چکیده
Bioenergy with carbon capture and storage (BECCS) is a dioxide removal (CDR) solution necessary to achieve net-zero-carbon-emissions goals. While the BECCS potential from large industrial emitters has been quantified, of small emitters, such as biogas facilities, not investigated. Moreover, most solutions rely on expected availability geological capacity for future CDR implementation, although deployment CO2 transport supply chains still barrier ambitions. An alternative opportunity permanent sequestration concrete, in which captured can be permanently fixed through mineralization technologies. We describe discuss this by quantifying European bioenergy capture, utilization, (BECCUS) chain, relies biogenic facilities source, concrete sink. This available today, adopted seamlessly, does need economies scale its deployment. find that produce 24 Mtons per year, 4 year are emitted already upgrading into bio-methane. estimate recycled aggregates Europe could store up 8 year. Despite limited potential, BECCUS would reduce transportation distance system complexity compared chains, result marketable product, namely concrete. Overall, combines utilization sequestration, hence contributing carbon-neutrality

Performance of High-strength Concrete Made with Recycled Ceramic Aggregates
Recent scientific concerns to achieve sustainability in construction have suggested the implementation of using recycled aggregate in concrete because it has the potential to reduce the demand for extraction of natural raw materials and decrease the volume of wastes landfilled. In this respect, this study aims to investigate the suitability of using ceramic tile (CT) and ceramic sanitary (CS) w...
متن کاملLow Cycle Fatigue Behavior of Concrete with Recycled Concrete Aggregates
A comparison of concrete containing recycled concrete coarse aggregates and natural coarse aggregates subjected to high strain, low cycle compressive fatigue is presented. Using a strain based feedback control loop, concrete cylinders are compressed at 15µε/s to a specified strain then unloaded to zero stress for 10 cycles. After cycling, all samples are loaded to a strain of 0.008. Direct conc...
متن کاملCarbon dioxide sequestration in concrete in different curing environments
This paper summarizes the results of an investigation on carbon dioxide (CO2) sequestration in concrete. Concrete mixtures were not air entrained. Concrete mixtures were made containing Class C fly ash at 0%, 18%, and 35% of total cementitious materials. Effects of three different curing environments on properties of concrete were studied: (1) moist-curing room with 100% relative humidity (RH) ...
متن کاملCan increasing carbon dioxide cause climate change?
The realistic physical functioning of the greenhouse effect is reviewed, and the role of dynamic transport and water vapor is identified. Model errors and uncertainties are quantitatively compared with the forcing due to doubling CO2, and they are shown to be too large for reliable model evaluations of climate sensitivities. The possibility of directly measuring climate sensitivity is reviewed....
