Can Multiple Uses of Biomass Limit the Feedstock Availability for Future Biogas Production? An Overview of Biogas Feedstocks and Their Alternative Uses

摘要: Biogas is expected to contribute 10% of the total renewable energy use in Europe 2030. This expectation largely depends on several biomass byproducts and wastes as feedstocks. However, current development a biobased economy requires sources for multiple purposes. If alternative applications also biogas feedstocks, it becomes doubtful whether they will be available production. To explore this issue, paper aims provide an overview potential uses different feedstocks being researched literature. We conducted literature review using machine learning technique “co-occurrence analysis terms”. reads thousands abstracts from records when pairs feedstock-application are co-mentioned. These assumed represent feedstock application. reviewed 109 217 applications, revealing 1053 connections between them nearly 55,000 scientific articles. Our results two insights. First, large share streams presently considered estimates have many uses, which likely limit their contribution future Second, there not present production although proper characteristics.
