Operational guidelines for emissions control using cross-correlation analysis of waste-to-energy process data Open
The aim of this study was to develop a data analysis method which could provide operational insights and guidelines waste-to-energy (WtE) plant operators. A method to filter outliers with changing properties was combined with a cross-corre…

Machine learning based modelling for lower heating value prediction of municipal solid waste Open
Municipal solid waste (MSW) is a heterogeneous and complex fuel. Time-resolved knowledge of its physical and/or chemical properties is key to ensure stable Waste-to-Energy (WtE) plant operation. For this purpose, Gaussian processes regress…

Butanol Production from Lignocellulosic Sugars by Clostridium beijerinckii in Microbioreactors Open
Background: Butanol ( n- butanol) has been gaining attention as a renewable energy carrier and an alternative biofuel with superior properties to the most widely used ethanol. We performed 48 anaerobic fermentations simultaneously with glu…

Butanol production from lignocellulosic biomass: revisiting fermentation performance indicators with exploratory data analysis Open
After just more than 100 years of history of industrial acetone-butanol-ethanol (ABE) fermentation, patented by Weizmann in the UK in 1915, butanol is again today considered a promising biofuel alternative based on several advantages compa…
