Impact of bulking agents on municipal solid waste refused derived fuel

The main objective of this study is to investigate how the bulking agents (BA) effect on municipal solid waste (MSW) moisture contents and refused derived fuel (RDF) pellets bulk density (BD), durability (DU) and hardness. In this experiment applied sugar cane trash, rice husk and cotton waste bulking agents each at 15%, 25%, 35% and 45% to reduce the moisture contents of MSW for RDF pellet development. Sugar cane trash was prominent in moisture reduction capability in 10 days than others BA. MSW and sugar cane trash mixture, RDF pellets pertained maximum BD (1.58 g/cm3), DU (99%) and hardness (27kg) were developed with compaction process, die diameter 8inch and 120◦C. It was also observed smoke appeared at 150◦C during pelting process due to burning of biomass. Furthermore bulking agents had also revealed effectiveness in BD, DU, hardness results as the quantity of BA increased. It was concluded that BA are suitable for moisture reduction and RDF pellet development, can be sued as an alternative energy fuel.&#x0D; Bangladesh J. Sci. Ind. Res. 57(2), 77-84, 2022</jats:p

Freshwater salmon aquaculture in Chile and transferable antimicrobial resistance

Large amounts of antimicrobials are used in salmonid aquaculture in Chile. Most are used in marine aquaculture, but appreciable amounts are also employed in freshwater aquaculture. Much research and many publications have examined transferable antimicrobial resistance in bacteria isolated from marine salmon farms, but much less attention has been paid to this area in freshwater salmon farming. A recent paper by Domínguez et al. (2019) has as least in part remedied this situation. We now comment on some of its interpretations and have attempted to point out its areas of strength and weakness in light of the published scientific literature. Seen in this setting, the important results presented by Domínguez et al. (2019) underline the need for increased awareness of the challenge to animal and human health posed by excessive use of antimicrobials in aquaculture
