Reproduce Laboratory
The REPRODUCE – REmediation and PRODuction Using Computational and Electro(chemical) techniques – Laboratory focuses on the application of engineering principles to approach global challenges related to waste and consumer needs. Research in the laboratory employs the use of computational chemistry, process simulations, chemical and electrochemical driving forces and material science in the development of technologies, products and methods. Overall, these complementary approaches ensure the generation of solutions that are possible via thermodynamics, probable via kinetics, scalable via techno-economic analyses and sustainable via life-cycle analyses. The laboratory is housed within the Institute for Sustainable Energy and the Environment at Ohio University.

Research
Research in the laboratory is currently supported by funds from Russ College of Engineering and Technology, the Ohio Water Development Authority and the Department of Energy’s Advanced Manufacturing Office.
Wastewater Remediation
Commercial and municipal activities involve constant withdrawal of water from natural sources (lakes, rivers, aquifers etc.) accompanied with constant rejection of water to treatment facilities. This effluent water contains various kinds of waste products including chemicals, urine, toxins etc., which at the molecular level are products that can be re-used in other processes after treatment. Human waste contains unused nitrogen that is useful for agricultural applications; mining waste contains metals that can be reused for renewable energy applications; food waste contains carbohydrates and proteins that can be reused for specialty chemical production etc. In essence, wastewater – once treated – can be a source of raw materials for applications and serve as a foundation for the circular economy.
The REPRODUCE Lab is currently using electrolyte modeling and electrochemical reactor design to understand and predict conditions for optimum resource recovery from municipal wastewater with minimal process chemical input.
Polymer Upcycling
Plastic materials are ubiquitous in the consumer space and significantly contribute to municipal solid waste due to the difficulties associated with re-use/recycling. The most recalcitrant species are polyethylene, polypropylene, polyvinylchloride and polystyrene: which possess highly stable C-H bonds, account for 77% of the global plastic production but only 17% of the recycling rate. Recent efforts have explored the conversion of these recycling-resistant polymers to fuels and chemicals, with chemical products potentially offering higher economic benefits to alleviate the cost of recycling.
The REPRODUCE Lab is currently developing techniques for generating non-fuel building blocks from thermoplastic polymers via a combination of physicochemical methods including thermolysis, solvolysis and electrolysis.
Thermosetting Polymers
The first synthetic polymer material invented, phenol formaldehyde (PF) aka Bakelite, was a thermoset that is still in use today in filtration, abrasive and friction applications and globally produced at 6 million tons per year. These PF resins possess high tensile and flexural strengths, large flexural moduli and high thermal stability. In addition, PF-based composites offer structural and thermal advantages, while negating the brittleness and formaldehyde emissions associated with the base PF thermoset. In addition, opportunities exist to make these resins more environmentally benign by incorporating biomass derivative (lignin) as opposed to a fossil fuel derivative (phenol).
The REPRODUCE Lab is currently developing advanced PF thermosets through the incorporation of filler materials with similar functional groups to the PF resin to strengthen bonding.
