In a scientific oration at IPB University, Professor Edy Hartulistiyoso introduced the concept of a Combined Heat, Power, and Product (CHPP) system designed to capture and repurpose industrial waste heat. The framework aims to integrate industrial efficiency with renewable energy generation by converting thermal losses into electricity and co-products. By applying thermochemical technologies, the system utilizes residual thermal energy to drive power generation while simultaneously processing biomassBiomass is a complex biological organic or non-organic solid product derived from living or recently living organism and available naturally. Various types of wastes such as animal manure, waste paper, sludge and many industrial wastes are also treated as biomass because like natural biomass these More into high-value secondary commodities.
The primary challenge addressed by this framework is the significant underutilization of industrial waste heat amid escalating national energy demands and intensifying emissions reductions targets. In Indonesia, industrial thermal energy systems rely heavily on conventional fossil fuels like coal and natural gas, despite substantial domestic renewable energy potential. This operational model leads to large amounts of thermal energy being expelled directly into the atmosphere, which lowers baseline industrial efficiency and exacerbates global greenhouse gas accumulation.
To mitigate these losses, the proposed CHPP system implements a multi-stage recovery mechanism that pairs an Organic Rankine Cycle (ORC) with specialized biomass pyrolysisPyrolysis is a thermochemical process that converts waste biomass into bio-char, bio-oil, and pyro-gas. It offers significant advantages in waste valorization, turning low-value materials into economically valuable resources. Its versatility allows for tailored products based on operational conditions, presenting itself as a cost-effective and efficient More. The ORC technology captures low-temperature industrial waste heat and converts it into supplementary electricity to support regional grid networks or localized operations. Simultaneously, the higher-temperature fractions of the residual heat stream supply the thermal energy required for the pyrolysis of agromaritime biomass, eliminating the need for independent fossil fuel combustion during processing.
The implementation of the CHPP configuration yields measurable improvements in resource conservation and decarbonization. The process successfully converts underutilized agricultural and fisheries biomass residues into stable biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More and bio-oil, establishing a domestic source of value-added commodities. Furthermore, integrating these thermal systems assists industrial facilities in aligning with national mandates targeting a 51 percent renewable energy utilization rate and a 37 percent increase in overall energy efficiency.
