The paper deals with the evolution of Environmental Impact Assessment (EIA) in Greece within the last 25 years, how EIA tool has been implemented since 1986, when the first legislative framework related to EIA was enacted, and therefore, it discusses the main deficiencies and their causes. The new legislative framework, the Law 4014/2011 'Environmental Appraisal of Projects and Activities', is briefly presented, emphasizing on innovative aspects and proposals, aiming at better, faster and more effective for environmental protection procedures. Finally, the paper ventures to predict how successful the Law 4014/2011 will be in ameliorating EIA decision-making by public authorities, ensuring effective environmental protection and linking developers with locals, whose opinions are of vital importance for successful environmental management.

Planning is strongly related to sustainable development, while it entails a participative democratic political system, in order to be considered as an effective tool for the conservation of resources and pollution control. Environmental impacts of development plans' proposals may be assessed with the aid of Strategic Environmental Assessment, which was firstly introduced in Greek legislation in September 2006, as a result of the relevant European Union Directive 2001/42EC. In this paper, the strategic environmental impacts of the Amfipolis Municipality Development Plan are identified: for this reason, the crucial environmental parameters of the study area (ecologically sensitive areas, archaeological sites, cultural and economic activities) are refereed, proposals related to land-use zones are presented, and all future projects that may be constructed as a result of the planning study implementation, are identified.

The paper deals with liquid manure treatment and valorization, deriving from small decentralized livestock farms, by the implementation of anaerobic digestion. For the purpose of the research, a pilot plant has been constructed that consists of an anaerobic digester with volume V = 10m3. For biogas exploitation and utilization, a biogas storage tank has been constructed, with volume V=3.90m3, together with a system for chemical treatment of H2S, by the aid of Fe2O3 A heat generator has been connected for thermal utilization of biogas. Both experimental units operate in series. The influent BOD concentration in the described system has been measured at 8600 mg/L. The BOD concentration and total volatile solids (TVS) are diminished by 58% and 40% respectively in an HRT of 18-22d. The final results, as far as treatment is involved, show that for the liquid phase the treatment after anaerobic digestion reaches an exit BOD of 3610 mg/L. Salmonella sp is zero and E. coli is 570 cfu/mL (< 1000 cfu/mL) therefore the effluent has undergone hygienization. Source
