“…Embedded impacts in encapsulant material was a dominant contributor to the CI of both encapsulated systems, accounting for 89.3% (55. 8 stems from two key factors: (i) packed bed systems maintained over 74.3% COD removal for 95% of the simulated samples while the COD removal of fluidized bed systems was subject to much higher uncertainty; and (ii) 55−65% of a packed bed reactor's volume is filled with beads (compared to 3−25% for a fluidized bed reactor) and, as a result, the change in HRT leads to greater changes in packed bed reactor size and the amount encapsulant material needed (the latter of which is the dominant contributor to its cost and impacts). Although pair-wise comparison showed a packed bed system always outperformed a fluidized bed system at rCOD under identical conditions, the significant sensitivity of LC and CI to HRT (𝐷 ∈ [0.87, 0.98], 𝑝 < 0.0001;…”

“…3,4 Moreover, the concentrated organics in industrial wastewater represent an untapped source of renewable energy that could be recovered through distributed treatment at the industry. 5 With the potential to convert waste organics into bioenergy [6][7][8] and/or high-value bioproducts (e.g., medium-chain fatty acids [9][10][11] ), anaerobic technologies have been developed and deployed as distributed alternatives to centralized aerobic treatment. 12 Due to the slower growth rate of anaerobic microorganisms, small-or medium-scale applications of anaerobic technologies require decoupling solids residence time from hydraulic retention time (HRT) using biomass retention and separation methods.…”

This study aims to support the prioritization of research and development (R&D) pathways of hydrogel-encapsulated anaerobic technology to treat high-strength organic industrial wastewaters, enabling decentralized energy recovery and treatment to reduce organic loading on centralized treatment facilities. To characterize the sustainability implications of early-stage design decisions and to delineate R&D targets, an encapsulated anaerobic process model was developed and coupled with design algorithms for integrated process simulation, techno-economic analysis (TEA), and life cycle assessment (LCA) under uncertainty. Across the design space, a single-stage configuration with passive biogas collection was found to have the greatest potential for financial viability and the lowest life cycle carbon emission. Through robust uncertainty and sensitivity analyses, hydraulic retention time (HRT) and encapsulant volume were identified as the most impactful design decisions for the levelized cost and carbon intensity of chemical oxygen demand (COD) removal. Encapsulant longevity, a technological parameter, was the dominant driver of system sustainability and thus a clear R&D priority. Ultimately, we found encapsulated anaerobic systems with optimized fluidized bed design have significant potential to provide affordable, carbon-negative, distributed COD removal from high strength organic wastewaters if encapsulant longevity can be maintained at 5 years or above.

The use fossil energy consumption in Indonesia is increasing along with population growth and industrial development. Fossil energy oil and coal can produce greenhouse gas emissions and environment pollution. The largest producer of CO2 emissions comes from exhaust gases in the production process and motor vehicles. Indonesia's energy mix target in 2025 is around 23% from New and Renewable Energy (NRE). Given the importance of using NRE, Indonesia is starting to look for alternative energy that is environmentally and sustainable, like hydrogen energy. Green hydrogen technology has the potential to be developed in Indonesia. Hydrogen production processes commonly carried out are through the electrolysis of water, methanol, and biomass. The use of hydrogen can be applied to motor vehicles and power plants. Hydrogen can reduce greenhouse gas emissions. However, Indonesia has problems in developing green hydrogen technology, one of which is the high production cost, so it requires other parties to develop it.

Harvesting microalgae is an important process in gaining biomass while the remaining water is still rich in nutrients. These nutrients, mainly nitrogen and phosphorous, could cause eutrophication of water bodies (rivers, lakes, and oceans) and ecosystem degradation if discharged directly without proper treatment. Electrocoagulation (EC) is one of the harvesting methods and has several advantages: ease of operation, fast harvesting, adaptability, environmental friendliness, and low footprint. However, EC method for harvesting microalgae has the potential in producing ammonia, which is undesirable due to its threat to the environment. The purpose of this study is to establish the equilibrium of ammonium (NH4 + ) and ammonia (NH3) during Dunaliella salina harvesting. The harvesting was conducted using EC with a variation of 20 volts, 30 min, and 400 rpm. The result shows that the harvesting efficiency can reach 93.72% after 5 min of processing, decreasing the concentration of inorganic nitrogen compounds in total ammonia nitrogen (TAN) to 98.80%.
