This study presents an innovative life cycle assessment (LCA)-centric approach for optimizing the mix design of alkali-activated materials (AAMs) as sustainable alternatives to ordinary portland cement (OPC). The AAMs are developed using electric arc furnace slag (EAFS) and fly ash as precursors. The environmental performance is evaluated using the...

Bread waste (BW) is a common food waste in Europe and North America and has enormous potential as a biorefinery substrate for the sustainable synthesis of various platform chemicals. Our previous work made use of BW for the fermentative production of 2,3–butanediol (BDO). The present work evaluated the economic prospects and environmental consequen...
Chapter
Currently fossil-derived fuel is the major input driving the transportation sector. The primary environmental concern associated with this fossil dependency relates to greenhouse gas emission leading to climate change in addition to rapid depletion of natural reserves of petroleum and diesel. An alternative approach to reduce the environmental burd...
Chapter
The energy and transportation sectors are majorly dependent on fossil fuels to meet its ever-growing demand. Hydrogen, a non-carbon-based fuel is a suitable alternative as it eliminates the carbon emissions linked to fuel combustion. However, currently hydrogen is primarily produced from natural gas, coal, electrolysis, heavy oil, and naphtha. A sh...
Chapter
The efficacy of wastewater treatment technologies is primarily evaluated based on their ability to remove the desired contaminants. Once, the performance parameters are established, attention is paid to the economic feasibility of the field scale application of the technology. However, in the present era of awareness, a third evaluation criteria al...

Microbial production of 2,3-butanediol (BDO) has received considerable attention as a promising alternate to fossil-derived BDO. In our previous work, BDO concentration >100 g/L was accumulated using brewer’s spent grain (BSG) via microbial routes which was followed by techno-economic analysis of the bioprocess. In the present work, a life cycle as...
Article
The COVID-19 pandemic led to an increase in plastic used for medical purposes such as personal protective equipment and packaging materials. A very low share of plastics is recycled while the majority is sent to landfills. This plastic may degrade over time to form microplastics which may pollute land, air, and water sources. An increase in micropl...

In the present study, yard waste was pretreated by thermo-chemo-sonic pretreatment prior to anaerobic digestion to improve its anaerobic biodegradability. First, the pretreatment conditions were optimized using Box–Behnken design based response surface methodology for the maximum organic matter solubilisation. Then, the possible mechanism of delign...

In order to identify the most environmental-friendly pretreatment for pyrolsis of wood residue to levoglucosan (LG), for the first time a comparative life cycle assessment (LCA) was carried out for hot water treatment (HWT), torrefaction, acid pretreatment (AP) and salt pretreatment (SP) pathways. Since LG production can facilitate both resource re...
Chapter
Since the change in perspective of waste as an unutilized resource, the focus has shifted from waste reduction to waste utilization. Microbial fuel cell (MFC) has been a pioneer in this regard due to its unique ability to directly convert organic matter present in waste to electricity. Despite the tremendous improvement in power generated from lab-...
Chapter
The urban wastewater sector is primarily dominated by centralized wastewater treatment schemes equipped with an intricate network of sewers and pipes which cumulatively treats all the contaminants. The evolution of modular systems is expected to bring transition from conventional wastewater treatment scenarios for specific non transient water syste...

Electrochemical pretreatment is considered a promising technique to reduce recalcitrance nature of lignocellulosic biomass. Yet, a comprehensive knowledge on the performance of alkaline reagents in electrochemical pretreatment and the associated environmental impacts are at an early stage. The present study investigated and compared the effect of e...
Article
Anaerobic digestion (AD) under psychrophilic temperature has only recently garnered deserved attention. In major parts of Europe, USA, Canada and Australia, climatic conditions are more suited for psychrophilic (<20 ℃) rather than mesophilic (35 – 37 ℃) and thermophilic (55 – 60 ℃) AD. Low temperature has adverse effects on important cellular proce...

Production of valuable chemicals and fuels using bioelectrochemical systems (BESs) from low-valued solids, liquid, and gaseous wastes has gained enormous attention among scientific communities. For example, a microbial fuel cell can produce bioelectricity using wastewater as substrate in anode and oxygen as oxidant in cathode. Partial desalination...

In construction industry, apart from cement, the aggregate type, mix design method and transport distance of raw materials also contribute significantly to the environment related issues. This paper compares environment impacts of recycled coarse aggregate (RCA) and Particle Packing Method (PPM) of mix design approach with the concrete proportioned...
Article
Waste generation from healthcare facilities now has become a concerning issue as it contains plastic and metals. Medicine wrappers are one of the major portion of healthcare solid waste, which impel intensive solid waste management practice due to less possibilities of deriving by-products. However, it can be recycled and used as electrode material...
