the Biological Recovery and Utilization of Resources from Waste in Space Habitat
the Biological Recovery and Utilization of Resources from Waste in Space Habitat
Developing resource recovery technologies for space exploration bases, including nitrogen and phosphorus extraction from urine and methane recovery from organic solid waste.
Establishing life support systems using bioleaching and biomining, such as recovering rare earth elements from e-waste and extracting minerals from simulated lunar regolith.
Utilization of resources recovered and extracted from organic and electronic waste in the space environment for plant cultivation.
Exploring the feasibility of food production under low-pressure conditions by utilizing waste resources and lunar regolith in the space environment.
Conducting metagenomic analysis of microbial communities in ISRU systems to monitor genetic traits and resistance mechanisms.
Ensuring the stability of biological resource circulation in closed environments with continuous monitoring, machine learning-based forecasting, and expert feedback networks.
Antibiotic resistance gene (ARG)
Antibiotic resistance gene (ARG)
Every year, usage of antibiotics are increasing and antibiotic resistant bacteria(ARB) or genes(ARGs) are appearing in Wastewater treatment plants. It has became a worldwide problem due to the potential threat of super-bug.
We are analyzing the proliferation mechanisms and fate of ARBs and ARGs during the treatment of livestock manure and wastewater using non-culture-based analytic methods, such as qPCR, digital PCR, and metagenomics.
Direct INTERsPECIES Electron Transfer (DIET)
Direct INTERsPECIES Electron Transfer (DIET)
DIET helps microorganisms to directly transfer electron between each other by bridging them together with conductive materials. This mechanism can reduces lag phase within the reactor, and it increases gas production under stressful conditions.
Attaching magnetite to anaerobic granule can increase the retention time of the magnetite within the reactor. Reducing washout of conductive material which is major problem with DIET. Also, Low strength ultrasonication was applyed for additional attachment of magnetite to granules.
Nano particle synthesis
Nano particle synthesis
Silver based nanoparticle synthesis employing agro-byproducts and further applications in medical area.
Toxicity of hydrophonic wastewater
Toxicity of hydrophonic wastewater
Nutrient solution generated from hydroponic system is sterilized with AOP process, and removal efficiency of toxic substances such as root exudate were experimented with plant germination and growth.
Biomass fule by Torrefaction of swedge sludge
Biomass fule by Torrefaction of swedge sludge
Due to the establishment of the mandatory RPS quota, the usage of sewage sludge solid refuse fuel(SRF) is increasing in power plant and power generating companies.
Sewage sludge produced from sewage treatment plant and waste crop from farmland were used to produce solid fuel.
Also, we are researching technology to optimize quality of produced solid fuel, and reduce generation of odor and dust from the process.
Investigation of water pollution in hydroponic farms and management plan
Investigation of water pollution in hydroponic farms and management plan
With the development of technologies such as smart farms and hydroponics, residual fertilizer components are being discharged to rivers, soil and ground water. These contaminations are being investigated to accumulate data for solution to meet the emission standard in accordance with total water pollution
Studies on mass balance of microplastic in the freshwater and calculation of inflow factor
Studies on mass balance of microplastic in the freshwater and calculation of inflow factor
Microplastic is considered as emerging environmental issue as major aquatic pollutants in rivers. We are participating ing an environmental technology development project to develop predictive modeling of microplastic behavior in freshwater. Also, research is conducted to calculate the material balance and inflow coefficient database through microplastic sampling, pretreatment, and analysis of Han river water system.
Ex-situ biomethanation of h2 /co2 in a trickle bed reactor
Ex-situ biomethanation of h2 /co2 in a trickle bed reactor
Ex-situ biomethantion utilizes H2 and CO2 produced from outher sources to create methane from reactors such as trickle bed reactor. Experiment was conducted to investigate the feasibility of ex-situ biomethanation using industrial CO2 and digested manure as nutrient source
