The Ward agglomeration method for cluster analysis and Pearson coefficient were employed evaluate distance-based similarity measure optimize methods estimating methane emissions as well verify input parameters In order calculate content biodegradable organic parts waste,...

As a waste neutralization facility, the landfill is kind of bioreactor producing gas or (LFG) -biogas, which should be captured and neutralised for environmental reasons.One ways its utilisation combined production heat electrical energy in power (CHP) cogeneration systems.For that purpose, assessment efficiency unit was undertaken this work on basis performance over last 5 years.The analysis CHP system demonstrated ratios range at lower limits units up to 0.5 MW.The fuel chemical conversion...

Waste from street cleaning is usually of a fine fraction below 10 mm and varies greatly in both quantity composition. It may be composed chlorides, especially for that resulting during winter due to the use de-icing agents. Chlorides can cause salinization surface water groundwater, soils, which turn lead deterioration purity decrease biodiversity aquatic organisms, changes microbiological structure, increases toxicity metals. Therefore, it very important determine level salinity stored...

Combined heat and power generation is the simultaneous conversion of primary energy (in form fuel) in a technical system into useful thermal mechanical (as basis for electricity). This method offers high degree efficiency (i.e., very efficient fuel to energy). In context transformation, combined (CHP) fundamental pillar link between volatile electricity market market, which enables better planning. article presents an advanced model production mixtures based on landfill biogas use CHP units....

One key issues involves placement objects, events conducted spatial (geographical) analyses through application GIS technology...

Abstract The paper deals with the problem of recycling and a review field handling polymeric materials is carried out, on basis which commonality for European space their disposal problems shown. Ways solving them are identified leading dynamics approaches to waste management compared national ones revealed. It shown that tempos formation wastes practically coincide processing, indicates an increase in technogenic load environment as result continued influx into it. structure species...

The paper provides general information on selected methods of joining aluminum sheets. main focus is the strength friction stir welding connection and energy consumption process. practical part study used alloy 2024-T3, most commonly in automotive industry. consisted FSW two pieces overlapping sheet metal, using different process parameters. thickness was 1 mm. After completed, test specimens were broken a testing machine. During tests, appropriate parameters at which weld showed highest...

Abstract The present state of the environment in rural area has been analyzed. main factors which led to existing situation have revealed. structure Ukraine’s crops and amount accumulated waste Ukraine influencing agricultural landscapes areas dependence between incidence within time interval was As a result calculations, we received social losses due an increase morbidity population living impact landfills, coefficient ecological stability studied territories calculated it found that...

Standard methods for assessing the environmental impact of waste management systems are needed to underpin development and implementation sustainable practice. Life cycle assessment (LCA) is a tool comprehensively ensuring such covers all impacts associated with management. LCA often called "from cradle grave" analysis. This paper integrates information on greenhouse gas (GHG) implications various options some most common materials in municipal solid (MSW). Different treatment MSW were...

Landfill biogas becomes an important factor in elimination of fossil fuels as a result fast- growing use renewable energy sources. The article presents analysis operation the plant where landfill was utilized for production. average annually (gross) productions electric and heat at were 1217 MWh 1,789 MW, respectively. calorific value 17 MJ/m 3 , which corresponds to 4,8 kW/m . According measurements actual readings acquired during cogeneration unit, it can be stated that CHP system has been...

The paper presents advanced computational solutions for selected sectors in the context of optimization technology processes as an innovation and progress improving energy efficiency smart cities. main emphasis was placed on critical urban infrastructure, including particular use algorithmic models based artificial intelligence implemented supervisory control systems (SCADA-type, Virtual SCADA) technological involving sewage treatment (including wastewater systems) waste management systems....

Selection of a waste management strategy for region is difficult decision that must take into account various frequently contradictory targets and tasks. This article presents the use multi-criteria analysis estimating selecting most profitable selection regional-metropolitan system. The final solution should ecological, economic social aspects consideration. It was established solutions chosen needed to ensure following: stream reduction, acceptance, efficiency index.

The process of shaping distribution network structures is one the most fundamental design tasks, and determines delivery certainty media transported by them. It especially crucial with reference to elements a critical character, such as roads or water supply, sewage, electrical networks. In urban conditions, geometric these has quasi-chaotic character that individual for each city. complexity networks increases significantly size city, therefore evaluation also difficult issue. Despite many...

Abstract Poland was collected 9.6 million tonnes of municipal waste in 2012 (plus update). The primary method dealing with organized depositing them landfills.
