“…Biomass to energy is accomplished either through thermochemical (for e.g., pyrolysis, gasification) [7,8] and biochemical methods (for e.g., anaerobic digestion (AD), composting) [6]. The multifaceted applicability of biofuel production and derived digestate as biofertilizer and carbon neutrality in nature prefers AD over other methods [1,9] from the late 1800s [10,11].…”

“…The biochar yield was 32% and 39.8% for rice straw biochar (RS-BC) and bone char (WB-BC), respectively, (Table 1) at high pyrolysis temperature of 550 • C. As a matter of fact, it was reported that the increase in pyrolysis temperature from 300 • C to 600 • C could adversely influence the yield of rice straw biochar due to the thermal degradation of massive hydrocarbons [2]. Krzesinska and Majewska [25] showed that pyrolysis of bovine bones resulted in the 30% yield of bone char.…”

“…According to the report of economic survey, Pakistan is ranked second in good quality rice production in the world with 9.76 Mt rice residues, brings out a yield of more than 7 million tons and ranked 10th in the world with respect to the production rate [1]. Conventionally, the rice straw is burnt in the fields, which adversely influences the environmental quality and releases greenhouse gases such as CO, CO 2 , CH 4 and NO X into the atmosphere, causes the formation of smog affecting human health [2]. At the same time, millions of tons of chicken, mutton and beef bones are being produced annually.…”

The current study is aimed at deriving biochar (BC) from rice straw (RS-BC) and waste bones (WB-BC), being wasted without adequate return at the expense of environmental degradation. The RS and WB feedstocks were pyrolyzed at 550 oC, and the potential of derived biochar as a slow nutrient releasing soil amendment was examined during the growth of ridge gourd. Proximate analysis of the prepared biochars showed significant improvement in ash content and fixed carbon as compared to their raw biomasses. Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX) analysis of RS-BC and WB-BC displayed a diverse range of functional groups viz. derivatives of cellulose and hydroxylapatite (HA); macro and microporosity; multiple nutrients. Application of RS-BC and WB-BC in potted soil alone and as biochar composite (RS-BC+WB-BC) at 5, 10 and 15% (w/w) and chemical fertilizer (CF) resulted in a significant increase in soil pH, electrical conductivity (ECe), cation exchange capacity (CEC) and water holding capacity (WHC) in exchange for growth and yield of ridge gourd. However, there were insignificant differences in the growth of plants in response to RS-BC, WB-BC alone and CF with biochar composite at 15% amendment. For giving insignificantly different growth results than CF, the prepared biochar composite showed outstanding potential as an organic fertilizer applicable in agrarian soils to elevate soil properties and yield of agricultural commodities.

“…Rice straw is an important by-product of crops; with the enhancement of people’s awareness of using crop waste resources [ 3 , 4 , 5 ], more and more researchers are paying attention to the comprehensive utilization of rice straw resources. Methods of utilization are mainly focused on energy supply by incineration [ 6 ], landfill compost [ 7 ], livestock feed [ 8 ], etc. Comprehensive utilization of rice straw is beneficial for alleviating the energy storage problem, stabilizing agricultural ecological balance and solving the pollution problem [ 9 ].…”

Rice straw-derived cellulose (RSC) with purity of 92 wt.% was successfully extracted from rice straw by a novel and facile strategy, which integrated the C2H5OH/H2O autocatalytic process, dilute alkali treatment and H2O2 bleaching process. Influencing factors of the cellulose extraction were systematically examined, such as ethanol concentration, alkali concentration, H2O2 bleaching process and so on; the optimal extraction conditions of cellulose was determined. A series of rice straw-derived cellulose acetate (RSCA) with different degree of substitution (DS) were prepared by the acetylation reaction; the effects of Ac2O/cellulose ratio, reaction temperature and reaction time on the acetylation reaction were investigated. Results of FTIR and XRD analysis demonstrated that highly purified RSC and RSCA were prepared comparing with the commercial cellulose and cellulose acetate. Solubility analysis of RSCA with different DS indicated as-prepared RSCA with DS of 2.82 possessed the best solubleness, which was suitable for electrospinning. Moreover, the flexible RSCA fibrous membrane was easily fabricated by a facile electrospinning method. Our proposed method provided a strategy for realizing the high-value utilization of waste rice straw resource, as prepared RSC and RSCA can be used as chemical raw material, and electrospun RSCA fibrous membrane has various applications in medical materials, food packaging, water purification and so on.
