“…Therefore, the policymakers of these nations have to redesign the energy and trade policies in order to safeguard the environment and ensure sustainable economic development. Over the years, the researchers have been advocating about the positive impact of alternate energy sources on environmental quality (Mizsey and Racz, 2010;Ingrao et al, 2016;Schober et al, 2018;Hassan et al, 2019). As these nations are still at emerging phase, therefore implementation of high-end renewable energy solutions might prove to be harmful for economic growth.…”

This study examines the association between foreign direct investment (FDI) and carbon emissions for the Middle East and North African (MENA) region in 1990-2015, including biomass energy consumption as an additional determinant of carbon emissions. We apply the generalized method of moments (GMM) to validate the existence of the pollution haven hypothesis (PHH). The N-shaped association is also validated between FDI and carbon emissions. The link between economic growth and carbon emissions is inverted-U and N-shaped; that is, it satisfies the environmental Kuznets curve (EKC) hypotheses. Biomass energy use lowers carbon emissions, and the causality analysis reveals that FDI causes CO2 emissions. Clearly, the results confirm the existence of a feedback effect between economic growth and carbon emissions. The connection between biomass energy use and CO2 emissions is also bidirectional. The empirical findings suggest policy makers to design comprehensive trade and energy policies by targeting the cleaner production practices, for not only to ensure environmental sustainability, but also to fulfil the objectives of sustainable development goals.

“…The selection of precursors available for use in alkali-activation has also broadened significantly in recent years, with particular emphasis being placed upon the use of materials for which there is not strong competition in demand from utilization in blends with Portland cement. For example, calcined non-kaolinitic clays [17][18][19][20], palm oil fuel ash [21,22] or other minerals [23][24][25][26], have been shown to yield alkali-activated binder systems with technical properties that are attractive in given applications. Various industrial by-products or wastes without current large-scale utilization as supplementary cementitious materials have been tested and validated for use in alkali-activated binders, including red mud [27][28][29] and various glassy wastes including slags, some of which can benefit from thermal re-processing or modification to improve their reactivity before use [10,[30][31][32][33][34][35].…”

The development of low-carbon binders has been recognized as a means of reducing the carbon footprint of the Portland cement industry, in response to growing global concerns over CO2 emissions from the construction sector. This paper reviews recent progress in the three most attractive low-carbon binders: alkali-activated, carbonate, and belite-ye'elimite-based binders. Alkali-activated binders/materials were reviewed at the past two ICCC congresses, so this paper focuses on some key developments of alkali-activated binders/materials since the last keynote paper was published in 2015. Recent progress on carbonate and belite-ye'elimite-based binders are also reviewed and discussed, as they are attracting more and more attention as essential alternative low-carbon cementitious materials. These classes of binders have a clear role to play in providing a sustainable future for global construction, as part of the available toolkit of cements.

“…The utilisation of wood fly ash as a cement replacement material in construction industry can be an excellent environmental choice. Cement production is one of the main man activities that generate high amounts of CO 2 emissions, where each tonne of cement produced generates about 950 kg of CO 2 (Israde-alc, 2019;Shi et al, 2011). Therefore, wood fly ash utilisation on this industry save costs for ash disposal (Fuller et al, 2018;Lisbeth et al, 2016), decrease energy requirement (for cement clinker production) and decrease greenhouse gas emission (by cement clinker substitution) (Ukrainczyk et al, 2016).…”

Wood fly ash (WFA) is a waste material produced in power plants as result of forest residues combustion to produce power and heat. In countries like Portugal, this waste is disposed of in landfills. Since this material shows pozzolanic characteristics, several studies have been done to evaluate its use as a construction material. This work shows an overview of some published results about the effect of the utilisation of WFA, as a supplementary cementitious material, on the durability and quality of concrete. The results showed that the increase on the wood fly ash content leads to a negative effect on the concrete properties when compared with a conventional concrete. However, the results showed that the behaviour of wood fly ash concrete is very similar to the coal fly ash concrete, which is the most pozzolanic material used in the world. In terms of durability, it was verified that WFA improved the most of the durability characteristics with the exception of carbonation resistance. However, more experimental analysis needs to be developed in terms of wood fly ash concrete durability. Results suggested that using wood fly ash to replace cement is a valuable sustainable option for concrete production. This manuscript discusses the key factors and attempts to provide new information about the application of the wood fly ash on concrete.
