorganizmalar sayesinde oluşan bir gaz karışımıdır. Biyogaz içerisinde hacimsel olarak ortalama %65 oranında metan (CH4) gazı bulunmasından dolayı yanıcıdır. Biyogazın içeriğindeki metan dışındaki diğer gazlar istenmeyen gazlardır. İstenmeyen gazlardan arıtılmış biyogaz günümüzde kullanılan doğal gazın yerini tutmaktadır. Biyogaz üretimi organik maddelerin bertaraf edilmesi açısından önem kazanmaktadır. Ülkemizde Karadeniz Bölgesi, coğrafi konumunun oluşturduğu dezavantajı ve yerleşim yerlerinin az olması nedeniyle mutfak çöplerini depolamak çok zor hale gelmiştir. Karadeniz Bölgesinde biyogaz üretimi bu mutfak atıklarının giderilmesi ve enerji elde edilmesi açısından önem kazanmaktadır. Bu çalışmada Karadeniz Bölgesindeki illerin mutfak atıklarından oluşabilecek biyogaz potansiyeli belirlenmiştir. Karadeniz Bölgesinin en fazla biyogaz potansiyeli 51 163.20 m 3 /gün olarak Samsun iline ait olduğu bulunmuştur. Karadeniz Bölgesinin mutfak atıklarından üretilebilecek biyogaz potansiyeli ise 296 015.18 m 3 /gün olarak bulunmuştur.

“…In review of other countries of the Middle East, Turkey, generates approximately 26 million tons of waste per year, according to the statistical basis of the country, of this total, 20 million correspond to biodegradable waste, which generates a strong environmental, economic problem in parallel with the growth of its population, these disadvantages are greater in the large cities of the country. Although it is true, if there are management programs, however, in practice, there is no control and cooperation between the institutions designed to take care of the environment, responsible for technical and financial management (Salihoglu et al, 2018).…”
