To conduct a more in-depth study on carbon emissions and influencing factors during the materialization stage of prefabricated buildings, this paper focused residential building in Beijing. The LCA method, combined with BIM technology, was utilized to establish process-based “LCA-BIM” emission statistical platform propose calculation method. were calculated. results revealed that production materials contributed highest proportion emissions, accounting for 85.73% total stage. Specifically, reinforcing steel concrete dominated overall from materials, 97.44% total. Through quantitative analysis process calculation, main identified. This adopts approach empirical literature review, establishing six basic hypotheses four aspects: material selection, energy consumption, storage, materials. A structural equation model used theoretically validate SPSS27.0 AMOS28 software employed data analysis. From perspective impact, selection had strongest impact followed by while storage smallest impact. direct impacts, consumption findings can provide theoretical reference national institutions businesses evaluation decision-making.

Global gas markets are changing as natural (NG) is replaced by biomethane. Biomethane produced upgrading biogas, which can have a molar concentration of methane to over 98%. This renewable energy has been injected into the pipeline networks NG, offers possibility increase its usage in industrial and residential applications. However, expectation biomethane proportion on NG grids could fluctuations composition NG–biomethane mixture amplitude frequency. In this context, injection existing network raises discussion about extent variations quality will occur what permissible limits should exist, combustion characteristics affect operation processes, with consequences for consumers, distributors producers. study describes analysis regard use equipment, mixed or not taking account indicators interchangeability provides necessary level be achieved maintained efficient equipment originally designed operate NG. real data collected 92 consecutive days 2022 provided two different companies Brazil were used study.

Hydrogen as an energy vector is going to play important role in the global mix. On other hand, wastewater management has become a worldwide concern, urban settlements have been considerably increasing for decades. Consequently, biodigestion produce biogas (rich methane) water treatment plants could be interesting starting point obtain valuable gas that can converted into hydrogen through steam reforming. The aim of this work was review main aspects concerning reforming from plants. For purpose, whole chain, production and purification, considered, paying attention challenges new technologies its optimization. Thus, wide range possibilities offered, direct use syngas high purification (mainly pressure swing adsorption or membrane reactors), presenting advantages disadvantages. In any case, catalysts seems essential, such sulfide coke deposition control should addressed. conclusion, applied reality, with serious implementation at industrial level, according techno-economic assessment.

Even though many wastewater treatment systems have been applied so far, there is still a need to develop methods, the implementation of which are technologically and economically justified. The aerobic granular sludge (AGS) method, has developed for several years, may represent an alternative traditional technologies. One barriers AGS deployment limited knowledge on determinants efficiency anaerobic digestion (AD) AGS, as little research devoted it. Therefore, aim present paper summarize current state subject, including review technological conditions, process performance, parameters that can impact AD, currently used pre-treatment methods. stabilization performance compared against conventional activated (CAS). also identifies avenues further practical implementations optimize determine whether AD viable in full-scale plants.

Aggrandize industrialization and urbanization have resulted in many issues, such as increased energy demand, a plethora of waste output, negative environmental consequences. As result, there is excessive exploitation over-usage fuels finite resources, which paving the path for exhaustion fuels. Extensive use these fossil-derived has caused serious threats to environment terms greenhouse gases emission leading breathing troubles other associated health hazards. In order mitigate harmful effects fuels, researchers are more focused towards production application bio-based like bioethanol, biodiesel, biohydrogen etc. These biofuels produced from crops edible/non-edible materials emit much lower pollution compared Even though effective alternatives, high operational costs with low volume major limitations this process, available technologies cannot handle. With increasing nanoparticles catalysts several sectors due its unique properties catalytic activity, surface ratio, mechanical properties, etc., been explored recently. The present review focuses on nanocatalysts various stages biofuel production, different types nanocatalyst used innovative era their merits demerits. supply biofuels, feedstock large, improved processing, we may be able significantly our reliance fossil discusses current updates, future possibilities, challenges help make country self-reliant field green energy.

Ecofuels and their feedstock come in three main product classes: electrofuels (e-Fuels), biofuels, non-biowaste-derived fuels. originate from non-fossil sources, derived circular raw materials such as non-food organic waste, renewable hydrogen, captured CO2 through a rapid process of carbon fixation. Proposed regulation drafts under discussion indicate that new fuels would need to reach substantial degree climate neutrality. The manufacture all ecofuels, however, requires energy input accomplish the conversion initial feedstock; neutrality claims stem use electric and/or biomasses production process, but fossil are still primary sources global (and EU’s) power, most biofuels consumed EU transport mix crop-based, with potential conflicts food land use. Furthermore, entirely neglecting GHG emissions generation is scientifically debatable, impact related emissions) embedded used build facilities small, not nil. paper reports ecofuel trends according above-mentioned originating technologies discusses issues development.
