  8. Voting Results on ISO 14855-2（Gravimetric measurement of carbon dioxide evolved in a laboratory-scale ） • P-Members voting in approval=18=100% (2/3=66.7% requires) • P-Members voting negative=zero • Comments from France and Germany should be considered at the next revision if required. • The ballot has been APPROVED. • ISO 14855-2 was published on Aug. 28, 2007.

  9. Ｓｙｓｔｅｍａｔｉｃ　Ｒｅｖｉｅｗ • ISO16929 (Disintegration in a pilot scale test) • A simple majority of the P-members propose confirmation: 13 p-members among 20. • This standard has been adopted unchanged for national use in four countries: UK, Japan, Netherlands and Italy. • Comments are from Japan (purely editorial) and Germany (somewhat technical)

  10. German comment related to validity. • Maximum allowable difference of the degree of disintegration should be provided. • Action Plans 1:

  11. ISO 15985 (Anaerobic biodegradation under high-solids anaerobic-digestion conditions) • A simple majority of P-members propose confirmation: 12 p-members among 20. • This standard has been adopted unchanged for national use in five countries: UK, Japan, Malaysia, Netherlands and Italy. • Technical corrigendum published related to Japanese comments.

  12. ISO 15985 TECHNICAL CORRIGENDUM 1Published 2007-11-15 • Page 6 • In Subclause 9.2, second line from the end of the subclause, replace σM by σ so that the line reads: • σ is the standard deviation of the total amount of carbon dioxide produced. • Page 9 • In Annex B, line 7, replace “Thus, the mass loss • from replicate i (%)” by “bi” so that the line reads: • biis given by

  13. ISO 20200 (Disintegration in a laboratory-scale test) • A simple majority of P-members propose confirmation: 12 p-members among 20. • This standard has been adopted unchanged for national use in ten countries: UK, Japan, Netherlands, France, Spain, Hungary, Cｚech, Switzerland, Finland and Italy. • Only one comment will be German technical comment just alike ISO16929.

  14. German comment related to validity. • Maximum allowable difference of the degree of disintegration should be 20％. • Action Plans 2:

  15. NWIP (Preparation of test and reference materials) • The vote was positive with 12 positive votes, without negative votes. • A simple majority of the P-members approved the NWIP. • Six P-members , Sweden, Germany, India, Japan, Italy and Switzerland would like to participate in this project. • The NWIP was approved with more than 2/3 positive votes together with 6 p-members participations (more than 5). • Comments were received from 4 countries: Germany, India , Switzerland and Italy.

  16. Discussion on NWIP • NWI is only about the preparationroute and not specific materials. • Title was changed to “Preparation of samples for biodegradation test of plastics material.” • Comments and observations on NWIP were discussed, and all appropriate comments will be incorporated into the text by Dr. Kunioka. • Action Plans: 3

  17. FDIS 17088(Specification for compostable plastics） • FDIS17088 was not distributed for FDIS ballot at Goa meeting. • No further actions were required at this meeting. • After WG22 in Goa, FDIS 17088 was distributed for the 2-month ballot on Nov. 29, 2007. Voting terminates on Jan. 29. 2008. • We have not received the results of the FDIS ballot.

  19. Action Plans (I) • Based on thorough discussion of WG22 meeting in Goa,the following actions are needed.ACTION 1: ISO 16929(Disintegration in a pilot scale test) • Mr. De Wilde (Belgium) and Dr. Walling (USA) should provide a review for revision of ISO 16929.  If necessary, the report should be supplied at the next meeting.  So, necessary comments should be supplied by WG22 members to Mr. De Wilde and Dr. Walling as the need raises.

  20. German Comments • ISO 16929 provided no information on allowable difference of the degree of disintegration. • ISO 20200 provided 10％ allowable difference. • Germany proposed that allowable difference of the degree of disintegration for the three replicates shall not differ by more than 20 %.

  21. Action Plans （II) • ACTION 2: ISO 20200(Disintegration in a laboratory-scale test) • Dr. Degli Innocenti (Italy), Dr. Walling and Mr. De Wilde should present a report for the next meeting presenting data to justify the change from 10 to 20%.  If necessary, Dr. Degli Innocenti (Italy), Dr. Walling and Mr. De Wilde should present a report for the next meeting presenting data to justify this change.Action 3: WD 10210(Preparation of samples for biodegradation test of plastics Material) • Dr. Kunioka (Japan) should distribute a second draft to WG22 member by January 15, 2008.  Without any critical comments this draft will advance to CD.

  22. Contents • Introduction • Overview • Action Plans • Future projects Home-composting Bioplastics- Renewable Material 5. Summary

  23. Possible future new work items • It was agreed to put a hold on the following two items. Dr. Narayan proposed that he discussed these items further with interested parties and report back. • “Specification for inherent biodegradability of biodegradable plastics” • “Specification for colorants to be used with biodegradable plastics”

  24. Home Composting (I) • Swedish proposal: Dr. Jakubowicz • Thermophilic phase (45～65℃）+ mesophilic phase (20～40℃） • Solid matrix: Based on ISO 14855mature compost or a mixture of mature compost and vermiculite • (Mainly Disintegration) Basically based on ISO 20200 • Thermophilic phase: most pathogens will be destroyed above 55 ℃ and weed seeds and fly larvae killed above 60 ℃.

  25. Home Composting(II) • Italian proposal（UNI 11183) • Dr. Degli Innocenti • Mesophilic phase（Ambient temperature) • 10℃～45℃ fertile soil • Biodegradation and ecotoxicity without disintegration • ISO 17556, 14851, 14852 (365 days, 21-28 ℃） • Home composting will be debated further in the future meeting.

  27. ISO 14021 Environmental labels and declarations - (Type II environmental labelling) • According to ISO 14021, there are two options to the composting. One is a home-composting facility, the other is an on-site or central composting facility. • Definition of home-composting

  28. ISO 15270 (ISO/TC61/WG2)Guidance on environmental provisions in plastics standards 1. Material recovery • Mechanical recycling • Chemical recycling • Biological recycling (composting) 2. Energy recovery • Usable heat under controlled combustion conditions

  31. Ｌｉｓｔｓ　of ISO standards (1) • All the standards of ISO/TC61/SC5/WG22 contribute to sustainable development, especially in an ecological viewpoint. • 1) ISO 14851 Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium – Method by measuring the oxygen demand in a closed respirometer • 2) ISO 14852 Determination of the ultimate aerobic biodegradability of plastic materials in an aqueous medium – Method by analysis of evolved carbon dioxide • 3) ISO 14853 Determination of the ultimate anaerobic biodegradability in an aqueous system – Method by measurement of biogas production • 4) ISO14855-1 Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions – Method by analysis of evolved carbon dioxide Part 1 General Method

  32. Ｌｉｓｔｓ　of ISO standards (2) • 5) ISO 14855-2 Determination of the ultimate aerobic biodegradability of plastic materials under controlled composting conditions Part 2 Gravimetric measurement of carbon dioxide evolved in a laboratory-scale test • 6) ISO 15985 Determination of the ultimate anaerobic biodegradability and disintegration under high-solids anaerobic-digestion conditions – Method by analysis of released biogas • 7) ISO 16929 Determination of the disintegration of plastic materials under defined composing conditions in a pilot-scale test • 8) ISO 17556 Determination of the ultimate aerobic biodegradability in soil by measuring the oxygen demand in a respirometer or the amount of carbon dioxide evolved • 9) ISO 20200 Determination of the degree of disintegration of plastic materials under simulated composting conditions in a laboratory-scale test.

  33. Biotechnology Ⅱ Bioplastcs Bioplastics are derived from renewable resources such as biomass and agricultural products. Bioplastics are considered as biodegradable. ISO/TC61/SC5/WG22 discussed possible definitions such as biopolymer, biobased plastics, bioplastics and biomass plastics at SC5/WG22 meeting in Goa. This issue will be considered as high priority in the future SC5/WG22 meeting.
