An extensive analysis of the possibilities and goal in the application of composites as an alternative to thermoplastic polymer composites filled with minerals has been presented. The analysis was made taking into special consideration the mechanical properties and applicability of polypropylene composites, which are widely used and well characterized. It was shown that the enthusiasm and expectations linked with the vision of the application of thermoplastics filled with plant fibers from widely available renewable sources as cheap materials with attractive properties has not been fully justified. The realistic solution would be maintaining the production of these new materials derived from waste polyolefins and renewable fiber materials from agriculture and forestry industries for low-end applications.

URBANREC project aims to develop and implement an eco-innovative and integral bulky waste management system (enhancing prevention, improving logistics and allowing new waste treatments to obtain high added value recycled products) and demonstrate its effectiveness in different regions. In URBANREC project, Northern, Mediterranean, Eastern and South-eastern areas in Europe are represented by Belgium, Spain, Poland and Turkey, which have very different urban waste recycling rates, from around a 60% in Belgium, 25-30% in Spain, or 20% in Poland, to less than 5% in Turkey. URBANREC project aims to improve the separation and disassembling of bulky waste - implementing advanced fragmentation techniques to obtain high quality raw materials, promoting innovative valorisation routes for those considered more problematic (PUR foam, mixed hard plastics and mixed textiles), not recycled due to lack of eco-innovative cost-effective solutions. The waste treatments considered in the project include i) rebonding and chemical glycolisis for the PUR materials, to prepare renewable adhesives, ii) needle felt to obtain isolation panels from textiles, iii) fibre reinforced composites from textiles, iv) wood Plastic composites (WPC) and v) catalytic hydro-gasification with plasma for mixed hard plastics to obtain chemicals or fuel. These treatments will be optimized and implemented at industrial level thanks to the collaboration of the URBANREC partners: top Research Institutes at EU level, and companies interested in obtaining novel eco-friendly products from waste, under a circular economy approach. All relevant actors in the waste management chain in every country have been also involved as project partners (local authorities and city amenity sites in Belgium, Spain, Poland and Turkey) guaranteeing the implementation of the proposed solutions at local level, adapting them to suit the particular characteristics of each area, ensuring the replication at EU level

Three soils (8 profiles) from various regions of Poland were extd. successively with EtOH-PhH (1:1 mixt), H2SO4, NaOH, and NaHC03 + Na2S2O4 to remove humic and fulvic acids and det. the fractional compn. of humus. The org. acids were mostly free or weakly bounded with Fe and Ca.

Microbial fuel cell (MFC) consisting of 3 (anodic, cathodlc and nourishment) chambers was Inoculated with anaerobic fresh or adapted sludge and used for studying its properties. The catholyte consisted of K 3Fe(CN)6, KH2PO4, and NaOH. The anolythe (nourishment) was a glucose soln. Electrochem. characterization of MFC was carried out by cyclic voltammetry, chronopotentlometry and spectroscopic electrochem. impedance measurements. The MFC accomplished max. values of voltage 721 mV and power d. 71, 9.10-2 W/m2. The Internal resistance of MFC was 3 Ω.

Sixteen samples of Polish ferro-muck, ferro-mucky, ferrohumIc and ferro-mucous soils taken from 4 sites (depth up to 48 cm) were studied for elementary compn., extinction (color) index and content of functional groups (COOH, OH). The humic acids from bog iron ore levels contained more C and O but less N and H than those from the surface levels.

A review, with 36 refs., of ecotoxiclty hazards connected with use of fullerens, nanotubes and nanopartlcles of Ag, TiO2, Au and Se.

Sixteen polycyclic arom. hydrocarbons (PAH) were detd. in Industrial sewage sludges from PKN Orlen, Plock, PL, In 2002-2004 and In 11 mono and dicotyledonous plants growing on the sludges. The sludges contained up to 1639 μg/kg of total PAH (main component benzo[ghi] perylene up to 555 μg/kg). The highest content of total PAH (377 μg/kg) was obsd. in yarrow (mainly phenanthrene 90 μg/kg). The dicotyledonous plants showed higher ability to accumulation of PAH comparing to monocotyledonous ones. The 3 and 4 ring PAH were accumulated more intensive than the 5 and 6 ring PAH.

Air pollution with SO2, NO2 particulate matter PM10 and O3 in Poland was described with an air quality index (AQI) both in the whole country and In particular regions. A decrease in values of sub-indices for all studied pollutants (esp. of SO2) averaged over the country In 1997-2009 years was obsd. The average AQI decreased also and was lower than 1 since 1998 (about 0.6 in 2007-2009). The highest AQI was found for the Silesian region (0.8-1.0 in 2007-2009).

Review of ecotoxicological studies required in European programs: REACH and review program for active substances used in biocidal products, is presented.
