Dr Sharon Velasquez Orta

Lecturer in Chemical Engineering


Before pursuing my academic career, I acquired experience in environmental industrial processes working with companies such as Nestle, J&J, P&G, Kimberly Clarck and Jumex. Since then, I have used a multidisciplinary approach to address current world challenges in areas related to sustainability, biomass valorisation and effective management of waste, with a specific focus on understanding biomass transformations. As part of my PhD and further academic studies, I’ve investigated how biomass can enable energy production, bacterial monitoring and wastewater treatment across multiple applications. My research over the past 10 years has focused in enabling the development of novel technologies such as microbial fuel cells (MFC) across a broad range of applications. To this aim, I have partnered with different Universities (Tanzania, Mexico, US) and companies (Palintest, Northumbrian Water) to enable these novel applications to be tested in the field. As an example, my most recent research, sponsored by the Natural Environment Research Council (NERC) has allowed us to test an inexpensive MFC in Tanzania wells, aiming to provide early monitoring of faecal contamination to rural communities.

My research involves the evaluation of new environmental technologies that can achieve both energy generation and waste remediation. I am interested in the production of renewable energy from liquid, solid wastes and microalgae by applying bioelectrochemical, chemical and thermal techniques. Inspired by the UN’s Sustainable Development Goals, my vision is to advance environmental technologies that can monitor waste pollution and that can sustainably transform waste or biomass. I lead different projects within the BioRE (Environmental bio-electrochemistry and bio-Renewable Energy) group and I am also part of the Process Intensification Group. Researchers and students that work with me participate on different seminars and engage with an interdisciplinary community working on environmental, process intensification, electrochemistry and biological engineering fields.

Areas of research:

Bio-electrochemistry Technology: Microbial Fuel Cells (MFCs) are a type of technology that enables wastewater treatment and electricity generation. MFCs utilise various organic electron donors under anaerobic conditions and directly transform chemical energy into electrical energy via a series of electrochemical reactions. I have studied the effect of different organic wastewaters, novel mediator compounds and organic loading rates on bioelectricity production, organic matter removal and microbial diversity. I am also interested into using Microbial Electrosynthesis for carbon dioxide transformation to longer chain organic molecules. In this area our group has conducted economic and sustainability evaluations, recently proving the feasibility of using bioelectrochemical reactors on fermentation tanks to convert CO2 waste emissions.

Bio-fuel Production: Biofuel can be produced from wastewater sludge and microalgae using chemical (in situ transesterification), thermal (catalytic cracking) or biological processes. These two processes offer several advantages such as the elimination of the oil extraction step, potential improvement on biofuel yield, and reduction in the transportation of intermediate products. In situ transesterification is utilised for biodiesel production while catalytic cracking can produce several types of biofuels such as methane, biodiesel and jet fuel.

Sustainable Engineering Systems: Collaboration with SECURE (Self Conserving Urban Environments): Life cycle analysis to determine the energy use and carbon emissions produced during the transportation, treatment and final disposal of solid wastes, wastewater produced in the North East of England.
