Sustainable Use of Resources and Energy

SCHOTT Flat Glass is dedicated to protecting the environment and particularly in optimizing the use of resources in production. We strive to optimize and arrange our manufacturing processes in such a way, that they require a minimal amount of raw materials and energy. In recent years, various programs that form the basis for technical change have been implemented to systematically monitor our consumption levels of resources and energy.

Our focus areas are:

photovoltaic cells

Electricity consumption

SCHOTT Flat Glass aims to pursue a highly energy-efficient production. Therefore we routinely conduct energy screenings or energy audits. These provide a first overview of our energy consumption and highlight potentials for improvement. Some examples of measures that we established are:
  • Increasing energy consumption awareness among our employees
  • Establishing energy load management
  • Optimization of furnace loads
  • Usage of low-energy production equipment

Renewable Energy at SCHOTT Flat Glass

SCHOTT continues to systematically extend its ecological commitment by introducing environment-friendly technologies. One example for SCHOTT’s ecological thinking includes the consumption of solar energy.
SCHOTT Flat Glass established this renewable energy source by installing a photovoltaic plant on the rooftop of the SCHOTT Italvetro production site in Borgo a Mozzano, Italy, in January 2012. It can generate approximately 780,000 kWp of green electricity annually with the help of 851 modules from SCHOTT Solar. The energy produced is used for the manufacturing processes.
water consumption

Water consumption

Water is mainly used in the production process to cool and to cut glass. We carefully steer our processes to minimize the consumption of water. Audits are regularly conducted in the factories to control the consumption of water and identify potentials for reduction. The following examples are just some of the measures that have been implemented in recent years:
  • Control of the pipeline network to reduce water leakage
  • Optimization of machines to reduce splashing water
  • Implementation of closed water circuits in several of our plants
The measure that has had the greatest impact on the reduction of water consumption has been achieved by the introduction of closed water systems.
Waste management and glass recycling

Waste management and glass recycling

As in every manufacturing process we generate a certain amount of waste. For many years we have carefully been taking opportunities to reduce waste generation and differentiate between two main categories: non-hazardous waste and hazardous waste.

Non-hazardous waste

The main waste which is generated during our manufacturing processes is glass waste. We pursue two objectives: reducing glass waste in production and increasing our glass recycling rate. An important area for glass waste reduction is our cutting process. For many years we have been optimizing the cutting glass with computer-assisted processes. In addition all other processes are systematically checked to reduce the waste of glass.

Hazardous waste

The rate of hazardous waste compared to other waste is minimal, approximately 1.5 to 3 percent. We are continuously searching to substitute and reduce any hazardous material that we use in our manufacturing processes.

Waste glass recycling

One of the main benefits of glass is that it is “infinitely recyclable.” Depending on the glass type, up to 95 percent of the glass waste within our plants is recycled into the production of new glass. Glass scraps are sorted and separated according to their composition; for example, printed glasses and non-printed glass. The glass is then returned and recycled to be melted again for flat glass production or for the manufacture of glass bottles as well as for insulation materials in the construction industry.
Heavy metal-free paints

Heavy metal-free paints

Environmental compatibility is a determining factor when we select materials, technologies and production methods. As a manufacturer of decorated flat glass, paint is one of the major materials used in our products. Standard paints often contain solvents, binders, preservatives and additives composed of heavy metals. Whenever possible, we have substituted heavy metal-containing paint with heavy metal-free paint for the manufacture of our products. More than 90 percent of our paint consumption is today free from heavy metals, even though this is not mandatory for all applications of our products. Our goal is to achieve a 100 percent use of environment-friendly paint.
Heavy metal-free paints
RoHS compliance

RoHS and REACH compliance

SCHOTT follows the EU directive 2002/95/EC “RoHS” on the restriction of the use of certain hazardous substances in electrical and electronic equipment. SCHOTT also assumes responsibility for the environment as part of the EU regulation REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) that governs chemical substances. SCHOTT ensures that all of the products that the group produces comply with today’s legislative requirements as well as requirements expected in the future.
