Over the past 40 years, development of Ceramic Matrix Composites (CMCs) has focused mainly on improvement material performance and optimization cost-efficient production routes. Recently, more fields application have opened up for CMCs, in which environmental impacts are relevant. These barely been investigated so far but receive growing interest due to increasing awareness consequences. Our in...

Abstract One of the biggest energy consumers and CO2 emitters in world is steel sector. With growth infrastructure construction, output has risen year over year. Therefore, a life cycle assessment inputs outputs at each stage manufacturing process necessary to enable adoption management offer sustainable production consumption. The Life Cycle Assessment method employed this study assess environ...

This study focuses on the life cycle assessment (LCA) of an onshore wind farm in India. The is conducted 10 Vestas 1.65 MW turbines situated Karnataka state Following ISO 14044 standard, SimaPro LCA software used to model process. functional unit chosen as 1 MWh sent out electricity. results cycle-based emissions are compared with those coal power plant. global warming potential found be 11.3 g...

The construction industry consumes more raw materials and energy than any other economic activity generates the largest fraction of waste, known as demolition waste (CDW). This has significant environmental implications, most notably in South American countries such Colombia, where it is handled inappropriately. study evaluated management processes currently used for fractions generated Ibagué ...

Due to their properties, silver nanoparticles (AgNPs) are widely used in consumer products. The widespread use of these products leads the release such into environment, during manufacturing, use, and disposal stages. Currently there is a high margin uncertainty about impacts nano on environment human health. Therefore, different approaches including life cycle assessment (LCA) being evaluate e...

A cadeia de valor da madeira tem como fonte principal uma matéria-prima renovável, apesar disso ainda gera impactos ambientais decorrentes fabricação dos produtos e do manejo inadequado resíduos. O aproveitamento pode chegar a menos 50% ao longo seu ciclo vida. objetivo deste trabalho consistiu em avaliar os diferentes destinações resíduos MDF (Medium Density Fiberboard) gerados 11 indústrias p...

Berdasarkan survei Greenpeace International, perusahaan Fast Moving Consumer Goods (FMCG) adalah kekuatan dominan di balik model ekonomi sekali pakai yang mendorong krisis sampah plastik berasal dari konsumsi dan proses produksi dalam rantai pasok juga menghasilkan limbah industri. Limbah industri harus ditangani secara tepat agar tidak menimbulkan efek lanjutan sehingga diperlukan adanya konse...

O gerenciamento de resíduos sólidos urbanos compreende desde a atividade coleta até disposição final dos rejeitos. manejo é uma questão complexa em todo mundo devido aos hábitos consumo e processo intenso urbanização das comunidades países desenvolvimento, como o Brasil, um desafio ainda maior à pressão sobre os orçamentos municipais. objetivo desse estudo analisar impactos ambientais do ciclo ...
