Municipal solid waste unit production rates and estimation of the required number of waste storage containers in the municipality of Athens
General
The Municipality of Athens (M.A.) currently comprises 7 municipal districts, 7 waste collection districts (WCD) and approximately 5800 residential blocks. Solid waste is collected daily on a 7 days per week basis. The M.A. comprises approximately 119 waste collection sub-districts (herein referred...
Photocatalytic disinfection of water polluted by Pseudomonas Aeruginosa
General
Photocatalysis by titanium dioxide (TiO2) is a water treatment method. Pseudomonas aeruginosa is a microorganism resistant to chlorine and UV-C irradiation. TiO2 photocatalytic technology can destroy bacteria, which are resistant to oxidative destruction of cell membrane caused by sole UV...
The distribution of Cd and Cu in sediments covered with algal mat
General
In coastal marine environments, with shallow, warm and calm waters, it is sometimes possible to observe the presence of organosedimentary structures that are commonly flat and laminar in shape. These structures are called algal mats or recent stromatolites due to their remarkable similarities to...
Route optimization for solid waste collection: Trabzon (Turkey) case study
General
In a municipal solid waste management system, decreasing collection/hauling costs, which consist of 85 % of total disposal expenditure, can be carried out by a route optimization. Thus, a huge amount of economical benefits is getting furnished. If route optimization is performed in solid waste...
Tracing dispersed coaly-derived particles in modern sediments: an environmental application of organic petrography
General
A crucial aspect in environmental sciences is related to the transportation, accumulation and fate of solid organic particles not native to the sediments. In this study we present the petrographical features of seven sediment samples obtained from aquatic environments in Sweden, Finland and The...
Hydrochemical characteristics of the Gallikos River water, Prefecture of Kilkis, Greece
General
The Gallikos river basin is located in the northern part of Greece and discharges into the Thermaikos Gulf, North Aegean sea. Three main tributaries contribute to the river, the basin of which has a total areal extent of 930 km2. The basin of Gallikos river is formed of metamorphic rocks, limestones...
European trends in the feedstock recycling of plastic wastes
General
Consumption of plastic products has increased dramatically over the past few decades. This trend results in the generation of a vast waste stream that needs to be properly managed to avoid environmental damage. Increasingly stringent European legislation is setting new standards that promote the...
Biohydrogen production from sweet sorghum biomass using mixed acidogenic cultures and pure cultures of Ruminococcus Albus
General
The present study focuses on the exploitation of sweet sorghum biomass as a source for hydrogen in continuous and batch systems. Sweet sorghum is an annual C4 plant of tropical origin, well-adapted to sub-tropical and temperate regions and highly productive in biomass. Sweet sorghum biomass is rich...
Water quantity and quality monitoring of Kosynthos river, North-Eastern Greece
General
An investigation of the quantitative and qualitative characteristics of Kosynthos river flow is presented. Four monitoring sites were established along Kosynthos river for the period October 2003 to October 2005 where discharge and water quality parameters were monitored. River flow processes have...
Characterization of packaging grade papers from recycled raw materials through the study of fibre morphology and composition
General
The restrictions in availability of forest-based raw materials along with favourable environmental policies towards alternative sources of raw materials have forced corrugated packaging industry to shift towards recycled paper and other fibre sources such as non-wood and agro-residues. The...
