South African Standard Grade Definitions For Recovered Paper (February 2009)

TERMS & DEFINITIONS

This list of South African Standard Grades of Recovered Paper and Board gives a general description of the standard grades by defining what they do and do not contain. It is recognised that specific deals between buyer and supplier for standard grades with special specifications will still be necessary to meet individual requirements. Collected paper segregated from refuse sorting stations is not suitable for use in the paper industry. It is recommended that the standard is used at all industry levels. It secures the quality of the recovered paper supply to the paper mills.

Out-throws: The term out-throws is defined as all papers that are so manufactured or treated or are in such a form as to be unsuitable for consumption as the grade specified.  

Prohibitive Materials: Anything which is not paper or paperboard and if included in the recovered paper may during processing cause damage to machines or interruptions to production. 

Specific examples include:  

  • Metal
  • Plastic
  • Glass 
  • Textiles 
  • Wood
  • Sand and building materials
  • Synthetic materials
  • Synthetic paper.

Moisture Content in Recovered Paper & Board 

Recovered paper and board will in principal be supplied with moisture of not more than the naturally occurring level - where the moisture content is higher than 10% on paper and 12% on kraft/board (of air dried weight), the additional weight in excess of the allowed percentage may be claimed back.

Method of Testing & Sampling 

The equipment to be used for testing is either:

  • Emco AP 500 hand gauge (or equipment with similar specifications).
  • Oven dry method.
  • Aquabouy

In both cases a random representative sample will be taken and subject to testing by one or other of the above methods as agreed between buyer and seller. When new or advanced technology becomes available these procedures may change and will be communicated by way of revised schedule.
