Bagasse and rice hulls ash are both waste materials. In recent years, in order to meet environmental protection, these materials have been recycled in the production of porous ceramics. A solid-state reaction mechanism of calcined alumina and talc was used to prepare cordierite-spinel porous ceramics. Talc was added from 30 to 60 wt.% at the expense of alumina and sintered at 1400 • C for 2 h. The effect of bagasse and rice hulls ash (as a pore forming agent) on the densification parameters, cold crushing strength (CCS), and pore size distribution was also studied. The phase composition (X-ray diffraction) and microstructure (scanning electron microscopy) of sintered samples were investigated. The results showed that the main phases present in the samples are cordierite, corundum, spinel, and sapphirine. In the sample with a higher amount of talc additions (60 wt.%), only the formation of the cordierite and spinel phases was observed. The bulk density of the samples and the apparent porosity ranged from 1.77 to 2.26 g/cm 3 and from 28.6% to 48.21%, respectively. The CCS of the samples ranges from 13.9 to 36.3 MPa. The microstructures of the sintered samples were observed for the formation of cordierite phase, alumina phase, and spinel phase in an excellent crystallization and phase arrangement.

“…The implications of the presented research are relevant not only to researchers but also to entrepreneurs and policymakers dealing with sustainable rice intensification in Iran and other developing countries, especially those severely affected by climate change and the overexploitation of natural resources [27,59,60]. The research findings feed into the science-policy-practice dialogue to foster the diffusion of sustainable intensification, by supporting the creation of synergies between scientific evidence, the design of targeted policy instruments, and the conscious adoption of farming practices on the ground [61].…”

This article aims to show the potential contribution of high-yielding rice varieties to achieve sustainable intensification in paddy farming, by focusing on a developing country. A comparative life cycle assessment of traditional vs. high-yielding varieties is carried out by comparing the area-based and yield-based results. Primary data are collected through a farm survey (49 farms in the Mazandaran province, Iran; spring 2018). The results highlight that high-yielding varieties can reduce the yield-scaled impacts. However, area-scaled impacts are subject to increase for most impact categories. Statistically significant trade-offs involve global warming potential (+13% per ha and −28% per t in high-yielding varieties) and fossil resource depletion (+15% per ha and −26% per t in high-yielding varieties). Pesticide management is the most alarming practice. High-yielding varieties increase pesticide consumption and related toxicity impacts both per t and per ha. This study is a new contribution to the literature by improving and broadening the mainstream productivity perspective of current life cycle assessment research about crop varieties. The lessons learnt from this study suggest that the trade-offs between yield-scaled and area-scaled impacts should be carefully considered by decision-makers and policymakers, especially in developing countries that, like Iran, are affected by the overexploitation of natural resources. Targeted policy and the development of farmer education and advisory services are needed to create the enabling conditions for farm management changes, including conscious use of production inputs while avoiding heuristics.

“…Sugarcane is Brazil’s primary raw material used for ethanol production, mainly because it spreads in the country due to the favorable climate and soil, but also because it provides the highest energy efficiency for ethanol production . In addition, sugarcane bagasse can be used for the production of second-generation ethanol and is normally co-processed for the production of thermal and electrical energy …”

Sugarcane is currently the primary raw material for ethanol production in Brazil. However, in recent years, corn has become an exportable commodity in the country, and many projects have emerged for ethanol production from this feedstock. The assessment of the market demand for ethanol in Brazil in the coming years indicates a deficit in domestic production. Thus, strategic planning is essential to guide future industry investments and ensures competitiveness and development in this segment. In this work, process simulation is used to compare sugarcane and corn ethanol production technologies in terms of their material and energy demands, and to measure the potential impact of the corn entrance in the current Brazilian market. It was shown that ethanol from corn can have a cost 5% lower than 1G ethanol and 17% lower than 1G2G ethanol from sugarcane. If 50% of the additional demand for ethanol is supplied from corn, a potential reduction of up to 5% can be expected in the biofuel average price, depending on the corn price. One corn ethanol plant could supply almost the same amount of biofuel than two or three sugarcane ethanol plants, and adaption of existing mills to flex processing plants is indicated as a viable alternative.
