ENVIRONMENTAL STATEMENT <strong>2009</strong><br />

SIGNIFICANT DEVELOPMENTS<br />

IN <strong>2009</strong><br />

We continued to believe in alternative energy<br />

resources<br />

In <strong>2009</strong>, SunEdison - the leading player in the photovoltaic solar<br />

sector in North America, which was acquired in November by<br />

MEMC Electronic Materials Inc. - received the necessary permits<br />

for developing and building a photovoltaic park in the province<br />

of Rovigo, which is in the Veneto region of Italy.<br />

With an installed capacity of 72 MW, the park will be the largest<br />

in Europe, as it will surpass two current European “megaparks”<br />

in Olmedilla, Spain (60 MW) and Strasskirchen, Germany (50<br />

MW).<br />

With such capacity, the system will generate enough energy in its<br />

first year of full operational capability to power 17,150 homes,<br />

thus contributing to “not release” 41,000 tons of carbon dioxide<br />

into the atmosphere: the equivalent of taking 8,000 cars off the<br />

road.<br />

We continued to develop know-how and<br />

efficiency<br />

With investments in projects for creating new “niche” products<br />

for applications of microelectronics, such as image sensors; with<br />

innovations in new plant systems with the best environmentally<br />

sustainable solutions; with a commitment to developing FBR - an<br />

energy-efficient technology for growing polycrystal; and with the<br />

construction of a district heating system. These projects actively<br />

involved our personnel, who incorporate the environmental variable<br />

into every idea aimed at developing and improving the<br />

company.<br />

We continued to respect the environment<br />

and the laws that protect it, as demonstrated<br />

by the information contained in<br />

this report.<br />

We continued to work hard to improve<br />

our local area<br />

In <strong>2009</strong>, we took a series of steps which we hope will improve<br />

and strengthen our relationship with our local area - with schools,<br />

through projects whose purpose is to share our know-how on<br />

technology and sustainability with students; with the municipal<br />

government and the public transit company, through preparation<br />

of a “Plan for Home-Job Commuting” for our staff, whose goal is<br />

to help reduce traffic on local roads by promoting good habits<br />

such as car pooling, bicycling and public transit (for the future,<br />

we’re even considering agreements with local businesses for selling<br />

electric bicycles to our employees); and through sponsorships<br />

of local sports associations.<br />

ENVIRONMENTAL STATEMENT <strong>2009</strong><br />

DIRECT ENVIRONMENTAL ASPECTS<br />

Energy Resources<br />

The energy sources used in the <strong>Merano</strong> factory include electrical<br />

energy, fuel oil, diesel fuel and natural gas.<br />

Electrical energy accounts for almost all the energy consumed<br />

by the factory (see Table 2) and is mainly used in processes<br />

involved in the growth of (poly and mono) silicon crystals,<br />

the hydrogenation of TET into TCS, and the production of hydrogen.<br />

Electricity is supplied at high voltage and then transformed<br />

in on-site electrical substations for internal uses at medium and<br />

low voltage.<br />

Graph 2 shows data on the factory’s overall energy consumption<br />

in absolute and specific terms (expressed in TOE or<br />

Tons of Oil Equivalent) for each ton of silicon produced. Tables<br />

2 and 3 and Graphs 3 and 4 show the data broken down<br />

into separate energy sources.<br />

In <strong>2009</strong>, overall consumption noticeably increased due to increased<br />

production, while specific consumption was virtually the<br />

same as in the previous year.<br />

Fuel oil with a low sulphur content is used to feed the boiler,<br />

which heats the thermal oil used in processes that purify and<br />

recycle chlorosilanes.<br />

Diesel fuel and natural gas are used to heat some of the<br />

factory buildings which are not served by the cooling water recovery<br />

system. Diesel fuel is also used in company vehicles (for<br />

internal movement, and for the emergency team), and to power<br />

emergency generators.<br />

Notes on the units of measurement used<br />

Starting this year, in compliance with EMAS III regulations, the GJ<br />

is used as the unit of measurement for energy consumption and<br />

energy efficiency.<br />

The following conversion factors were used when calculating the<br />

various indicators in joules:<br />

• 1 MWh = 3.6 GJ (for electrical energy)<br />

• 1 TOE = 41,868 GJ (for fuels)<br />

(sources: IEA; ENEA; World Energy Council)<br />

The decision to start from TOE when expressing fuel consumption<br />

in GJ was based on two “practical” reasons: most importantly,<br />

because MEMC must still report its energy consumption figures<br />

in TOE to FIRE every year, so these values must in any case be<br />

calculated by our Energy Manager; furthermore, unambiguous<br />

formulas for calculating energy consumption in joules from other<br />

units of measurement were not found for all the fuels used by the<br />

company. For example, Legis. Decree no. 115 dated 30 May<br />

08 and directive EC/32/2006 on the efficiency of final uses of<br />

energy and energy services provides conversion factors only for<br />

fuel oil and natural gas.<br />

Energy consumption in TOE is calculated by applying the following<br />

conversion factors, as set out in MICA memorandum<br />

no. 219/F dated 2 March 1992 “Article 19 of Italian Law no.<br />

10/1991“. Obligation to name and receive an annual report<br />

from a Technical Specialist responsible for the conservation and<br />

intelligent use of energy”:<br />

• Diesel fuel: 1 t = 1.08 TOE<br />

• Fuel oil: 1 t = 0.98 TOE<br />

• Natural gas:<br />

1000 Nm3 = 0.82 TOE<br />

• Electrical energy supplied at high voltage:<br />

1 MWh = 0.23 TOE.<br />

Table 4 lists data on the collection of groundwater for industrial<br />

use and for obtaining drinking water. The collection of groundwater<br />

is also shown in Graph 5.<br />

In <strong>2009</strong>, no significant changes occurred in the consumption of<br />

water for industrial use or for obtaining drinking water.<br />

In particular, drinking water is still used mostly in the cafeteria,<br />

in bathrooms, and for testing emergency fixtures (showers and<br />

eye washing stations). The increase in absolute terms in the consumption<br />

of drinking water as compared with previous years was<br />

caused by its additional use by personnel from outside firms who<br />

were working in the construction site that was opened to expand<br />

the facility.<br />

Table 5 and Graphs 6 and 7 show the trend in specific consumption<br />

of chlorosilanes and hydrogen as compared with the year<br />

2000, which is used as the year of reference.<br />

Likewise, hydrogen consumption does not include the portion produced<br />

by the factory itself, because we believe that the product<br />

purchased on the market has greater impact on the environment.<br />

To this end, we must point out that over the last few years, chlorosilanes<br />

have not been used only to produce polycrystals. Some<br />

of this material is also used to produce the precious mixtures that<br />

are employed to grow expitaxial substrates.<br />

The consumption of diesel fuel increased in <strong>2009</strong> due to the<br />

need to heat a new engineering workshop and a new warehouse<br />

for reserve stocks of materials.<br />

The increase in consumption of potash, on the other hand, was<br />

caused by a greater level of hydrogenation that, in turn, was associated<br />

with the production of polycrystal.<br />

Decreased monocrystal production and a simultaneous increase<br />

in silicon production for the photovoltaic solar market (which<br />

requires different monitoring procedures that use less reagents<br />

as compared with the amounts needed for producing silicon for<br />

the microelectronic market) are the reasons behind the reduced<br />

consumption of hydrofluoric acid, nitric acid, acid mixtures and<br />

chromium trioxide.<br />

With regard to the consumption of Freon, a ban on the use of<br />

virgin HCFCs for the maintenance and repair of equipment went<br />

into effect on January 1, 2010. Thus, as much Freon as possible<br />

was loaded from warehouse stocks into the system last December.<br />

Greenhouse gas emissions are monitored by MEMC voluntarily.<br />

In fact, the factory is not included in the field of application<br />

of European Parliament and Council Directive 2003/87/EC,<br />

which implemented a system to trade greenhouse gas emissions<br />

within the European Union. Among other obligations, it requires<br />

obtaining authorization to emit greenhouse gases and mandates<br />

monitoring of emissions over time, with certification of the results<br />

of the monitoring by an accredited body.<br />

MEMC has identified its greenhouse gas sources as the combustion<br />

of fossil fuels (diesel fuel, fuel oil and natural gas) and the<br />

emission of refrigerant gases (R22 and R23).<br />

Combustion generates carbon dioxide (CO2), which is the main<br />

gas causing the greenhouse effect. The quantity of CO2 emitted<br />

by MEMC in <strong>Merano</strong> is estimated by multiplying the consumption<br />

of combustibles by the following conversion factors:<br />

• Between 2000 – 2006, the factors indicated in the CIPE<br />

(Italian Interministerial Economic Planning Committee) Resolution<br />

dated 25th February 1994 entitled “Approval of a National Program<br />

to reduce carbon dioxide emissions by 2000 to the levels<br />

in 1990” are as follows:<br />

• Diesel fuel 1 TOE = 3.10 t CO 2<br />

• Fuel oil 1 TOE = 3.07 t CO 2<br />

• Natural gas 1 TOE = 2.35 t CO 2<br />

• Since 2007, the factors indicated in Italian Directorial Decree<br />

no. Dec/Ras/854/05 dated 1 July 2005 promulgated by the<br />

Italian Ministry for the Environment and Territory and by the Italian<br />

Ministry of Productive Activities have been as follows:<br />

• Diesel fuel 1 ton = 3.173 t CO 2<br />

• Fuel oil 1 ton = 3.21 t CO 2<br />

• Natural gas 1 Std m3= 1.966 t CO 2<br />

• In <strong>2009</strong>, the factors indicated in Resolution no. 14/<strong>2009</strong><br />

from the Italian Ministry for the Environment and for Territorial Protection<br />

and by the Italian Ministry of Productive Activities, regarding<br />

notification of greenhouse gas emissions pursuant to Directive<br />

2003/87/EC, which updated the coefficients contained in the<br />

Directorial Decree cited above, were as follows<br />

• Diesel fuel 1 ton = 3.173 t CO 2<br />

• Fuel oil 1 ton = 3.16 t CO 2<br />

• Natural gas 1 Std m3= 1.957 t CO 2<br />

As for refrigerant gases, a calculation was made of emissions in<br />

terms of “carbon dioxide equivalent” by multiplying the consumption<br />

of gas by the following GWP (Global Warming Potential):<br />

• R22 (CHClF2 chlorodifluoromethane): GWP (100 years) =<br />

1500 (source: IFC Inc USA si GHG Protocol Initiative)<br />

• R23 (CHF3 trifluoromethane): GWP (100 years) =<br />

11700 (source: IPCC Second Assessment Report, 1996)<br />

The Global Warming Potential (GWP) represents the ratio between<br />

the warming caused by a gas over 100 years and the<br />

warming caused by the same quantity of carbon dioxide (CO2)<br />

during the same period. Therefore the value of carbon dioxide<br />

is one.<br />

It is noted that in <strong>2009</strong>, overall production of waste increased<br />

slightly due to an increase in the production of silicon and to<br />

The following table and graph show the production trends for<br />

hazardous waste alone, both in terms of absolute and<br />

specific amounts. As we have seen in previous <strong>Environmental</strong><br />

<strong>Statement</strong>s, hazardous waste is mostly generated during special<br />

maintenance operations closely tied to production trends, or in<br />

any case which were planned for periods exceeding one year.<br />

Specifically in <strong>2009</strong>, chlorosilanes were cleaned out of the depuration<br />

columns more frequently, maintenance operations were<br />

performed on the De Nora cells, and several pieces of equipment<br />

containing hazardous substances were sent out for disposal.<br />

The increase in waste output is mainly due to the start-up of large<br />

sites for the development of polycrystal production.<br />

In <strong>2009</strong>, reclamation operations generated 30,000 tons of soil,<br />

which were handled by an authorized treatment company so that<br />

they could be used as filler, pursuant to authorization by the Provincial<br />

Agency for the Environment of the Autonomous Province<br />

of Bolzano. The amount of filler was 14000 m3 (see also the<br />

chapter “Reclamation: Ensuring the Safety and Protection of the<br />

Soil and Groundwater”). This data was not combined with the<br />

quantity of waste shown in the table, so that a comparison can<br />

be made with previous years.<br />

Reclamation: Ensuring the<br />

Safety and Protection of Soil<br />

and Groundwater<br />

MEMC is strongly committed to protecting the soil and groundwater,<br />

and for some time has collaborated with professionals in<br />

this sector to reduce the toxic debt generated on-site by past<br />

operations. MEMC’s reclamation activities over the years, and<br />

monitoring activities currently in progress, were fully described in<br />

the 2004 and 2007 <strong>Environmental</strong> <strong>Statement</strong>s. See these <strong>Statement</strong>s<br />

for further information.<br />

Further contamination of the soil or groundwater is unlikely, given<br />

the equipment and the technical and supervisory measures now<br />

being taken.<br />

In <strong>2009</strong>, the selection and reclamation of soil excavated for our<br />

expansion project continued, in accordance with procedures<br />

contained in plans approved by the City of <strong>Merano</strong> and the Province<br />

of Bolzano. As occurred in the past, soil with contamination<br />

exceeding the thresholds allowed by law was sent to authorized<br />

disposal plants, and soil whose characteristics permitted its reuse<br />

were employed for the necessary filling inside the production facility.<br />

Groundwater barrier and monitoring operations are continuing<br />

as part of a project approved and authorized by the Provincial<br />

Agency for the Environment (Prot. no. 29.6/62.07.07/2593<br />

dated 13 May 2004).<br />

The authorization mandates annual monitoring. Therefore, we<br />

will continue monitoring our acoustic impact by taking annual<br />

measurements based on our internal monitoring program, barring<br />

significant process changes or justified requests by those<br />

involved.<br />

This is also in response to the results of the last monitoring operation<br />

performed from October to November <strong>2009</strong>, which was<br />

carried out by an expert who is a member of the provincial register<br />

ENVIRONMENTAL STATEMENT <strong>2009</strong><br />

INDIRECT ENVIRONMENTAL ASPECTS<br />

The indirect environmental aspects that MEMC regards as important<br />

are:<br />

• managing relations with suppliers offering materials or<br />

services that are critical to the environment and to safety;<br />

• the activities of third parties operating on-site;<br />

• the purchase and transport of hazardous goods;<br />

• communication activities.<br />

Managing Relations with Critical<br />

Suppliers<br />

The selection of critical suppliers is made on the basis of specific<br />

technical, economic, qualitative and environmental criteria.<br />

These criteria are assessed by a suitable company committee<br />

based on MEMC’s vendor rating procedure before orders are<br />

assigned and, subsequently, at regular periodic intervals. Part<br />

of this evaluation process is based on the evidence provided<br />

by the candidates concerning the precautions they take to protect<br />

the environment: This may include EMAS registration, or ISO<br />

14001 certification, for example. In their absence, the adoption<br />

of specific operational or procedural precautions is considered<br />

favourably. This applies especially when evaluating small or very<br />

small local companies typical of the Alto Adige business system<br />

that collaborate with MEMC in particular for maintenance work,<br />

as described in the next section.<br />

Suppliers of waste management services (those enterprises involved<br />

in the collection, transport, recycling and disposal of the<br />

waste produced by MEMC) are subjected to further checks. In<br />

fact, all mandatory documents are checked in order to confirm<br />

the adequacy and completeness of legal authorizations to carry<br />

out the activities, and the operating site is inspected.<br />

In particular, the Isolazioni Termiche di Agosti Romano company,<br />

in <strong>2009</strong>, offered innovative materials and solutions - with low<br />

environmental impact - for thermally insulating the plant systems at<br />

the factory. These included lighter, less bulky heat shields which<br />

can be replaced quickly in case of leaks and are reusable so they<br />

do not require disposal.<br />

Activities of Companies Operating<br />

On-site<br />

Other companies in charge of maintenance activities regularly<br />

operate on the factory site. These activities include building and<br />

insulation work, painting and electrical installation, as well as<br />

cleaning and canteen services. The expansion project currently<br />

underway has resulted in additional companies working on-site.<br />

MEMC operates in a number of ways when handling relations<br />

with these companies. All third parties operating on-site are informed<br />

of the existing risks in the factory and of the behaviour<br />

that is required in order to carry out their tasks safely and with<br />

respect for the environment. They are also informed of MEMC’s<br />

<strong>Environmental</strong> Policy and of the requirements of the environmental<br />

management system that concern them.<br />

Likewise, in order to organize the work well and maintain an<br />

adequate level of housekeeping, MEMC has selected and<br />

marked out suitable areas where each company can deposit<br />

its materials and waste. Where necessary, these areas are<br />

equipped with waste collection tanks to prevent contaminating<br />

the soil and underground water.<br />

MEMC’s vigilant surveillance procedures include periodic audits<br />

aimed to ensure compliance with its instructions and to maintain<br />

control over the substances used and the waste materials produced.<br />

Purchase and Transport of Hazardous<br />

Substances and Preparations<br />

Before new chemicals and preparations are introduced into the<br />

factory, including those from external companies, they must have<br />

the joint approval from management's representative for the protection<br />

of the environment and the competent doctor, who assess<br />

their hazardous characteristics as a function of various parameters,<br />

including their intended use, the nature of the processes<br />

involved, the presence of other hazardous substances, the type<br />

of exposure, etc. This assessment is made according to the provisions<br />

set out in MEMC’s specific management procedure.<br />

The goods are mostly transported by road, mainly because of<br />

geographic and infrastructural conditions which impede the use<br />

of rail or sea transport.<br />

Nevertheless, MEMC pays particular attention to this aspect.<br />

Qualified personnel check the documents and the vehicles involved,<br />

which are subject to ADR regulations (Carriage of Dangerous<br />

Goods by Road). TET and TCS are at present transported<br />

by rail as far as the <strong>Merano</strong> train station, and then by road<br />

to MEMC. Particular procedures have been adopted for some<br />

time to monitor the railway wagons and road vehicles used to<br />

transport the tanks of chemicals from the railway station to the<br />

factory. The road vehicles are preceded by a technical escort<br />

and a private security company guards the tanks of chemicals at<br />

the <strong>Merano</strong> train station.<br />

ENVIRONMENTAL STATEMENT <strong>2009</strong><br />

INDIRECT ENVIRONMENTAL ASPECTS<br />

Communications<br />

Communication is another important tool for relating to the<br />

outside world, which MEMC employs to underline its commitment<br />

to the environment and increase the interest of its numerous internal<br />

and external partners in this issue, to demonstrate its serious<br />

and constant commitment to environmental protection and - last<br />

but not least - remind people of the rootedness of the factory and<br />

the important social role it has always played in the local area.<br />

In this respect, during <strong>2009</strong>:<br />

• A project was launched in the schools in the province for<br />

studying alternative sources of energy, to provide an active contribution<br />

to promulgating a culture of sustainable energy and a<br />

sustainable environment - a field in which Alto Adige is undoubtedly<br />

on the cutting edge in Italy.<br />

• MEMC contributed to the creation of a book entitled “Sinigo.<br />

Con i piedi nell’acqua. Storia di un insediamento italiano<br />

nell’Alto Adige degli anni Venti” (“Sinigo. With feet in the water.<br />

The story of an Italian settlement in Alto Adige in the 1920s”)<br />

by Paolo Valente, published by Alphabeta Verlag, as part of an<br />

historical research project of the City of <strong>Merano</strong>. The book was<br />

sponsored by the City itself.<br />

governments, the SASA transit company in <strong>Merano</strong>), as well as<br />

opportunities that can be implemented directly by the company.<br />

The work that was done and the proposals that were made are<br />

summed up in a “Plan for Home-Job Commuting” that has been<br />

provided over the company’s Intranet to all personnel.<br />

• training and environmental awareness-raising continued to be<br />

given to employees, according to plans set forth in <strong>Environmental</strong><br />

Training and Internal Communication programs;<br />

• a digital copy of the validated 2008 <strong>Environmental</strong> <strong>Statement</strong><br />

was made available to all those involved - in printed form<br />

and on CD-ROM - and was also published on MEMC's website<br />

(www.memc.com).<br />

It should be noted that in response to these projects, the Province<br />

of Bolzano - in a letter dated February 3, 2010 from Christian<br />

Tomasini, the Vice-President of the Province - praised MEMC for<br />

“...its enormous commitment to the ongoing development of new<br />

technologies and processes that pay increasing attention to the<br />

environment, and to the company’s relations with the local area”.<br />

• In <strong>2009</strong>, in cooperation with the Mobility Manager of the<br />

City of <strong>Merano</strong>, a project was begun that is intended to optimize<br />

commuting from home to job by MEMC personnel. The goal is to<br />

provide an active contribution to an effort to reduce traffic, which<br />

was launched by the City and by the Province.<br />

The project has been developed in multiple phases:<br />

• raising the awareness of personnel regarding the theme of<br />

mobility<br />

• a preliminary evaluation whose purpose is to “get to know”<br />

the company’s personnel from the standpoint of mobility, with particular<br />

emphasis on current habits and behaviour, limitations (such<br />

as place of origin, work schedules), needs (such as family responsibilities)<br />

and opportunities (for example, grouping together<br />

personnel in the local area who have similar work schedules and<br />

take the same routes from and to the factory)<br />

• an analysis of the means available for travelling from and<br />

to the factory, with special importance given to public transit<br />

• identification of opportunities for improvement that will be<br />

proposed to local public agencies (the municipal and provincial<br />
