ÖZNüfus artışı, tarım alanlarının yetersizliği ve iklim değişiklikleri gibi sorunlar nedeniyle, gıda kaynaklarının sürdürülebilirliği giderek önem kazanmaktadır. Gelecekte özellikle protein gereksiniminin karşılanması temel bir sorun olarak öngörülmektedir. Yenilebilir böcekler geleneksel protein kaynakları ile kıyaslandığında üretimlerindeki avantajlar nedeniyle sürdürülebilir gıda kaynakları olarak değerlendirilmektedir. Güney Amerika ülkeleri ve Çin gibi ülkelerde geleneksel olarak tüketilen ancak batı toplumlarında neofobi ve tiksinme nedeniyle kabul görmezken bütün formu yerine un formunda kullanılması entomofajiyi uygulamak için umut verici bir seçenek olarak görülmektedir. Yenilebilir böceklerin, besleyici özellikleri ile antidiyabetik ve antimikrobiyel gibi potansiyel etkileriyle sağlık üzerine faydalarının incelendiği çalışmalar artmaktayken toksik ve alerjik etkileri üzerine çalışmalar halen yetersizdir. Yenilebilir böceklerin, özellikle Avrupa Gıda Güvenliği Kurumu'nun (European Food and Safety Authority, EFSA) 2021 yılı başında yayınladığı sarı un kurdunun gıda olarak tüketilmesini onaylayan yönetmelik ile yenilebilir böceklerin bilim dünyasında daha fazla konu olacağı düşünülmektedir.
Development of the automotive industry not only facilitated our daily lives, but also introduced environmental stress. The automotive industry consists of both the original equipment manufacturers (OEMs), and a great variety of suppliers that support this industry. Most of the published studies focus on the environmental impacts of the OEMs; the impacts of suppliers were generally neglected. The objective of this study was to evaluate the types and amounts of solid and hazardous wastes generated by the automotive industry especially in relation to the supplier companies supporting the automotive manufacturers in Turkey. A survey was conducted with representative numbers of automotive manufacturers and suppliers located in Bursa, Turkey to obtain data on resource usage, waste types, and waste amounts generated. One hundred and five different parts of an automobile were examined in the framework of the study. Interviews were also conducted with the suppliers about the details on each item produced. Resource usage, solid and hazardous waste generation during the production of each component of an automobile were calculated. The environmental burden of the automotive industry in Turkey was roughly calculated in terms of waste generation and resource usage based on energy and water. It was seen that of the items constituting an automobile, which are provided by the suppliers, 47% is made of plastics, 31% is made of textile, and 21% is made of metals. The amounts of water and electricity used for all the items by the suppliers were found as 0.60 m 3 /vehicle and 190 kWh/vehicle, respectively. Water and electricity usage by OEMs were 3.47 m 3 /vehicle and 1763 kWh/vehicle, respectively. Solid and hazardous waste generated by OEMs were found as 48.97 kg/vehicle and 7.04 kg/vehicle, respectively, and by suppliers were 5.71 kg/vehicle and 0.6 kg/vehicle, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
