“…In recent decades, the rapid growth of human society has brought with it an increase in pollution, in which organic waste due to the lack of solid waste collection centers is dumped around supply centers [1,2]. This situation causes discomfort to homes near these markets due to bad smells, as well as birds and rodents originating from the extensive duration of accumulation [3]. According to the World Bank, people will produce 2.2 trillion tons of solid waste in 2025 [4], of which approximately 33% will be waste that will not be managed safely [5].…”

The enormous environmental problems that arise from organic waste have increased due to the significant population increase worldwide. Microbial fuel cells provide a novel solution for the use of waste as fuel for electricity generation. In this investigation, onion waste was used, and managed to generate maximum peaks of 4.459 ± 0.0608 mA and 0.991 ± 0.02 V of current and voltage, respectively. The conductivity values increased rapidly to 179,987 ± 2859 mS/cm, while the optimal pH in which the most significant current was generated was 6968 ± 0.286, and the ° Brix values decreased rapidly due to the degradation of organic matter. The microbial fuel cells showed a low internal resistance (154,389 ± 5228 Ω), with a power density of 595.69 ± 15.05 mW/cm2 at a current density of 6.02 A/cm2; these values are higher than those reported by other authors in the literature. The diffractogram spectra of the onion debris from FTIR show a decrease in the most intense peaks, compared to the initial ones with the final ones. It was possible to identify the species Pseudomona eruginosa, Acinetobacter bereziniae, Stenotrophomonas maltophilia, and Yarrowia lipolytica adhered to the anode electrode at the end of the monitoring using the molecular technique.

Barriers and Drivers Of Biomass Renewable Energy As Co-Firing In Industrial Supply Chain With Bibliometric Analysis

Proceedings of the International Conference on Industrial Engineering and Operations Management

View full text Add to dashboard Cite

The urgent need for reductions in greenhouse gas (GHG) emissions continues to grow. Countries worldwide, including Indonesia, have started investing large amounts of resources into new renewable energy sources. Biomass co-firing can play an important role in achieving these new renewable energy objectives. It has the potential to reduce the potential environmental impacts associated with fossil fuel combustion. In the co-firing process, it is possible to reduce GHG emissions by replacing some coal with biomass during the combustion process. This article aims to identify barriers and drivers in implementing biomass worldwide through a literature review with a bibliometric analysis approach. In addition, this article will investigate the existing co-firing plants in Indonesia with the availability of available biomass resources in the country associated with the barriers that have been successfully identified. This article is very important for the development and utilization of biomass energy to generate recommendations and future strategies for biomass utilization. It is also useful for researchers to select future areas of research.
