Selection For

As the high demand of energy of the developing countries is met by importing energy and different energy technology, it has become increasingly necessary to discuss the environmental impacts throughout the life cycle of those technologies and make better decisions. Developed in the late 1960s, Life Cycle Assessment (LCA) has become a wide-ranging tool used to determine impacts of products or systems over several environmental and resource issues. The LCA approach has become more prevalent in research, industry and policy with growing concern for the environment. Therefore, the aim of this paper is to introduce the use of LCA in the decision-making process while selecting an energy technology. In this way, more environmentally conscious decisions will be made as LCAs can provide a better basis for this process.

Efficient Delivery

The rationale for this publication emanated from the challenges facing the efficient delivery of construction projects in developing countries. Although, some aspects of the book focus on key applications in Cameroon, a holistic approach was adopted where an overview of challenges related to construction for developing countries was considered. To re-focus issues addressed in this book, this last Chapter provides a summary of what has been covered in each Chapter. Also, major achievements and challenges will be discussed. Nevertheless a construction matter can not be seriously handled today without taking into account environmental issues. For this reason, we will say just a few words about environment. Indeed, wherever infrastructures in general and buildings in particular through production and emission of toxic matters and gas have harmful consequences on the environment. They must be assessed and monitored to reduce the risk of pollution. Among many environmental assessment methods, life cycle assessment (LCA) seems to be the most suitable. Wherever, it involves a lot of data and must be handling with a lot of caution. The life cycle assessment tools used in developed countries is not suitable in developing countries context. It should be benefit for them to develop a simple and suitable methodology easy to manage, in order to propose an environmental impacts measurement of construction projects' and buildings. The High Environmental Quality, which a priori ensures minimized environmental impact and promotes the principles of sustainable development, is the solution that seems best suited for the design of many social infrastructures projected in developing countries. This is going to be for them the future challenge for the next decades.

The Status

PurposeLife cycle assessment (LCA) has considerably contributed to increasing the environmental friendliness of buildings in developed countries. However, it is hard to find evidence on the application of LCA for buildings in developing countries; particularly, Sri Lanka. There is a lack of research to compare the status of LCA of buildings in developed countries vs developing countries. In this context, the purpose of this study aims to examine the status of LCA implementation for buildings between developed countries and Sri Lanka, a developing country.Design/methodology/approachThe exploratory research was adapted, and in-depth interviews were held with LCA professionals from Sri Lanka and developed countries, respectively.FindingsRelatively less attention has been paid to the implementation of LCA for buildings in Sri Lanka compared to the developed countries due to the time and effort required to collect life cycle inventory data and limited stakeholder understanding of the LCA. Hence, this study proposed improvements, including the development of LCA databases containing region-specific data and conducting programmes to raise stakeholders' awareness to address the gaps in Sri Lanka.Research limitations/implicationsThe identified LCA implementation process for buildings could be used as a guide for first-time LCA users, and it equally makes a valued reference for experienced practitioners.Originality/valueA limited number of the studies formulate a comparison between the LCA for building in developed countries and developing countries. This research attempts to address this knowledge gap.

Introdução: A quantidade de Resíduos Sólidos Urbanos (RSU) tem aumentado consideravelmente ao longo dos anos, isto é consequência direta de vários fatores, entre eles o crescimento populacional da humanidade. A preocupação com o meio ambiente tem ganhado destaque na sociedade, pois a mentalidade de sustentabilidade tem desencadeado uma série de possibilidades para avanços científicos e tecnológicos no sentido da preservação ambiental. Objetivo: Realizar uma revisão sistemática para identificar estratégias para inserção de biogás proveniente da matéria orgânica dos RSU como solução energética. A hipótese é que esse biogás garanta o tratamento adequado de RSU, com benefícios ambientais. Material e Métodos: Revisão sistemática feita na base de dados SCOPUS, limitando as pesquisas para artigos publicados em periódicos e revisões. Os descritores utilizados nas buscas foram: urban solid residues, sanitary landfill, biogas, cogeneration, thermodynamics, life cycle assessment. Foram utilizados seus sinônimos correspondentes, assim como os operadores booleanos AND e OR. Resultados: A estratégia de busca elaborada forneceu um total de 157 estudos. Após a triagem pela leitura dos títulos e resumos, 45 estudos foram considerados potencialmente elegíveis e lidos na íntegra. Ao término das análises, 17 artigos preencheram todos os critérios de inclusão para o estudo, sendo publicados entre os anos de 2012 e 2021. A revisão sistemática da literatura demonstrou as vantagens da utilização do biogás para fins energéticos, confirmando também a redução de impactos ambientais. Os principais tratamentos utilizados nos estudos identificados foram de origem bioquímica (e.g., digestão anaeróbia) e termoquímica (e.g., incineração). Conclusão: Identificaram-se estratégias para inserção do biogás como fonte energética, demonstrando sua viabilidade e aplicabilidade no suporte à redução de emissões e atendimento de demandas energéticas. Observou-se a importância de propostas por novas alternativas para reaproveitamento de RSU, sendo uma problemática de extrema significância. Experiências de sucesso no mundo podem ser estendidas e adaptadas para o Brasil, principalmente no momento atual de reduzida geração hidrelétrica (e consequente bandeira vermelha na fatura elétrica), com benefícios para o governo e para a população. O aproveitamento energético do biogás traz vantagens econômicas e ambientais, reduzindo a sobrecarga das concessionárias de energia elétrica.
