2 CHAPTER 1 Laws and voluntary adherences 2

3 PREMISE Respecting the environment is a choice, not only a duty Work safety and environmental protection are of prime importance for our company. In addition to being in compliance with European and National legislation, we voluntarily adhere to environmental management standards. Chapter 1 / Laws and voluntary adherences 3

4 THE LAWS The Environmental Code Our business is regulated by Legislative Decree 3 April 2006, 152 also known as the Environmental Code which promotes the quality levels of human life. This document introduced the obligation for certain industrial activities to join the IPPC (Integrated Pollution Prevention and Control) European Directive. In the Environmental Code, six intervention areas have been identified: 1 Soil Protection 2 Water Management 3 Waste Management 4 Reclaim of Contaminated Sites 5 Air Quality Protection 6 Emission Management Chapter 1 / Laws and voluntary adherences 4

5 THE LAWS Integrated Environmental Authorization In Italy, thanks to the Integrated Environmental Authorization (IEA in Italian it is indicated as AIA, an acronym that stands for Autorizzazione Integrata Ambientale ), all the licenses related to air, water, soil and acoustic impact have been unified in a single document. Monitoring is obligatory; criminal sanctions are provided for those who do not respect the set limits. Chapter 1 / Laws and voluntary adherences 5

6 Fonderie Ariotti is currently in possession of the AIA Decree nr of 2 July 2008 and of the subsequent technical attachments for the numerous ameliorative investments that were made. Chapter 1 / Laws and voluntary adherences 6

7 VOLUNTARY ADHERENCE The ISO Certification Since 2004, our company is ISO accredited. To spontaneously adhere to an international regulation allows us to increase the levels of environment protection and respect according to the activities performed within an industrial structure. The certification provides for the drafting of a manual, a virtuous environmental policy, in compliance with procedures and instructions as well as in the pursuit of improvement and goals which are renewed from year to year. Chapter 1 / Laws and voluntary adherences 7

8 CHAPTER 2 Transforming Elements 8

9 CONSUMPTION AND WASTE Anatomy of a business process By analyzing our industrial processes, we have identified a series of input and output elements for each production phase. The elements that are significant for the impact the have on the environment have been included in a monitoring program, and classified as follows: Input Elements Electric Energy Fuel Water Raw Material Output Elements Emission in the Atmosphere Water Discharge Waste Noise Pollution Chapter 2 / Transforming Elements 9

10 RESULT ANALYSIS Contextualized Data In order to reflect on how to take full advantage of energy supplies, raw materials, and reducing waste, we can share some numbers. The data that we illustrate in the following chapters are not directly related to production. The annual variations are therefore conditioned by the production curve of the previous years. Chapter 2 / Transforming Elements 10

11 CHAPTER 3 The Values of Air Emission 11

12 LAW PARAMETERS The limit values authorized by AIA The foundry processes emanate a series of substances into the air which must be checked every year with a sampling of the filters and which are measured in mg/nm 3. The values of the emissions must result below the authorized limits of the AIA (Integrated Environmental Authorization). The table below represents its main parameters. Chapter 3 / The Values of Air Emission 12

13 TABLE FOR THE AIA LIMITS The substances and their own limit values [mg/nm 3 ] COV* Phenols IPA* Carbon Monoxide Nitrogen Oxide PCDD + PCDF* Total Dust Particles Free Crystalline Silica , , *COV Volatile Organic Substances / *IPA Polycyclic Aromatic Hydrocarbons *PCDD + PCDF Polychlorodibenzodioxins and Polychlorodibenzofurans. These compounds are given in nanograms [ng/nm 3 ]. Chapter 3 / The Values of Air Emission 13

14 THE COMMON PARAMETER Focus on Dust Particles Among the different substances listed in the previous slide, the dust particles represent the common parameter for all casting processes. All other parameters refer to only a few emissions. The casting processes are listed as follows: Fusion processes Shaping and Flask Removal processes Deburring, Sandblasting and Cast Finishing processes Chapter 3 / The Values of Air Emission 14

15 Fonderie Ariotti constantly monitors the total dust content of the main emissions through a system based on triboelectric probes. Chapter 3 / The Values of Air Emission 15

16 The results of the investigations carried out annually show that all monitored parameters are always lower than the allowed limits (10 mg/nm 3 ). Chapter 3 / The Values of Air Emission 16

18 CHAPTER 4 Rainwater Control 18

19 SAMPLE ANALYSIS The Determination of the Wastewater Limit Meteoric waters, along with water from yards and roofs, are collected in a common basin. Every six months, a sample is taken from an external laboratory to ensure that our company meets the limits set out in the next table for sewage water. Chapter 4 / Rainwater Control 19

20 TABLE FOR THE LIMIT VALUES Parameter Limit value [mg/l] Parameter Limit value [mg/l] Suspended solids 25 COD 100 Chromium (Cr) 1 Iron (Fe) 2 Nickel (Ni) 0,2 Lead (Pb) 0,1 Copper (Cu) 0,1 Zinc (Zn) 0,5 Sulfate (SO4=) 500 Phenols (C6H5OH) 0,1 Aldehydes (H-CHO) 0,5 Hydrocarbons, Total - Chapter 4 / Rainwater Control 20

21 CHAPTER 5 Limits for Noise Level 21

22 FONDERIE ARIOTTI / Environmental Statement INVESTIGATIONS IN THE COMPANY Noise Effects The investigations on noise emissions do not follow a fixed schedule but are carried out after each new installation or after a plant change. Such investigations are conducted within the industrial perimeter, making sure to consider the possible presence of nearby receptors (houses, residential areas, etc ). The values that we determine are compared with the limit values established by the law in the local area where the company is sited. Chapter 5 / Limits for Noise Level 22

23 TABLE OF LIMIT VALUES Zone division Day-time limit ( ) Special Protected areas 45 db 35 db Residential areas (predominantly) 50 db 40 db Mixed range areas 55 db 45 db Areas of high human activity 60 db 50 db Industrial areas (predominantly) 65 db 55 db Industrial areas (alone) 65 db 65 db Night-time limit ( ) Settlement in Zone No. 6 From 2014 onwards the settlement of the Fonderie Ariotti SpA is located in Zone No.6, according to the modification of the zoning plan for noise pollution in Zone No. 6, approved by the city of Adro (Brescia). This zone belongs to a purely industrial area. Chapter 5 / Limits for Noise Level 23

24 CHAPTER 6 Waste Management 24

25 Our foundry pursues an important policy of waste management, in order to increase the reuse and reduce the percentage of waste intended for final disposal. Chapter 6 / Waste Management 25

26 THE WASTE OF THE FOUNDRY CER Classification All waste that comes from the foundry processes is classified according to the "European Waste Catalog" (the so-called CER code), as defined by EU Directive No. 75/442/CEE. The different typologies of waste coming from the foundry are listed as follows: Foundry Molds and Cores (CER ) Cast Waste (CER ) Dust from devices for Emission Control (CER ) Dust from Combustion Gases ( ) Coating and Refractory materials coming from Metallurgical processes (CER ) Chapter 6 / Waste Management 26

27 We are always looking for new technologies that allow us to recycle the waste we dispose of. Chapter 6 / Waste Management 27

28 MOLDS, CORES AND CASTINGS Reuse in other fields The main waste of the foundry process, such as CER (molds and cores) and CER (casting), are reused after prior treatment in other industrial areas. A project for the reuse of combustion gases CER is currently under development. Chapter 6 / Waste Management 28

29 TABLE OF PRODUCTION AND REUSE VALUES Our Waste The diagram shows the amount of waste produced in the past two years, which has been eliminated or recycled. Chart Legend Production [ton/year] Disposal [ton/year] Recycle [ton/year] Chapter 6 / Waste Management 29

30 F O N D E R I E A R I O T T I / Environmental Statement THE ACHIEVED GOAL Approx. 90% Recycled Waste 10% As you can see from the chart, all waste from our foundry processes were recycled or reused in up to 90% of the Chart Legend cases in Percentage of Waste Disposal 90% Chapter 6 / Waste Management Percentage of Waste Recycling 30

31 CHAPTER 7 Consumption values 31

32 ELECTRICITY Power supply for Melting Furnaces More than 70% of electricity use is attributable to the use of the melting furnace. The remaining 30% is based on the typical power consumption of an industrial company. Two electric furnaces with a current consumption of 2.8 and 4.5 megawatt [MW] are used in a foundry. According to the data analysis from 2015, the electricity consumption can be divided as follows: 1 Electric Stove kwh 11 + Remaining Power Consumption = kwh 111 Total kwh Chapter 7 / Consumption values 32

33 TABLE OF POWER CONSUMPTION Value per ton Electricity (consumed by kilns) per ton (gross) [kwh/ton] In order to get an idea of the efficiency of the melting process within the foundry, every year we compare the electricity consumed by the furnaces (expressed in kwh) with the annually produced tons The following chart shows the development of this indicator over the past 4 years Chapter 7 / Consumption values 33

34 METHANE Rotary Kiln, Boilers and Burners The methane consumption within the foundry is mainly due to the use of the rotary kiln with a capacity of 6.7 MW. The use of this rotary kiln varies from year to year depending on production requirements. The remaining part comes from the use of boilers, burners and dryers for molds. What follows is the methane consumption data registered in 2015: 1 Rotary Kilns Sm = Boilers Sm 3 Other Sm 3 1v Total Sm 3 Chapter 7 / Consumption values 34

35 WATER A Predominantly "Domestic" Application In a foundry, the use of industrial water is not expected, exception made for the cooling circuits (cooling towers) and the water that is used in the mechanized molding process. The m³ of water used in this process are, however, a fraction of the total consumption, mainly for domestic use (showers, irrigation, photovoltaic module cleanse). The water consumption distribution in m³ for the year 2015 is calculated as follows: 1 Watering 212 m = Domestic use 2619 m 3 Cooling circuit 3922 m 3 1v Total m 3 Chapter 7 / Consumption values 35

36 95% of the water used for the cooling of the production plant is reused by the recovery circuits. Chapter 7 / Consumption values 36

37 EQUIPMENT PRODUCTION Our Commitment to Environmental Protection Our foundry has two photovoltaic plants installed respectively in 2008 and The plant produces a total of 408 kw: equivalent to 10% of the capacity installed in the company, and is equal to the power used by 130 apartments. The following table describes the performance, the annual energy production and the reduction of CO2 emissions for each of the two plants: Plant Installation Year Power [kwp]* Generated Energy [kwh/anno] CO2 Reduction [ton/year] Fotovoltaico 1 Dicembre ,5 Fotovoltaico 2 Dicembre , ,5 *kwp (peak power) indicates the power in kilowatts in conditions which allow the installation s highest performance levels.
