BASIC CRITERIA FOR THE AWARD OF THE ENVIRONMENTAL LABEL
Recycled Gypsum Products RAL-UZ 60

1 Preliminary Remarks:

1.1
In cooperation with the Federal Minister for the Environment, Nature Conservation and Nuclear Safety, the Federal Environmental Agency and considering the results of the expert hearings conducted by RAL, the Environmental Label Jury has set up these Basic Criteria for the Award of the Environmental Label.
RAL, reg. assoc., has been entrusted with the award of the Environmental Label.
Upon application to RAL and on the basis of a Contract on the Use of the Environmental Label to be concluded with RAL the permission to use the Environmental Label may be granted for all products, provided that they comply with the requirements as specified hereinafter.

1.2
Flue gas desulphurization of fossil-fuel power plants produces an annual amount of some million tons of gypsum which can be recycled or must be disposed of as waste.
The same applies to gypsum resulting from the manufacture of various chemical products. The high quality and saveness of these gypsums justify their use for the production of building materials and hence the substitution of normally used natural gypsum. As a result, scarce landfill space and natural resources can be saved.
The increased use of waste paper, especially low and medium-grade papers, and the use of small and waste timber also helps to ease the environmental burden.
Award of the Environmental Label to gypsum wallboards, gypsum fibreboards and gypsum chipboards is to promote gypsum recycling and the use of waste paper and waste timber.



2 Scope
These Basic Criteria apply to gypsum wallboards pursuant to DIN 18180, as amended, gypsum fibreboards and gypsum chipboards for interior works.
Gypsum wallboards predominantly consist of gypsum. Their flat surfaces and longitudinal edges are covered with adhesive board depending on the intended use.
Gypsum fibreboards mainly consist of gypsum mixed with paper-making fibres.
Gypsum chipboards mainly consist of gypsum mixed with wood chips.



3 Requirements

3.1 Gypsum used for product manufacture must be industrial residues coming - at 100 per cent - from flue gas desulphurization plants or other production processes.

3.1.1
With regard to their characteristic radioactive radiation the gypsum used must meet the requirements of the Leningrad Formula:

CK
 
CRa
 
CTh
 
_________
 +
_________
+
_________
≤ 1
130pCi/g
 
10pCi/g
 
7pCi/g
 

3.2
The fibre content of paper used for the production must be at 100 per cent (tolerance: 5%) from low-grade, medium-grade and kraft-containing waste paper (CategoriesI, II, IV - except for W 13 and W 41 - and V of the List of German Standard Grades, Appendix 1 of the Basic Criteria to RAL-UZ 60).

3.3
Wood chips used in gypsum chipboards must come at 100 per cent (tolerance 5%) from waste timber, small timber or wood residues which have not been treated with wood preservatives.

3.4
The products under para. 2 may contain ingredients requiring marking according to "Gefahrstoffverordung" (Ordinance on Hazardous Substances), as amended, only if their content does not exceed 50% of the limit concentration, as specified in Annex I to Nos. 2.1 and 2.2, Ordinance on Hazardous Substances.

3.5
Building materials subject to approval under construction laws must be equipped with the respective approvals.

3.6
Building materials not being subject to approval under construction laws must meet the pertinent serviceability and safety requirements, e.g. with regard to compressive strength, loading capacity, humidity and fire behaviour (gypsum wallboards according to DIN 18180).



4 Compliance Verifications

4.1
The applicant shall declare compliance with the requirements under paras. 3.1 to 3.4. The constituents of products under para. 2 are to be given in weight per cent.
The applicant shall indicate the origin of the gypsum used and its characteristic radioactive radiation according to the Leningrad formula. Safety Data Sheets pursuant to 91/155/EWG are to be presented for additives (except for gypsum, paper and wood).
The applicant shall state in writing that the wood chips made from waste timber, small timber or wood residues have not been treated with wood preservatives.
In addition, the manufacturer shall send annual reports to the Umweltbundesamt (Federal Environmental Agency) by December 31 of each year listing quantities and origins of the gypsum used, quantities of recycled board and/or recycled paper and wood used for the products marked with the Environmental Label.

4.2
Certificates of approval are to be presented for building materials according to para. 3.5, while technical data sheets regarding the serviceability and safety requirements are to be presented for building materials according to para. 3.6.

4.3
The applicant shall present product description and advertising brochures.



5 Applicants and Parties Involved

5.1
Applications may be filed by manufacturers of products according to para. 2.

5.2
The following parties are involved in the award procedure:
RAL, Umweltbundesamt (Federal Environmental Agency) and the Federal State where the production plant is located that manufactures the products to be marked with the Environmental Label.



6 Use of the Environmental Label

6.1
The terms governing applicant's use of the Environmental Label shown on page 1 are stipulated by a Contract on the Use of the Environmental Label to be concluded with RAL.

6.2
Within the scope of such contract the applicant under-takes to comply with the requirements as specified inpara. 3 as long as he makes use of the Environmental Label.

6.3
Contracts on the Use of the Environmental Label are concluded for the marking of products according to para. 2.
These contracts shall run until December 31, 2004. They shall be extended by periods of one year each, unless the contract is terminated in writing by March 31, 2004 or by March 31 of the respective year of extension.
After the expiry of the contract the Environmental Label may neither be used for labelling nor for advertising purposes. This regulation shall not affect the products being still in the market.

6.4
The applicant (manufacturer) shall be entitled to apply to RAL for an extension of the right to use the label to the product entitled to the label if it is to be marketed under another brand/trade name and/or under other marketing organizations.

6.5
The Contract on the Use of the Environmental Label shall give the following particulars:

6.5.1
Applicant (manufacturer)

6.5.2
Brand/trade name, product designation

6.5.3
Distributor (label user) i.e. the marketing organization according to para. 6.4
