“…They also found that a better biogas yield was produced by using the SSAD method compared with liquid anaerobic digestion (LAD). Haryanto et al [72] investigated the effect of urea addition on the biogas yield from co-digestion of rice straw and cow dung using a semi-continuous anaerobic digester, and concluded that urea addition positively influenced the biogas yield and its quality.…”

Fossil fuel depletion, along with its ever-increasing price and detrimental impact on the environment, has urged researchers to look for alternative renewable energy. Of all the options available, biomass presents a very reliable source due to its never-ending supply. As research on various biomasses has grown in recent years, waste from these biomasses has also increased, and it is now time to shift the focus to utilizing these wastes for energy. The current waste management system mainly focuses on open burning and soil incorporation as it is cost-effective; however, these affect the environment. There must be an alternative way, such as to use it for power generation. Rice straw and rice husk are examples of such potential biomass waste. Rice is the main food source for the world, mostly in Asian regions, as most people consume rice daily. This paper reviews factors that impact the implementation of rice-straw-based power plants. Ash content and moisture content are important properties that govern combustion, and these vary with location. Logistical improvements are required to reduce the transport cost of rice husk and rice straw, which is higher than the transportation cost of coal.

It is essential to valorize waste biomass and promote a circular economy for realizing sustainability and decarbonization goals. In this review, we specifically focus on anaerobic digestion (AD) intensified via hydrodynamic cavitation (HC) and modeling as an effective biomass valorization strategy. AD is known to generate renewable energy (biogas) and fertilizer (digestate) and is therefore aligned with the circular economy framework and has the potential to decarbonize the transportation, energy, and heat sectors, which contribute a major share to the current global carbon emissions. The AD-based pathway, though robust, has key challenges such as poor carbon conversion and subpar biogas yields coupled with long residence times. This is mainly due to the recalcitrance offered by the feedstock. HC-based biomass pretreatment is critically reviewed here as a promising AD intensification strategy to overcome this recalcitrance. HC devices and their key aspects of design and scale-up are discussed. Vortex-based HC devices were found to be superior to conventional linear flow HC devices in terms of pretreatment performance and ease of scale up. The use of reaction engineering models of AD for overall optimization of biomass valorization is also discussed. The need for developing an intermediate modeling approach between empirical models and complex biochemical pathway-based models is highlighted. Such an intermediate approach requires simple biomethane potential (BMP) measurements for obtaining essential model parameters. With such parameters obtained from BMP data, the model was found to be useful for simulating and optimizing performance of AD. A prospective AD-based biorefinery is briefly discussed with multiple allied valorization pathways. This review will be useful to researchers and practicing engineers for realizing effective valorization of waste biomass.

Straw is a waste produced from the threshing and harvesting of rice. So far, rice straw has only been removed. In fact, it can be used as a potential energy source. This paper aims to examine the potential of rice straw as a renewable energy source in Indonesia. Opportunities and challenges were evaluated based on extensive and in-depth literature review. The paper discussed rice straw potential, its characteristics and benefits of using straw energy. Technology to convert rice straw into energy was also discussed. Results showed that renewable energy potential of rice straw is 28.8 TJ/year. Conversion technologies that can be applied include densification, combustion, gasification, and biogas. The biggest challenge for using rice straw energy is collection and transportation. Densification may overcome density problem by producing high quality pellets or briquettes that reduce transportation and storage costs. Straw characteristics need to be improved to increase its combustion properties.
