Review ArticleOpen accessEvery word in the titleProspects of Using Wastewater as a Resource-Nutrient Recovery and Energy GenerationMusfique Ahmed, Chowdhury Kamrul Hasan, Hafizur Rahman et al.It is well understood that both untreated and partially treated wastewater comprise substantial amount of resources, which can be recovered and utilized for different purposes. Since Waste Water Treatment Plant (WWTP) is energy intensive and expensive, substantiating the WWTPs with Resource Recover Technologies (RRTs) will not only save a considerable amount of energy but also make the environment cleaner and … …American Journal of Environmental Sciences, Vol. 11, Issue 2 · 25 Jun 2015 · 8,183 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Processing Methods on Nutrient Composition of Black Soldier Fly Larvae Reared on Slaughterhouse Waste and Rice BranNurul Isnaini, Faizal AndriBlack Soldier Fly (BSF) larvae have emerged as a sustainable and nutrient-dense resource for livestock feed, primarily due to their high protein and lipid contents. However, the nutritional composition of BSF larvae is substantially influenced by the processing methods. This study aimed to evaluate the effect of five processing methods (room dried, sun dried, oven dried, microwave dried, and roasted) … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 3 · 4 Dec 2025 · 3,071 accessesView PDFCite
Research ArticleOpen accessIn the keywordsImpact of Shrimp Farm Effluent on Water Quality in Coastal Areas of the World Heritage-Listed Ha Long BayThuyet D. Bui, Jim Luong-Van, Chris M. AustinProblem statement: Shrimp farming has rapidly developed in coastal areas of the World Heritage-listed Ha Long Bay since the last decade. Effluent discharged from shrimp farms with high levels of nutrient waste may cause eutrophication in receiving waterways. Therefore, assessing water quality at tidal creeks receiving shrimp farm effluent in coastal areas of Ha Long Bay supports environmental protection and … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 3 Mar 2012 · 11,283 accessesView PDFCite

Research ArticleOpen accessIn the abstractIn Sacco and in vitro Evaluation of Heating and Formaldehyde Treated Protein FeedAnnisa Rosmalia, Idat Galih Permana, Despal, Toto ToharmatMassive protein conversion into ammonia in the Rumen (RDP) should be avoided to prevent protein quality deterioration. Heating and formaldehyde treatments are commonly used to decrease Rumen-Degradable Protein (RDP), but it rarely used to protect local feed. We aimed to compare the effectiveness of heating and formaldehyde treatments in decreasing the RDP of local feed. The use of fistulated cattle, … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 1 · 12 Feb 2024 · 6,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractBioconversion of Corn Steep Liquor to Biofertilizer by Symbiotic FermentationXiaojie Ren, Zhuangzhuang He, Huihui Peng et al.Corn Steep Liquor (CSL) is wastewater from corn starch industry. The huge amount generation made it as a serious environmental problem. But CSL is nutrient-rich with diverse amino acids and other trace elements. In this study, symbiotic biofertilizer was studied using CSL as main substrate.
