Carbon dioxide (CO2) capture using CaO-based adsorbents has recently attracted intense attention from both academic and industrial sectors in the last decade due to the high theoretical capacity of CO2 capture, low cost, and potential use in large scale. However, the successful development of CaO-based adsorbents is limited by significant sintering of adsorbent particles over a number of cycles of CaO carbonation/calcination. In this work, a systematic understanding of fundamental aspects of the cyclic carbonation/calcination of CaO-based materials is reviewed.

There are increasing policy and market drivers for removing chemicals of concern from manufacturing processes and products. These drivers have centered primarily on developed countries. However, global activities through the United Nations, individual countries, and advocacy organizations are increasing concerns about chemical impacts in developing countries and economies in transition as well. While reducing the use of chemicals of concern is a primary goal, eliminating such substances without thoughtful consideration for their replacements can lead to regrettable substitutions.
To fight against the biodiversity loss and to take advantage of ecosystem services that nature can offer, urban planners integrate green spaces in urban projects. However to assess green spaces, attention is generally paid to local biodiversity (i.e. “in situ”)which concerns the plot on which buildings are constructed. The biodiversity impacted outside the construction site (i.e. “ex situ”)which concerns the extraction of materials, transportation and waste, is rarely associated to the project assessment.
The UN 17 Sustainable Development Goals (SDGs) and the 169 targets have been considered in multidisciplinary approaches worldwide. Whereas, several environmental, economic and social development concerns have been covered by the UN 2030 Agenda. The aim of this research is to investigate the complexity of the interactions between building materials and the SDGs, in an attempt to establish a knowledge-based decision support system for policy-makers, designers and construction stakeholders regarding the implementation of 2030 agenda.
This book chapter addresses goals 3, 13 and 15 by discussing the coronavirus family (Coronaviridae) as a species specificity and interspecies transmission.
This book chapter addresses goals 14, 15, and 12 by exploring the origins of microplastics (relating to our society, production and consumption) and the diverse and harmful impacts of microplastics in the marine environment on life underwater, as well as interactions with humans and other life on land at the end of the cycle.
Rising demand for renewable resources has increased silage maize (Zea mays L.)production characterized by intensive soil management, high fertilizer and pesticide inputs as well as simplified crop rotations. Advantages of renewable biomass production may thus be cancelled out by adverse environmental effects. Perennial crops, like cup plant (Silphium perfoliatum L.), are said to benefit arthropods. Substituting silage maize could hence increase biodiversity and foster ecosystem services.
Based on literature and six country studies (Belgium, Denmark, Finland, Netherlands, Sweden, Slovakia) this paper discusses the compatibility of the EU 2020 targets for renewable energy with conservation of biodiversity.We conclude that increased demand for biomass for bioenergy purposes may lead to a continued conversion of valuable habitats into productive lands and to intensification, which both have negative effects on biodiversity.
Wood residues from forest harvesting or disturbance wood from wildfire and insect outbreaks may be viewed as biomass "feedstocks" for bioenergy production, to help reduce our dependence on fossil fuels. Biomass removals of woody debris may have potential impacts on forest biodiversity and ecosystem function. Forest-floor small mammals, such as the southern red-backed vole (Myodes gapperi) that typically disappear after clearcut harvesting, may serve as ecological indicators of significant change in forest structure and function.
This literature review identifies the impacts of different renewable energy pathways on ecosystems and biodiversity, and the implications of these impacts for transitioning to a Green Economy. While the higher penetration of renewable energy is currently the backbone of Green Economy efforts, an emerging body of literature demonstrates that the renewable energy sector can affect ecosystems and biodiversity.
