1. PLOIESTI MECHANICAL-BIOLOGICAL TREATMENT PLANT Environmental protection Department ing. Dragos Manu

2. Mechanical-biological treatment plant Mechanical-biological treatment plant (TMB Plant) - will be placed on administrative territory of the Municipality of Ploiesti and the sorting station will be located on the city's administrative area Boldesti - Scaeni. Ploiesti TMB Plant is located about 1.8 kilometers from the inhabited area of Ploiesti City, residence of Prahova County of and the main source of waste generation, on the right side of County Road DN1A, road that connect Barcanesti village with Ploiesti city. Road access is done through the County Road DN1A. On the proposed site there are no important ecosystems, the land is arable. The total area of Ploiesti TMB Plant is of about 7 hectares, the land is situated in the inner site. In terms of geomorphology, land can be characterized as a transition zone of the piedmont plain, consisting of deluvial deposits of dusty materials - sand mixed with gravel.

3. Biodegradable waste Target for biodegradable waste storage in 2013 is represented by reducing the amount deposited by 50% compared to the total amount deposited in 1995. Thus, the maximum amount of biodegradable waste that can be stored in 2013 is 92,262 tons of biodegradable waste, which means that about 115,717 tons of biodegradable waste will be diverted from storage. For 2016, the maximum amount of biodegradable waste that can be stored is 64,583, which means that about 148,655 tons of biodegradable waste will be diverted from storage. Diverting biodegradable waste from storage will be achieved by sorting and recycling of paper, cardboard and wood waste and by the mechanical-biological treatment of organic fraction of municipal waste, both in centralized facilities and by individual composting in households.

4. Targets at county level for TMB Plant efficiency Specific objectives for TMB plants In accordance with the EU Directive regarding landfills and national targets for recycling, some of the specific objectives for TMB plants are: 1. Waste pre-treatment before storage; 2. Diversion of biodegradable and non-biodegradable municipal waste before storage, by mechanical separation of waste in materials for recycling and/or energy recovery (waste-derived fuel, RDF); 3. Diversion of biodegradable municipal waste from storage by: - Reduction of dry aggregation before storage; - Reduction of biodegradability before storage; - Stabilization in a compost product (CLO = Compost Like Output, or “biostabilized waste"), for land planning and/or - Transforming in biogas;

5. PROJECT PARAMETERS Categories of residual waste (biodegradable and others) resulted and presented in the waste management system in Prahova county are: - waste residues from both urban and rural - residual waste from the public domain (gardens and parks, markets and streets). Collection system proposed in the project is targeting for the residual waste - individual waste bin for residual waste for households or a collection point for residual waste for apartments blocks - individual bin for biodegradable fraction of rural households in about 60% of the individual households - separate containers for biodegradable fraction coming from gardens and parks - separate containers biodegradable fraction coming from markets - street residual waste containers. Input flow

6. Technical options for biodegradable waste treatment Analysis of the Feasibility Study and Financing Applications showed that from all of the technical options to treat the biodegradable waste the most feasible is a mechanical - biological treatment plant. Mechanical-biological treatment method (TMB) is a residual waste processing system that involves both mechanical and biological processes. So the mechanical-biological treatment process proposed for the residual waste in the Feasibility Study will consist of two phases: - mechanical pre-treatment - stabilization of biodegradable material in a biological phase composed of aerobic decomposition stage and maturing stage.

7. Capacity of TMB Ploiesti Plant • TMB Ploiesti Plant capacity will be of 150,000 tons/year and this quantity will be collected from proposed areas for collection. • Taking into account the small amounts of green biodegradable waste (from gardens, parks and markets) compared with the residual waste from the population, the outcome of TMB plant will be mainly of LOC (LOC = Compost Like Output, or “biostabilized waste"), used in activities as coating material in landfills, degraded or polluted areas, mine closings, etc.. • CLO estimated in the TMB Plant will be of 35.750 tons/year • Good quality compost estimated in the TMB Plant will be of 2.000 tons/year. • In time, if the market development will require larger quantities of good quality compost, TMB Plant will be able to process larger quantities

8. Components of TMB Plant TMB Plant is formed by the following components: • Administrative area; • Mechanical treatment area; • Biological treatment area – stage 1 of decomposing; • Biological treatment area – stage 1 of maturation. TMB Plant will treat residual waste collected from collection areas and will consist of: • the stage of mechanical treatment; • biological treatment stage: aerobic decomposition; • maturation platform for 50% of the resulted quantity from the aerobic decomposition phase.

9. Technical specification • Mechanical pre-treatment stage was sized to a quantity of 150,000 tons/year, operated 260 days per year, with two shifts per day and a total of 16 hours per day. • The amount to treat on one working day is 575 tons/day and 38 tones/hour. • The volume is 1918 cubic meters treated daily. • Biological treatment phase - the phase of decomposition has been dimensioned to input a quantity of 112,500 tons/year and a percentage of reduction of 33%. • Biological treatment phase - the phase of maturation has been dimensioned to input a quantity of 37,500 tons and a percentage of reduction of 5%. Sizing calculations were performed at the stage of Feasibility Study for each stage of mechanical-biological treatment .

10. Residual waste follow the next technological flow • Weighting the residual waste at their access inside the plant; • Discharging the waste from rubbish carts or containers from transfer stations, in a temporary storage area; • Waste preparation stage (for biological stage) is composed by: • > Manual separation of bulky waste; • > Filling the sacks opener bin; • > Reducing the size using one of the following techniques: • - hammer mill, where the dimensions are significantly reduced by the hammers hitting; • - chopper - rotating knives or hooks are spinning at slow speed but high torque, allowing waste shredding; • - ball mill - a rotating drum fitted with heavy balls to reduce the size of waste; • >Waste separation by various means: • - jiggles and riddles; • - magnetic separators for ferrous metals; • - separators in Foucault current for non-ferrous metals; • - ballistic separators; • - optical methods for separation.

11. Mechanical treatment stage Waste will be discharged in the temporary storage area, a first separation of the bulky waste will be done manually. At the end of the mechanical treatment we will have the following fractions:

12. Biological treatment • Biological processes can transform the biodegradable fraction in compost type product, and/or in biogas and/or in biostabilized fraction to be stored. • In TMB Ploiesti Plant, it is foreseen a process of aerobic decomposition divided in 2 stages: • A first stage – of intensive aerobic decomposition with air blasting at the bottom, static, indoors; • A second stage – of maturing under a metal shed for 50% of the estimated quantities of the first stage (the remaining 50% will be transported to the landfill where they will be matured in the warehouse even before compaction)

14. The buildings/rooms of TMB Plant • The buildings/rooms of TMB Plant will be the following: • Administrative building/containers; • Mechanical treatment room composed of 2 technological lines; • Biological treatment buildings/chambers for aerobic decomposition stage; • Maturation room. • The administrative area will be composed of two containers, one administrative and one sanitary container that will serve a number of 33 employees per day • Mechanical treatment room will be positioned in the vicinity of the TMB Plant entrance and weighting area. • Mechanical treatment room will be metalic and will include two technological lines with adequate equipments. • Mechanical treatment building is a covered metalic building, with an estimated surface of 4.757 sqm.
