ICEC 2022 - Speakers

Scientific Part

Dr. Lutgarde Raskin

University of Michigan

Environmental biotechnologist. One of her interests lies in harnessing the power of microorganisms for water treatment and resource recovery from waste streams. Most of the research projects she works on address aspects of the microbiome of the engineered water cycle to improve human health through sustainable design approaches. Other areas of interest include resource recovery from waste streams and microbial aspects of drinking water systems, including biofiltration, disinfection, distribution, and biostability of sanitation systems.

Dr. Matthew Scarborough

University of Vermont

Dr. Scarborough's research focuses on the application of microbiomes (aka, microbial communities) to protect the natural environment and public health. He currently focuses on management of wastes from agricultural processes with the goal of harnessing microbiomes to convert renewable feedstocks to valuable products. This work aims to provide additional revenue for farmers while reducing water and air pollution. Dr. Scarborough's work encapsulates many scales, from studying the function of individual enzymes to implementing full-scale microbiome-based conversion platforms.

Dr. Heike Sträuber

Helmholtz Center for Environmental Research

The aim of Dr. Sträuber's work is systematic material and energy flow analyses in the anaerobic digestion process to produce carboxylate platform chemicals (especially medium-chain and iso fatty acids) or methane. Indications of preferential or critical material flow in the system under certain conditions (substrate, reactor operation) are provided. This is intended to identify indicators of stable or unstable conditions in the process, which should lead to measures to improve the respective production processes in yield and stability.
In addition to stirred tank reactors, the focus is primarily on solid-state fermentation systems with percolation with various substrates (Nawaros and residual materials) in batch and semi-continuous processes. 

Xiaoyu Zhu

Chengdu Institute of Biology

Here research Focus lies on the production of biofuels and biochemicals, including:

  • Production of medium-chain carboxylic acids from organic waste streams

  • Microbial CO2 fixation and conversion to value-added products

  • Anaerobic digestion

Byoung-In Sang

Hanyang University

His research Focus lies on the folowing topics.

  • Biochemical Engineering
  • Biofuels
  • Cellwater and Wastewater Treatment

Anca Delgado

Arizona State University

Dr. Anca Delgado received a Ph.D. in Microbiology from Arizona State University and is currently an Assistant Professor of Environmental Engineering in the School of Sustainable Engineering and the Built Environment and the Biodesign Swette Center for Environmental Biotechnology at Arizona State University.  She is a Principal Investigator in the National Science Foundation (NSF) Engineering Research Center for Bio-mediated and Bio-inspired Geotechnics (CBBG).  Dr. Delgado’s research focuses on microbial processes for contaminant treatment and environmental restoration.  Dr. Delgado’s interest in microbial chain elongation has been centered on its occurrence in the natural environment and its role in H2 production to support dehalogenation reactions.

Industrial Part

Juan Guzman


Capro-X, is a sustainable ag-tech startup, spun out of Cornell. The company is focused on scaling up a sustainable fermentation technology that upcycles dairy wastes into clean water and green alternatives to unsustainable palm oil chemicals.

Nils van Stralen


ChainCraft develops and exploits proprietary fermentation processes to produce biochemicals from organic waste. The first product range, C4-C8 Medium Chain Fatty Acids (MCFA), can be used in existing and new applications in animal feed, lubricants, plasticizers, polymers, coatings and flavours and fragrances. 

Shivani Garg


LanzaTech is changing how people think about carbon, with the option to recycle a “liability” into valuable and sustainable new products. The company's carbon recycling technology is like retrofitting a brewery onto an emission source — pollution is converted by bacteria into new fuels and chemicals. Imagine a day when your plane is powered by recycled GHG emissions, when your shampoo bottle started life as emissions from a steel mill. This future is possible today using LanzaTech technology and LanzaTech’s CarbonSmartTM IP licensing services.

Kirsten Herben-Steinbusch


Kirsten is a serial entrepreneur in biotech with a track record in growing early stage biotech innovations to VC funded companies Chaincraft and Based on her PhD, she co-founded Chaincraft in 2010 while being motivated to make a difference. She strives to offer cost effective alternatives for fossil based chemical by renewable alternative produced by fermentation. As CEO she raised over € 15M funding and lead successfully technical and commercial developments reaching technical maturity up to demo scale. Since 2021, she became CTO of and is responsible for the scale up and international market introduction of a new cost-effective biomanufacturing platform. 



Cesar Granda

BioVeritas LLC

His background is bio-process and biochemical engineering in the biomass and waste utilization area. His focus for the past 25 years has been the deployment and scale up from laboratory to demonstration scale of the conversion of biomass to useful fuels and chemicals using the carboxylate platform, as well as recovery of protein from under-utilized proteinaceous streams.  Dr. Granda is the Chief Technology Officer of BioVeritas, a company that employs the carboxylate platform for the production of bioingredients and sustainable materials and fuels.

Opinion piece

Prof. Dr. Ramon Ganigué

Ghent University

Environmental Engineer. Interested in anaerobic microbial procesess ofchain elongation, microbial electrosynthesis and sewer corrosion and mitigation. Publishes e.g on new reactor microbiomes connected to separation technologies as well on pure culture characterisation.


Associate. Prof. Dr. Ir. David Strik

Wageningen University & Research

Currently his research group pioneers on 'Engineering Open-Culture Waste to Resource Fermentation & Separation Biorefineries. Waste streams like heterogenous organic waste, CO2, rhizodeposits, syngas and plastics are used in fermentations as well as electricity driven biotechnologies to produce chemicals like medium chain fatty acids. The chemicals can be used a feed-additive, plant-growth promotor, or pre-cursor for biodegradable plastics, fuels and more.


Prof. Dr. Ir. Cees. Buisman

Wageningen University & Research

His research focuses on the following topics, among others.

  • Medium chain length fatty acids, sustainable building block from organic waste
  • Capacitive Deionization for energy-efficient drinking water production
  • Selenium bio-recovery (removal) from wastewater to low ppb levels

Prof. Dr. ir. Lars T. Angenent

University of Tübingen, Germany

Environmental biotechnologist. One of his interests is the recovery of carbon with open cultures (reactor microbiomes), defined mixed cultures, or pure cultures of microbes. He is promoting the carboxylate platform as an important platform in biorefineries because water and nutrients must be recycled while bioenergy yields must be maximized. He is leading a research group on chain elongation and is entrepreneurial as, for example, a co-founder of Capro-X.
