Characterization of packaging grade papers from recycled raw materials through the study of fibre morphology and composition

by

Adamopoulos S., Martinez E. and Ramirez D.

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...

Hygroscopic property of Neem (Azadirachta indica A. Juss.): an experimental determination of the Shrinkage characteristics

by

Akpan M.

General

A pioneer effort is made in this study to carry out an experimental determination of shrinkage characteristics of neem (Azadirachta indica A. Juss) wood on its linear, volumetric, and coefficient values with the hope of ascertaining its utilization potential as timber. Three study locations were...

Evaluation of pollutant loading in the runoff waters from a major urban highway (Gdansk Beltway, Poland)

by

Polkowska Z., Skarzynska K., Dubiella-Jackowska A., Staszek W. and Namiesnik J.

General

Runoff water is an important medium transporting various air pollutants from the air to the surface water. This paper presents the results of measurement of removal rates of anions and cations in the rain, road runoff, throughfall and surface water near a major urban highway (Gdańsk beltway). The...

A GIS model for landfill siting

by

Despotakis V.K. and Econopoulos A.P.

General

The use of Geographical Information Systems (GIS) for Landfill Sitting is studied. The necessary spatial information required to determine the candidate sites for any type of terrestrial area (Community/Prefecture/Region/Country) is examined. This spatial information is then used for site selection...

Denitrification as a component of Nitrogen Budget in a Tropical Paddy Field

by

Pathak B.K., Iida T. and Kazama F.

General

The direct assessment of denitrification suffers from a number of problems. A mass balance model is simple and widely accepted to calculate nitrogen (N) loss as a denitrification component. The objective of study was to estimate the potential N loss a denitrification from a tropical paddy in the...

Performance monitoring of a vertical flow constructed wetland treating municipal wastewater

by

Gikas G.D., Akratos C.S. and Tsihrintzis V.A.

General

A two-year monitoring program was undertaken in a vertical flow constructed wetland treating wastewater from Gomati, a village in Chalkidiki, North Greece. This constructed wetland operates since 2003. The monitoring campaigns were organized every 15 days. Water quality samples were collected at the...

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...
