The Indo-Gangetic plain of northern India is known for prevalent rice farming. Due to the lack of a rice straw waste management system, a large volume of rice straw is burned in the field. Therefore, we add value to rice straw by converting it into activated biochar and utilizing it to remove toxic metals from natural water. In this work, single-st...

The conversion of rice straw to biochar through pyrolysis can produce a low-cost and efficient adsorbent that removes metal contaminants from the aqueous. Biochar was derived at various pyrolysis temperatures (300–500 °C) and analyzed the physicochemical properties. The physicochemical properties of biochar, including pH (8.23–10.25), surface area...

A solar air heater is a type of heat exchanger that converts solar energy into thermal energy through the use of an absorber plate. It is widely used to dry agriculture products, space heating, curing industrial products and dry construction components, wood seasoning, etc. However, one of the major disadvantages is the poor heat transfer coefficie...

In this study, the slow pyrolysis of Prosopis Juliflora was performed to determine the product yield distribution and its physiochemical properties, thermodynamic and sustainability performance of a process. Findings indicate that the increase in process temperature (300–600 °C) negatively impacted biochar yield while positively affected bio-oil an...

Sustainable rice straw management in Northern India is a significant issue for farmers. Pyrolysis is one of the suitable options to create value addition and contributes to the circular economy. In this work, the thermal decomposition of rice straw at three heating rates 5, 10, and 15 °C/min was studied to evaluate the kinetics parameters, includin...

Environment-friendly rice and wheat straw management in the Indian states of Punjab and Haryana have been a significant challenge. Farmers have adopted in-situ burning of crop residues as it is almost out of no pocket expense. However, this practice amounts to releasing 42.32 MT hazardous pollutants and GHGs into the atmosphere, which has an estima...

The burning of tonnes of paddy straw in the open field by the farmers in Punjab has resulted in air pollutant emissions causing serious environmental and health consequences. The paper presents a study on the utilization of the surplus paddy straw in Punjab for biochar production by pyrolysis. From the study, 7.60 MT of paddy straw are available in...

About 65.82% of total electricity generation in Bangladesh come from domestic natural gas. Natural gas reserves are expected to deplete and become commercially unviable by 2030 at the current consumption rate, threatening the nation's energy security. Authors in this study investigated surplus crop residues availability and their electricity genera...

The main objective of the present study is to turn the wheel from waste to wealth by sustainable rice straw management practices over field burning in India. For that, slow pyrolysis of rice straw was carried out in a fixed bed reactor. The result indicated an increase in process temperature (300–600 °C) led to the decreased biochar yield, while pH...

Rice straw management is a significant challenge in northern India. In-situ combustion of rice straw is a practice to clear the agricultural field. Therefore, an attempt was made to add value to rice straw by producing activated biochar and check its efficacy to adsorbed Zn+2 contaminants from the water. The influence of pH, contact time, initial m...

The depletion of fossil fuels and the harmful consequences of its utilisation has been the major factor contributing to the need for shift towards the use of renewable energy (Vidal-Amaro et al., 2015; Østergaard and Sperling, 2014). The exploitation of fossil fuels over the years for meeting the growing energy needs of mankind has however, left a...

Biochar derived from rice straw has potential application as a cheap adsorbent for removal of Cu(II) from aqueous solution.
