Currently, the project “Innovation of the waste-to-energy concept for the low-carbon economy: Development of novel carbon capture technology for the thermochemical processing of municipal solid waste (CCSW – Carbon Capture and Storage from Waste)” is being implemented.
In accordance with this concept, the aim of the project is to expand upon the previously researched refuse-derived fuel (RDF) thermochemical processing (gasification) technology by (1) evaluating, studying, and adapting the most technologically and (2) economically feasible approach of pre-combustion carbon capture; and by developing a pilot-scale facility with the aim to demonstrate its potential for CCSW to offer the industry an innovative solution for municipal solid waste processing.
The project activities and outcomes are directly related to the applied research in the energy production sector and other economic fields such as public services, chemical production, and others. It directly supports the targets of Latvia’s National Smart Specialization (RIS3) strategy “Smart energy” and its related areas “Smart materials, technologies and engineering systems” and “Knowledge-intensive bio-economics” of the same strategy.
The main actions of the project include:
1) Analysis of available carbon capture methods, by reviewing the current state of the art as published in peer-reviewed literature and patents. The outcome of this activity will result in the selection of the most suitable carbon capture (CC) approach for CCSW;
2) Research of the products of RDF gasification in the context of CCSW, including characterization of syngas quality, its impact on the CC processes, and the study of the possibility to use waste-derived biochar as a sorbent for CC;
3) Engineering design and construction of the CC block that will be integrated into the existing RDF pyro-gasification unit, developed by our research group during previous projects, resulting in the demonstration facility of the application of the CCSW concept (prototype);
4) Dissemination of project results gained.
Results of the project are compiled here.
