| The biogas unit under investigation is a specially designed portable assembly biogas unit and is sought to be widespread and commonly used in Egypt by the Egyptian Environmental Affairs Agency (EEAA). This unit is able to anaerobically treat different types of organic wastes, which are: food waste, kitchen waste, and waste from landscape. The main objective of this study is to perform an environmental impact evaluation of the implementation of this biogas unit. The specific greenhouse gas (GHG) emissions of using the produced biogas from the unit for electricity and heat generation were calculated, where the methodology of life cycle assessment (LCA) was applied. The results show the GHG emissions for each component of the biogas unit and each process... |

| Abstract Large quantities of kitchen waste are produced in modern society and its disposal poses serious environmental and social problems. The aim of this study was to isolate degradative strains from kitchen waste and to develop a novel and effective microbial agent. One hundred and four strains were isolated from kitchen waste and the 84 dominant strains were used to inoculate protein-, starch-, fat- and cellulose-containing media for detecting their degradability. Twelve dominant strains of various species with high degradability (eight bacteria, one actinomycetes and three fungi) were selected to develop a compound microbial agent "YH" and five strains of these species including H7 (Brevibacterium epidermidis), A3 (Paenibacillus polymyxa), E3... |
