“…Previous studies indicate that agriculture produces drastic damages to the ecosystem, such as the emission of GHG, water contamination, and food security (Hussain et al, 2014;Liao et al, 2018;Miller et al, 2019). Some strategies can mitigate the harmful environmental impact of rice plantations.…”

Due to the climate change and increased attention toward environmental management issues, the agri-food sector has been extensively relying on research, development, and innovation (RDi) to transform conventional agricultural production into a sustainable and eco-friendly industry. While the academic contribution of research has been relatively easily identified in the literature, the assessment of its societal impact remains underdeveloped. Accordingly, this study employs mixed-method evaluation approaches, mainly ASIRPA framework and Impact Oriented Monitoring (IOM) model to better understand and measure the multidimensional impacts of RDi in the agri-food sector in Spain. The objective of this analysis is to identify the impact of research on the society and the ecosystem. An in-depth case study analysis is conducted to examine the "best practices" program to promote sustainable techniques in the rice cultivation. Empirical findings suggest a standardized index to measure the economic, socio-territorial, health, political, capacity building, and environmental impacts, involving the stakeholder-network evaluation. The study highlights important implications for firm management decisions monitoring research uptake and policy design in the agri-food sector.

“…The portion of rice husk used for energy purposes is regularly used as fuel in boilers for energy production, and after burning, it generates a new waste: rice husk ash (RHA). RHA is considered a pozzolana due to its source of amorphous silica 4 ; which promotes the application of RHA in multiple destinations, such as production of concrete 5 – 7 , mortars 8 , 9 , soil remediation processes 10 , adsorption 11 ; constitution of geopolymers 12 , and effluent treatment 13 .…”

This study evaluates the use of rice husk ash (RHA)-eggshell lime (ESL) and RHA-commercial lime (CL) as alternative binders for clayey soil stabilization, as well as the performance of soil-binder mixtures under acidic attack. A central composite design was carried out to analyze the reactivity by batch tests with a sulfuric acid solution. Physical and mechanical behavior was evaluated by compaction test and unconfined compressive strength (UCS). Reactivity tests demonstrated better neutralization of contaminant acidity for mixtures with ESL. The highest compressive strength, reactivity and partial encapsulation of toxic elements are associated with application of 30% RHA and 6% ESL in the soil. A C–S–H gel is observed in poorly crystalline phases through the XRD pattern. The application of RHA-ESL in soils exposed to acidic attack has environmental feasibility. Analysis of RHA grinding processes combined with the mixture strength over time, and its application tests in impermeable barriers, in landfills, are recommended.

“…As a massive emitter of CO 2 in the world, the cement industry could, therefore, be responsible for up to 8% of global CO 2 emissions [ 8 , 9 ]. Moreover, the negative impacts of using cement in concrete are associated with abundant depletion of raw material sources, which contradicts the principles of a circular economy [ 10 , 11 , 12 , 13 ]. As pointed out in the reports of the International Energy Agency [ 14 ], in the interest of creating an energy-saving framework, the cement industry should attempt to use sustainable alternatives for fuels and resources.…”

Pilot Scale Production of Precast Concrete Elements with Wood Biomass Ash

et al. 2021

Downsizing fossil fuel dependence and greenhouse gas emissions is at the forefront of a sustainable future. The expansion of renewable energy while striving to minimize dependence on fossil fuels has led to biomass taking the lead among renewable energy sources, with wood having the broadest application. Along with the growing trend of using biomass as a renewable energy source, the combustion of wood biomass results in wood biomass ash (WBA), leading to compelling amounts of waste. In this study, the technical feasibility of fly WBA from different Croatian power plants was analyzed to evaluate its potential use in precast concrete drainage elements and curb units. By implementing a performance-based design, the influence of various factors in thermal processing of wood biomass was investigated, together with a detailed characterization of WBA in order to assess the feasibility of using WBA as a secondary raw material in a large-scale industrial batching plant. The compressive strength and durability properties (water absorption, permeability, and freeze–thaw resistance) of concrete mixtures with WBA as a replacement for 15 wt% cement were evaluated and compared with the precast concrete manufacturer’s technical requirements. The main concerns identified were compositional inconsistency of WBA, workability downturn, delay in initial reactivity rate, and increased water absorption. Concrete with WBA based on a circular design has been found to be a viable solution to cement depletion, stepping up from recycling to reuse of industrial waste.
