Circular Economy & Biochar & Alternative Fuels, Oh My!
Whatever your field, industry, or expertise, join us, at 13:45 CEST on Monday April 26th for EUBCE’s second plenary session: “Circular Economy & Biochar.”
Monique Axelos, Scientific Director for Food and Bioeconomy, from the French public research institute INRAE, will moderate a session about two strategic approaches to reducing global warming on a large scale will be presented – with a circular economy considered as key to the rationing of natural resources in the future.
Wageningen Food & Biobased Research (The Netherlands), as well as, the Energy Department of Polytechnic of Turin (Italy) will each be presenting.
A circular economy is considered a key component in the use of natural resources in the future. Building a biobased economy means reducing the reliance on fossil fuels, resource efficiently, full valorisation of wastes and residues, maintaining carbon and nutrient cycles, and extending high-quality use of biomass (cascading). The plenary by Vural Gursel et al. define what circularity specifically implies for biobased products and propose a list of indicators for circularity in a biobased economy. From there, a circularity assessment framework is described with a set of existing and newly proposed indicators. While existing approaches are generally limited to food, renewable energy and recycling of biowaste, work presented here aims to extend to biobased products and the extent the quality to which biomass is retained in use and subsequent cycles.
Day Two: Alternative Fuels!
The drive to find alternative fuels is strong. Tune in and learn more at 10:15 CEST on Tuesday, April 27th.
...just a few of the topics that will be covered and discussed in an accessible way during this plenary session intended for all audiences!
Biofuels, electrofuels, electric batteries, or hydrogen for aviation;
Hydrothermal liquefaction and catalytic hydrotreating;
Implications of the To-Syn-Fuel project;
New opportunities for low carbon fuels in Brazil…
Here is a strong drive to find alternative fuels for the replacement of fossil fuels and some examples of recent progress are presented in this plenary session.
A comparison of existing kerosene with a number of new fuels for aviation, including biofuels, electrofuels, electric batteries and hydrogen, is presented by Su-ungkavatin et al. Current technological status, market perspective and environmental impacts were assessed for two time horizons, 2035 and 2045. In their assessment, the authors take into account the increasing maturity of technologies in the time frames considered. For 2035, it is reported that hydroprocessed ester and fatty acid (HEFA) from waste would be the most significant pathway, whilst by 2045 alcoholic fermentation (AF) will probably be the optimum technology solution. Existing or advanced lithium ion batteries for static and mobile applications, and alkaline water electrolysis for hydrogen production are promising technologies for both time horizons.
The To-Syn-Fuel project aims to demonstrate a process for the conversion of waste biomass such as sewage sludge into renewable liquid fuels and hydrogen. Hornung et al. describe progress of the demonstration plant designed for feedstock input up to 500 kg per hour, running for 5,000 hours to produce more than 200,000 liters of biocrude oil. The process integrates thermo catalytic reforming (TCR®) with hydrodeoxygenation (HDO) and pressure swing adsorption (PSA) to produce H2-rich synthesis gas, biochar and liquid bio-oil that can subsequently be upgraded to green fuels. The authors report progress of the project in which demonstration plant commissioning is scheduled for 2021.
