Cradle to Cradle Certification

Guy Van Marcke de Lummen AGC Glass Europe

2 AGC Glass Europe

Green product certifications: The choice

Labels: • Can be granted by NGOs,

public bodies or private companies

• Based on criteria defined by an ISO international standard

• Can take into account the life cycle of product

3 AGC Glass Europe

Green Product certifications: The choice

• Criteria used for the selection: – Global recognition – Length of labelling process – Application field: product – Rating system – Type of info to be provided + testing type – Know-how in the building sector

4 AGC Glass Europe

Cradle to Cradle: Principles

Take Make Waste

… and associated challenges: a world of limits

Growth in consumption of raw materials Resources depletion Surge in price of non-renewables Untapped resources in landfills

8 AGC Glass Europe

Cradle to Cradle: Principles

• The concept is broader than recycling and focuses not on reducing consumption but on sustainable development (eco-effectiveness)

• A concept in which waste and by-products act as raw materials for a new product

9 AGC Glass Europe

Cradle to Cradle: Principles

Creating a positive footprint through innovation.

Growth is good. “More of a good thing”

Eco-effectiveness

Waste equals food

Use current solar income

Celebrate diversity

10 AGC Glass Europe

Cradle to Cradle: Principles

• Products and processes are designed in such a way that materials remain available to humans and their natural environment.

• Products are designed so that the materials can be completely reused in the technical cycle.

• Products in the technical cycle must act as a high-quality raw material for new products in the technological domain.

• Absolutely no harmful waste substances may be released during the manufacturing process.

• Products are manufactured using sustainable energy sources.

• Continuous improvement required.

C2C in a Nutshell

11 AGC Glass Europe

Cradle to Cradle Certification: criteria

- Criteria on 5 topics •Material health •Material reutilization & carbon management •Renewable energy use •Water stewardship •Social responsibility

- Focus on product rather than on life cycle - Absolute pass or fail criteria and product rating - Emphasis on optimizing product design

12 AGC Glass Europe

Green Little to no risk associated with this substance. Preferred for use in its intended application

Yellow Low to moderate risk associated with this substance. Acceptable for continued use unless a GREEN alternative is available.

Red High hazard and risk associated with the use of this substance. Develop strategy for phase out

Grey Incomplete data. Cannot be characterized.

Banned As, Cd, CrVI, Hg, PVC, flame retardants, phtalates, etc.

Cradle to Cradle Certification: Criteria Example: Toxicity Ratings for Chemicals

• Deep chemistry inventory: – the product formulation of each product down to 0.01% must be

obtained. • Collect formulation information throughout the supply chain. • Ban of some substances above 0.1 %.

Cradle to Cradle Toxicity Ratings for Chemicals

13 AGC Glass Europe

Pass or fail criteria*

Material health

Material reutilization

Renewable energy use

Water Stewardship

Social Responsibility

Cradle to cradle toxicity ratings for chemicals - colour matrix

≥50% green assessed materials

no red assessed chemicals

thresholds for certain chemicals

Limit for Hg, Pb, Cd, CrVI

Material Reutilization Score = [( % Recyclable/Compostable Content X 2) + (% Recycled/Renewable Content X 1)] / 3

≥50 ≥65 ≥80

Strategic plan to supply that energy via current solar income

Energy amount for product manufacture/ assembly

50% renewable energy or through purchases of renewable energy certificates (RECs) and carbon offsets

≥50% of the entire energy footprint must be renewably powered

Water Stewardship Guidelines

Water audit for manufacturing facility

Implement innovative water conservation and water discharge measures.

Respecting diversity = one central principles of Cradle to Cradle. Manufacturers -> to practice business -> respects the health, safety, and rights of people and the planet.

Publication of corporate ethics or social performance goals

Third party social accreditation or certification The company must

complete a third party social responsibility certification.

Characterization of energy

Water audit for manufacturing facility

Intention to optimize product as Technical or Biological Nutrient product

Characterization of water

Characterization of business practices

Criteria 2012.

Why “Green” certification for Glass products ?

LCA is today considered as the best way to assess products, however:

– Do not fully address the presence of hazardous substances – Does not allow simple comparison of products i.e. no rating system – Do not give information on the environmental management in the

supply chain – Do not take into account energy & CO2 saved by the building during use

Carbon Footprint at Product level

•The product of 1 m² of low-e double glazing unit is responsible for the emission of 22 kg CO2 •Based on LCA

CO2 emissions CO2 avoided

•On the other hand, the CO2 saved by replacing one square metre of single glazing by low-e double glazing represents 91 kg CO2 per year. •The CO2 emitted during production is thus offset after only 3 – 10 months use. •Based on Carbon Footprint

The process of manufacturing flat glass for building applications inevitably has a cost in terms of CO2 emitted, but the emissions are by far offset due to the savings in use.
