Sustainability of the Biowaste Utilization for Energy Production

Abstract

This article presents strategies for the development and practical modelling of biogas processes under economy market conditions. Herewith, anaerobic digestion results out of practical tests in different scales (lab to pilot) and different substrate mixtures were taken into account. Two lab-scale reactors on the one hand and pilot-scale examinations of chosen substrate mixtures on the other hand led to workable conclusions such as mixture suitability for biogas production, gas amounts and technical demands for fullscale implementation under market economy conditions. A comparison of both laboratory and pilot system performance with a full-scale biogas system has been done; herewith, the suitability of the corresponding practical process upscaling simulation has been proven. On the basis of the results, calculations regarding the necessary full-scale fermenter sizes and the required substrate amounts as well as the disposable (reusable) fermentation residues were made. The conclusion of outputs on biogas technology particularly with regard to the demand-driven production of electricity (500 + 250 kW flexible) as a special request for energy from renewable sources is given. As a further result, a general outlook and estimation for the economical implementation on a common Baltic Sea region country basis have been developed.

Valorization of Marine Waste: Use of Industrial By-Products and Beach Wrack Towards the Production of High Added-Value Products

“…Waste biorefineries are attracting significant interest worldwide as sustainable waste management solutions (Khoo et al, 2019). In this case, both required energy needs are met, and a solution to the waste management problem is found in the circular economy context (Tuck et al, 2012;Ahrens et al, 2017).…”

Technical and Economic Analysis of Municipal Solid Waste Potential for Waste to Energy Plant (Case Study: Jatibarang Landfill Semarang, Central Java, Indonesia)

“…Similar to the national condition, the waste component in the cities of Central Java is also dominated by around 60 % organic component, the organic waste has a big opportunity to be further processed either as a basic material for compost or as a biogas producer that can be utilized as a new energy source [3]. Approximately 60 % of dominance of organic matter in Indonesia is similar with Malaysia based on Khariri et al [4] Also, it has explained the negative impact of municipal solid waste landfill on human health.…”
