Microbial community dynamics and stability assessment during green waste composting

by

Gazi A.V., Kyriacou A., Kotsou M. and Lasaridi K.E.

General

Green waste (leaves, grass and shredded twigs) was composted for 5.5 months in a wooden composting bioreactor, of 1 m3 capacity, using both passive convective aeration, facilitated by the design of the bioreactor, and manual turning. Temperature was measured daily, while samples were analysed for...

Tertiary Physico-chemical Treatment of Secondary Effluent from the Chania Municipal Wastewater Treatment Plant

by

Tassoula E., Diamadopoulos E. and Vlachos Ch.

General

The present study investigated tertiary physico-chemical treatment of the secondary effluent from the Chania municipal Wastewater Treatment Plant (WTP). Laboratory experiments were carried out with the aim of studying coagulation efficiency regarding reduction of turbidity, soluble COD and...

Investigations on disposal of low-calorific landfill gases by a small scale fluidised bubbling bed combustion plant

by

Steinbrecht D., Wolff H.-J., Matzmohr R., Nassour A. and Didik H.

General

Poor landfill gases cannot be used to drive gas engines or be burnt in gas flares. This follows why the combustion flame front velocity for poor gases becomes very low. From this moment the non-flammable poor landfill gases are polluting the environment. An energetical utilisation of very poor...

Three eco-tool comparison with the example of the environmental performance of domestic solar flat plate hot water systems

by

Martinopoulos G., Tsilingiridis G. and Kyriakis N.

General

Life Cycle Analysis (LCA) is a procedure used as an analytical tool for the evaluation of the environmental impact caused by a material, a manufacturing process or product. For an end product, LCA requires both the identification and quantification of materials and energy used in all stages of the...

Pre-treatment of industrial landfill leachate by Fenton’s oxidation

by

Petruzzelli D., Boghetich G., Petrella M., Dell’Erba A., L’Abbate P., Sanarica S. and Miraglia ... View all

General

Biological treatment (aerobic and anaerobic) of industrial landfill leachate is limited by the presence of toxic contaminants (e.g., heavy metals) and recalcitrant (biopersistent) organics (e.g., polyphenols, pharmaceuticals, cosmetics, etc.,), hindering viable conditions for biomass proliferation...

Alternative fillers for use in slurry seal

by

Oikonomou N. and Eskioglou P.

General

Slurry seal is applied for low-cost paving and surface maintenance. The principal materials used to create slurry seal are aggregates, asphalt emulsion, water and fillers like Portland cement (mainly), lime and other materials. This paper presents the use of alternative fillers instead of expensive...

Analysis on the MSW thermal degradation processes

by

Marculescu C., Antonini G. and Badea A.

General

The waste to renewable energy source has become a priority in the wastes treatment field. The research goal is not only the wastes destruction but also a better thermal energy recovery from the processes. The municipal solid waste presents a high heterogeneity degree from the dimensional point of...

Transport and accumulation of heavy metals in undisturbed soil columns

by

Ermakov I.V., Koptsik S.V., Koptsik G.N. and Lofts S.

General

The podzolic soils of the Kola Peninsula, Russia, have in localised areas been highly contaminated with copper and nickel from smelting activities. Migration and retention of these metals were investigated in undisturbed soil columns irrigated with simulated background and polluted precipitation in...

On leakage from the near-surface radioactive waste storage facility

by

Konstantinova M., Gudelis A. and Butkus D.

General

Maisiagala RADON type radioactive waste storage facility was commissioned in 1963 in a marshy, ecologically sensitive locality, where soluble radionuclides easily can penetrate and migrate with groundwater. To assure the requirements of radiation safety, the analysis of radionuclide leakage from the...

Available Cd content of salt-affected and normal soils of Halastra-Kalohori area

by

Matsi Th., Hatzigiannakis E.G., Arampatzis G.K. and Panoras A.G.

General

A survey was conducted in order to evaluate the levels of available (DTPA extractable) Cd in salt affected and normal soils of Halastra−Kalohori area, located in N. Greece. In this area, phosphogypsum (PG) (a byproduct of P fertilizer industry, occasionally enriched with Cd) has been used as...
