“…Shabbir et al (2016) [18] cited the example of rice husk as a biomass fuel that supports sustainability while also being cost-efficient for rural electrification as part of their study on CHP application in paper mills. Other examples include sugarcane bagasse for sugar mills (Mane, 2016) [19]; (Birru et al, 2018) [12], cassava waste from cassava starch plants (Yin et al, 2019) [20], or sugarcane straw (Watanabe et al, 2020) [21]. Biomass fuels also provide the added benefit of reducing net carbon emissions (Atkins et al, 2017) [22].…”

Malaysia’s energy intensity (GWh/GDP) shows an increasing trend since the 1990s, leading to the government’s efforts to promote energy efficiency via policies such as the National Energy Efficiency Action Plan (NEEAP), which includes the Energy Performance Contracting (EPC) initiative. This paper reviews recent publications in industrial Combined Heat and Power (CHP) with a focus on international case studies relevant to Malaysian industries that use industrial steam and highlights trends within the research area. It also provides the basis for more case studies to be performed in the Malaysian industry to improve energy efficiency while also supporting further academic research in the area. Additionally, the paper documents the importance of data collection and analysis as well as demand forecasting, not only for a better understanding of industrial energy systems but also to increase profitability since system loads may vary throughout a typical year. A multi-criteria and comprehensive approach is recommended in future case studies to ensure energy efficiency, economic returns and environmental impact are considered to ensure long-term sustainability. A summary of barriers to CHP implementation in the industry is also included to provide a broad understanding of industrial CHP.

“…Cassava is one of the main raw materials for starch production which is widely grown in African and Asian countries. Except the cost of raw cassava, the energy accounts for a significant proportion in their starch production cost, including electricity for powering factory machinery, and biogas or heavy fuel oil for starch drying (Wattanasilp et al, 2021;Yin et al, 2019). Starch production from cassava is a major industry and source of income in several tropical countries such as Thailand, Vietnam, Brazil and Colombia, with an average output of about 3-4 million tons per year (Lerdlattaporn et al, 2021;T.…”

Reducing energy consumption and green house gas emissions is a crucial issue in the cassava starch processing industry. In this study, the integrated system combining livestock, cassava cultivation and cassava production at the same area will lead to both zero emission goal and economic efficiency, a typical example of an effective agro-industrial symbiosis. A heat exchange/recovery system was applied including the economizer, the heat exchanger tank, the biogas tank, and the boiler. The economizer attached to the boiler’s chimney transfers heat from exhaust gases for pre-heating feed water entering boiler. The biogas tank recovers energy from the wastewaters of starch production and livestock farm, and the generated biogas was used as fuel for the boiler. Excess heat from the production was used for evaporating (removal of) NH3 in wastewater flow from the biogas tank, and for heating the biogas system in oder to enhance the efficiency of methane production. A biochar filter was attached to economizer for adsorption of released ammonium, and the biochar after adsorption was combined with sludge from the biogas tank to produce a solid biofertilizer. The energy and exergy efficiency, energy losses, and exergy destruction for heat recovery system were analyzed. The specific energy consumption (SEC) was used to evaluate the overall energy efficiency for cassava starch factory with a capacity of 200 tons/day. The results show that there is a high potential to recyle waste into energy in the cassava starch industry, and the total energy saving and reducing GHG emissions per year of the cassava starch factory were 5.4%/year and 278,773 tons CO2/year, respectively.

“…The conversion of solid waste into high quality bioproducts in the integrated cassava wastes biorefinery could enhance the economic efficiency as well as reducing the environmental burden [22]. The sollutions for closing the loop materialswaterwatesenergyfoods in the cassava production sector have proven high efficiency when comparing with the traditional production methods with reducing 90% of global warming [23,24]. Moreover, the recycling of cassava production wastes into qualified products in packaging production under circular economy is also an effective and promising strategy for climate change mitigation [25].…”

Cassava starch production is a key industrial production of Tay Ninh province, Vietnam. However, this production chain has also caused many negative impacts on the environment. This study applied the principles of circular economy to analyze the waste streams via linear programming method for cassava starch circular production chain towards zero waste emission. The results show that the cassava starch indutry can achieve the goals of zero electricity, zero waste, and zero fossil energy by re-planning the production chain. The chain’s output products are 517.5 tons of bio-oil/year, 206.7 thousand tons of biochar/year, 190.0 thousand tons of dry pulp/year, 10 million m<sup>3</sup>/year of liquid fertilizer. In order to increase further the value of the chain in the circular economy, future research needs to study the feasibility of a solution to reuse wastewater to produce microalgae, as well as evaluate the effectiveness of these methods. The optimization method applied in this study can also be extended to similar agricultural chains properties such as rice processing, sugar cane, etc.
