SUSTAINABILITY IN THE BORTOLOMIOL WINERY

Student: Marco Buso

Research of the last year of studyV ITIS – 2010/11

The CompanyBortolomiol winery is located in Valdobbiadene and produces wines and sparkling wines (Prosecco DOCG).

The company produces their own grapes, but also it buys grapes from other producers (always from Valdobbiadene), transforming them into a finished product.

Areas

The winery is divided into these areas:

- Sparkling (green)

- Product storage (red)

- Filling and packaging (blue)

- Offices

- Winery

- Vineyards

Consumption dataIn 2010 we took over energy consumption in every area of the Company.

Analyse of energy needs

We set an electronic spreadsheet to analyze the following energy needs:

Heating needs (offices, product storage, filling and packaging)

Cooling needs (winery and sparkling)

Electricity (offices, winery and sparkling)

Distribution of energy consumptionThanks to the energy analysis, we can draw the following graph, where we

can see how the energy needs are divided between the Company areas.

Distribution of energy consumption

Energy balanceBortolomiol winery began a process of conversion of its structure for

having a rational consumption of energy, for saving energy and for using

renewable sources.

A first step was done a few years ago with the signing of a contract with a

provider of electricity generated exclusively from renewable sources.

Electricity is the main form of energy

used by the company, so this choice

was very important in terms of

sustainability.

Environmental balanceWhen the carbon dioxide, produced (directly or indirectly) in the

various activities of the company, is the same of the carbon

dioxide absorbed by the company itself, the impact on

environment is balanced.

Usually the environmental balance is the following:

CO2 emissions and absorptions in vineyard

It is interesting to show the environmental balance in the vineyard,

where we calculated the emissions and removals of CO2 :

ConclusionsThe storage of the product is the activity with the higher energy consumption.

The analyze of data shows that there is a waste of energy: the heating produced by the condensers of the chiller is not used in any way.

This amount of energy can be easly used inside the winery.

We also notice that the company has a good environmental balance, but it is not the same the energy one. That’s why the company decided to install a PV system (that is working now with a production of about 50˙000 kWh per year).
