3 PROMECO EXTRUDER SYSTEM PES 600 The PES - Promeco Extruder System - is the simplest, most flexible, efficient and effective solution to the problems of agglomeration and volume reduce compacting to produce briquettes and pellets. The flexibility of this machine allows the treating of different materials. PES systems have been successfully used to process: Mixed plastics, paper and cardboard, textiles and wood Commercial waste and waste residual from sorting plants Industrial solid waste similar to municipal waste Plastics (PE, HDPE, EPS, PP, PVC, car fluff of polymers etc.) Mix composed by the constituents of the typical inorganic fraction of MSW used as RDF (lightweight plastics, textiles, wood, paper and cardboard); Car fluff after pre-treatment plant Wood waste and green waste The applications of PES system are endless. Amongst them: Production of RDF pellets (thickened or briquettes) Production of profiles and/or finished goods (e.g. spacers for pallets; poles for agriculture, wheel stoppers for cars; profiles for walls, structures and insulation; curbs outdoor) Agglomeration of mixed plastics Pre-treatment of the organic fraction for composting Production of peat substitute from wood waste PES have been successfully used upstream of traditional extruders, exploiting their characteristics to pre-treat the material. More specifically, PES are particularly suitable for the pre-treatment of materials in output from washing lines (packaging films, agricultural films). Our standard production Screw diameter: 300 or 600 mm Motor (with inverter): 90, 315 or 400 kw Power consumption 50-60% of power motor installed Production: from 350 to kg/h or 30 m 3 /h Matrix type: M (for pellets), F or V (for briquettes) or C (for compost)

4 Main Applications Input Plastics, paper and cardboard Shredded fluff Urban solid waste dry fraction Mixed plastic Organic and green waste PROMECO EXTRUDER SYSTEM exerts pressure and friction on the material with consequent heat generation. This changes the materials structure and shape.

6 TO PULP EVERY KIND OF FIBROUS MATERIAL System flexibility Waste usually has different size, water content, density and variable composition: Bioextruder system has been designed to handle this difference in the best way. The control system, based on the PLC logic, continuously checks the most important parameters as current and temperature on the plate of the machine and then sets the working process automatically. Input material Organic waste Biomass material (Biomass culture for Anaerobic Digestion process as corn, general seeds cultivate for bio-energy production, straw) Wood scraps Compost oversize Bark Products Organic substance for anaerobic digester The output product is an organic material ground and ready to be eaten and attacked from the anaerobic bacteria, during the anaerobic process. Advantages of the treatment with Bioextruder Continuous process Increase of biogas yield +50% No water required Low maintenance cost Peat substitute Lignocelluloses ground material with high density, specific weight from 140 to 200 kg/m³, chemical and physical parameters similar to those of the peat and analogous utilization in agriculture, floriculture and topsoil segment.

7 PROMECO BIOEXTRUDER C-MATRIX TO DEFIBER Bioextruder Promeco is the simplest, easiest and the most efficient solution for the organic fraction treatment. The technology comes from Promeco Extruder System machine used for several years in plastic and waste treatment. Treatment capacity Compost The output of the Extruder is a mixture with characteristics of high reactivity compared to the raw material, and this is mostly due to: Increased porosity with higher oxygenation capacity Significant increase of the specific surface available for the aerobic bacteria Structural optimization of the composting material Reduced moisture content Advantages of the treatment with Bioextruder Compost and organic fraction for anaerobic digestion Treatment capacity depends on the mixture composition, on the structure and on the final size of the product required: it varies between 25 and 40 m³/h. Peat substitute According to the requirements of the product and to the characteristics of the lignocelluloses waste, it varies between 20 and 40 m³/h. Great reduction of the composting time process Less surface required for the composting process

9 PROMECO BIOEXTRUDER M OR F-MATRIX PROMECO TECHNOLOGY FOR PELLETIZED COMPOST BRIQUETTES FROM BIOMASS Promeco technology is able to produce pelletized compost to be improved as fertilizer for agricultural soils with time extended release of organic matters. Thanks to PES machine, whose technology is patented and unique worldwide, it is possible to turn compost into a stabilized product with potential agronomic advantages. The PES allows to compact fibrous material as straw, olive pomace, bovine, suine or chicken manure, fruit and vegetable waste or their mixture producing biomass briquettes to be used into biomass furnaces, gasifiers and technologies for electrical and heat power production. The treatment capacity is up to 4 ton/hour, the significant reduction of input volumes, the high quality briquettes production are just a few examples of the several advantages of processing the agricultural waste with PES. Input material Biomass material Straw, olive pomace, bovine, suine and chicken manure, fruit and vegetable waste and other fibrous materials Compost Products Pelletizer biomass To be burnt into biomass furnace To be gasified For electrical and heat power production Compost in pellet The output of the Promeco Extruder System is a pelletized compost with more benefits than those of traditional compost Advantages of the treatment with Bioextruder Time extended release of fertilizer substances Easy storage Other applications: Composite animal feed production Pelletizer fertilizer production Strong treatment of composting of green waste Pelletizing the biomass for gasification process

10 BRIQUETTES FROM EVERY KIND OF MATERIAL

11 PROMECO EXTRUDER SYSTEM PES FOR BRIQUETTE PRODUCTION F OR V-MATRIX FROM MSW/RDF, CAR FLUFF, HOSPITAL WASTE FOR GASIFICATION OR TO BE GRANULATED TO GET RDF The PES V or F matrix briquetting machine is the most simple, flexible, efficient and effective solution to the problems of densification and sintering. The extreme flexibility of the machine allows processing of different materials. PES has been used successfully to treat: Mix of plastics, paper and cardboard, textiles and wood MSW dry fraction Industrial solid waste (similar to urban waste) Mix composed by the typical constituents of the dry fraction of municipal waste used as RDF (lightweight plastics, textiles, wood, paper and cardboard); Car fluff system flexibility Waste is characterized by the inconsistence of its quality. Moisture, density, composition and size can vary significantly. The PES was designed to automatically compensate for any fluctuations, in order to maintain the production rate as stable as possible or the quality of the output. The main motor is generously oversized in order to maintain the production rate even in the presence of material more "difficult" to treat. Under normal conditions, however, is used 60% of installed capacity. The control system, based on PLC, continuously monitors several parameters, including electrical power consumption and temperature of the extruded material, in order to adjust the operations of the machine accordingly. The control action is based on these principles: Decrease in electrical power consumption: the speed of the augers of the feeding bunker is increased, in order to maintain a constant production rate Increase in electrical power consumption: the control system acts on the matrix of extrusion, by opening the top, allowing an easier flow of material. Decrease in the temperature of the material, below a desired value: the control system closes the matrix extrusion, decreases the speed of the augers of the feeding bunker, reduces the motor speed. Increase in the temperature of the material: the control system opens the extrusion matrix, increases the speed of the augers of the feeding bunker and increases the speed of the main motor Input material Non-reusable fractions MSW, paper, cardboard and plastic Optimum size of about 40x40 mm. Average humidity 15% max up to 20-23% depending on the characteristics required for the briquettes. Homogeneous mixture of materials with minimum 25% of a low melting point plastics (LDPE polyethylene film). Thermoplastic and thermosetting waste Mixed plastics similar to heterogeneous melting point (low melting point / melting high) Polyethylene washed, unwashed also mixed with other materials, polypropylene, PVC, ABS, polycarbonate Car fluff from auto shredder residues (ASR) Material to process consists mainly of a mix of plastics, elastomers, rubber parts, textiles, protective coatings, electrical cables, glass, soil fractions and non-ferrous materials in general. The requirements that such a mix must satisfy in order to ensure the effectiveness of the extrusion process are essentially: Optimum particle size of about 40x40 mm, easily achieved with a pre-grinding. Max humidity up to 20-23% depending on the characteristics required for the briquettes. Products RDF briquettes The briquettes have different shapes, sizes from mm, an average degree of compactness and high adherence. Briquettes can then be ground (in a shredder without grate) to obtain a mix of high density material with a variable size 5-80 mm, particularly suitable for fluidized bed furnaces. Specific gravity between 0,4 and 1,2 kg/dm³. Moisture content ranging between 2 and 11% depending on the composition of the refusal to start. Advantages resulting from treatment with PES: Strong decrease of the times of densification of the product. Fewer machines to install and manage, and relative reduction of investment costs Small areas occupied Minor electric power installed and used Simplified maintenance Increased productivity and versatility of the system Low running costs and operation of the plant Production capacity Capacity changes depending on the characteristics of the treated waste and the desired output; it can reach kg/h.

12 System flexibility Normally the waste have different size, water content, density and composition variable so the PES densifier has been projected to handle this difference automatically in the best way. The control system, based on the PLC logic, continuously checks the most important parameters as current and temperature on the plate of the machine and then arranges the working process automatically. Input material RPF fluff Plastic content > 10% Moisture < 35 % Products Pellet Output size of the melted material from 25 to 60 mm Water content < 1% Density > kg/mc Completely homogenized

13 PROMECO EXTRUDER SYSTEM PES FOR PELLET PRODUCTION M-MATRIX PELLET FROM MSW/RDF FLUFF: Ø20 30MM TO BE USED IN CEMENT PLANTS OR TO BE GRANULATED IN ORDER TO GET RDF The Promeco Extruder System M matrix is the simplest, easiest and the most efficient solution for plastic densification and agglomeration. Capacity The treatment capacity depends mainly on the characteristics of the input plastics and on the required density of the product: it can reach kg/h. Advantages of the treatment with PES densifier Less space required for the equipment Lower power installed and used than normal system Simplified maintenance time and costs High productivity and versatility Low management and operation cost

14 System flexibility Normally the waste have different size, water content, density and composition variable so the PES densifier has been projected to handle this difference automatically in the best way. The direct combination between the machine PES and the traditional Extruder allows the proper feeding of the material into the single shaft shredder and guarantees an homogeneous production. The control system, based on the PLC logic, continuously checks the most important parameters as current and temperature on the plate of the machine and then arranges the working process automatically. Input material Thermoplastic plastic and plastic waste Mix plastic with similar melting point PE from washing line, PE, PVC, PP,EPS, Tetrapack scraps Al+PE or mix of different polyolefin Products Melted plastic Output size of the melted material from 25 to 60 mm Water content < 1% Completely melted and homogenized Plastic melted output Plastics (LDPE, HDPE, PP, EPS, PVC, polylaminated scraps Al+PE, etc.)

15 PROMECO DENSIFIER M-MATRIX FOR WASTE MIXED PLASTIC, WASHED LDPE The densifier Promeco Extruder System is the simplest, easiest and the most efficient solution for plastic densification and agglomeration. The flexibility of the system can process different plastics as: Mix plastics as scraps, industrial & commercial and waste plastics Plastics (PE, HDPE, EPS, PP, PVC as foil shredded, powder or similar) Capacity The treatment capacity depends mainly on the characteristics of the input plastics and on the required density of the product: it can reach kg/h. Advantages of the treatment with PES densifier Mixing and homogenization of different polymers Homogenous and continuous melting Output product completely dry Degasing on Promeco Extruder System and therefore not necessary in the traditional extruder Less time required to melt the product than standard system Fewer machines to install and manage, and relative reduction of investment costs Less space required for the equipment Lower consumption of power (around 0,092 kw/kg of plastic processed)

16 RDF FROM MSW Input waste: Municipal Solid Waste Industrial waste Output material: RDF The plat must be implemented with production of briquettes, allowing to densify and to establish the shape and density of the RDF Advantages of Promeco RDF production systems Possibility of using only the fractions with higher calorific value as fuel, to produce a quality RDF Getting a stabilized RDF that, thanks to its shape and density, can be temporarily stored, allowing more flexibility in the management of production operations and in the conveyance of the product. This "unties" the value of RDF from needs of users in the short term enabling to defer the conveyance according to the market demands Recovering of some valuable materials for recycling Limiting landfill only to fractions or unsuitable material recovery or energy recovery, with reduced volumes from the preliminary grinding

23 MAIZE SILAGE PRE-TREATMENT FOR ANAEROBIC DIGESTION The lignocellulose rich material as straw, wheat and maize silage can be mechanically crushed into fibers through the Promeco Bioextruder, so that their surface area accessible to the bacteria increases. This treatment is necessary before AD to destruct the lignocellulosic structure and to release sugar contained in the biomass. Input waste: Maize silage Biowaste from agriculture Wheat Straw Green waste (i.e. hops) Output material: Open fiber material optimal for anaerobic digestion, features: Open fibers Low density Small particle size High homogenity Advantages of the treatment with Promeco Bioextruder Increasing of the digestion of maize silage of over 40% (considering 12 days retention time). The study has been carried out by the University of Linköping, Sweden. To produce 1 MWh power ton/year of extruded maize silage are needed instead of ton/year of unextruded material.
