The paper presents selected results that rely on the basic work carried within previous projects initiated by the Romanian Government and sets directions for present and future research. Four industrial branches and the representing/linked R&D institutions participated at the implementation stage with their selected processes: textile industry (cotton fibres dying), next to pulp and paper branch (special paper production), chemical industry (urea synthesis), and metallurgical industry (lead oxide - PbO production). Cleaner production assessment (CPA) was the basic instrument applied. Improvement options with no-cost, low- and medium-costs were identified and their implementation was initiated on a very short-term. The industry-specific indicators were calculated at the project start (level O) and after 2 or 3 months of implementation (level 1). As expected, processes from different industries showed different improvement potential. Although some indicators varied significantly from one branch to another it was interesting to find that some others situated at comparable values for all four industries, disregarding their specifics. The results were intended to be used at the Government level (Ministry of Economy) also at the branch level, setting thus a starting point for benchmarking between industries at the national economy level, and between units within the branch. One important outcome was issuing the Guidelines for promoting Eco-efficiency in industrial development (still on the Ministry web-site).

The study presents experimental data on phytostabilizationl phytoremediation of 5.57% total petroleum hydrocarbons contaminated soils, using plants of the Achillea millefolium species. Studies have been conducted on pots placed in outdoors in three experimental variants in the absence/presence of an additional treatment: 1. Contaminated soil; 2. Contaminated soil treated with fertilizer agent, stabilized sewage sludge; 3. Contaminatedsoiltreatedwith fertilizer and amendment base on indigenous volcanic tuff with clinoptilolite. After five months of growth the plant roots have formed a strong twinned network throughout the vegetation soils of volume pots. The content reduction of the total petroleum products in the contaminated soil was 45.4% and 65.4% for the variant of contaminated soil treated with fertilizer agents, anaerobically stabilized sewage sludge from the municipal treatment plant in the absence/presence of the amendment with indigenous volcanic tuff. Soil polluted with petroleum hydrocarbons does not reduce the total content of phenolics and antioxidant capacity of Achillea millefolium crop; rather it can be boosted when the soil is treated with stabilized sewage sludge and indigenous volcanic tuff.

The phytostabilization of the slag and fly ash dumps was studied in an experimental block consisting of variants fertilized with different organic fertilizing agents, sewage sludge or biological sludge resulting from a slaughter house in the absence/presence of a bacterial organic stimulus. The bacterial organic stimulus was used during the sowing stage and subsequently through regular foliar applications on the grown crop. The used bacterial stimulus Biocomplex 900 is based on a marine brown algae extract provided by SC EKO GEA EAST SRL, Romania. In this paper, the germination degree of Lolium perenne seeds was studied at the same time with the coverage degree of sown areas. The plant development and the amount of biomass harvested were monitored. The slaughter house sludge used (0.5kg·m2) with the addition of Biocomplex 900 stimulus determined a rapid vegetation in the fertilized variant along with biomass harvests which was 2-3 times higher than in other variants.
