Results of Eco-Efficiency
Analysis showed that
diversion of organic waste
from landfills to composting
results in lower environmental
impacts and has better total
economic value.
Eco-Efficiency Analysis
Evaluates both environmental impacts and total cost

répercussions environnementales et le coût total

Source Separated Collection of Organic Waste Makes Sense
La collecte sélective de déchets organiques, c’est logique
Composting
Source: ROUGH calculations by BASF not third party verified
System boundaries: A person uses a bag to collect 1 kg of organic kitchen waste. If PE bag is used, both waste and the bag are disposed off in landfill or incineration
plant; if ecovio bag is used, organic waste is composted together with the bag.
Assumptions: Incineration of organic kitchen waste is assumed to be without energy recovery (heating value is 3,6 MJ/kg, accepted from the Critical Review Panel on the
EEA study of “2 in 1” bag). Energy recovery by incineration of the PE bag is included but of no relevance. In the composting scenario, it is assumed that fertilizers are
substituted.
Results range: 10% uncertainty

Certified Compostable products act as carrying media for organic
waste and increase diversion, but there are still some barriers to
their acceptance, education and guidelines are needed.
Les produits compostables certifiés agissent comme support
porteur pour les déchets organiques et augmentent le
détournement, mais il y a encore quelques obstacles à leur
acceptation; de l'éducation et des lignes directrices sont requises.
• Confusion between Bio-degradable and Compostable
• Confusion between Bio-based and Compostable
• What is a certified compostable product?
• Would they compost in my facility?
• Can’t differentiate them from non-compostable

Glossary:
Glossaire:
10
Biodegradable (Oxford dictionary): Capable of being decomposed by bacteria or
other living organisms.
Biodegradation (Recyc-Québec): Degradation caused by biological activity, in
particular by enzymatic action causing a significant change in the chemical
structure of a material (BNQ 9011-911 / 2007)
Compostable (Recyc-Québec): Which biodegrades under the action of
microorganisms and is certified according to recognized standards on
compostable products including the Canadian standard CAN / BNQ 0017-088.
Biodégradable (Oxford dictionary): Capable d'être décomposé par des
bactéries ou d'autres organismes vivants.
Biodégradation (Recyc-Québec): Dégradation causée par une activité
biologique, en particulier par une action enzymatique entraînant une modification
significative de la structure chimique d’un matériau (BNQ 9011-911/2007)
Compostable (Recyc-Québec): Qui se biodégrade sous l’action des
microorganismes et qui est certifié selon les normes reconnues sur les produits
compostables, dont la norme canadienne CAN/BNQ 0017-088

150 years
Certified compostable products:
Produits compostables certifiés:
• Comply to Canadian BNQ (CAN/BNQ 0017-088) and ASTM 6400
Specifications for Certified Compostable Bags and Products
• Biodegrade in aerobic industrial composting process, such is not readily
distinguishable from the other organic materials in the finished compost.
• Have no adverse effect on the ability of the compost to support plant
growth.
• After 84 days no more than 10% of the original dry mass remains after
passing through a 2.0 mm sieve

Would they compost in my facility?
Seront-ils compostables dans mon site?

TEST them (example Ref. BioCycle June 2015, p 51 Cedar Grove):
Certified Compostable products biodegrade in Aerobic composting
process; (windrow, static pile, open and enclosed, etc.) and convert
into CO2, biomass, water. Rate would depend on length and
conditions of the active phase Note: inquire with the Certified Compostable
Committee (CCC & MWA) if any test has been done.
Aerobic*: When living organisms that use oxygen feed upon organic matter,
organic material decomposing with oxygen is an "aerobic" process. Carbon
serves as a source of energy for organisms and is burned up and respired as
carbon dioxide (CO2).
*Ref. Whasington State University, whatcom county extension

TEST them cont, certified compostable products:
Do not disturb Dry Anaerobic Digestion process as they biodegrade
at the digestate aerobic composting stage. Note: inquire with the Certified
Compostable Committee (CCC & MWA) if any test has been done.
Anaerobic*: Composting without oxygen results in fermentation. This causes
organic compounds to break down by the action of living anaerobic organisms.
Carbon from organic compounds is released mainly as methane gas (CH4).
Intensive reduction of organic matter by putrefaction is usually accompanied by
unpleasant odors.

au Canada
Joint study with large Canadian DRY AD/Composter
with >3 MM population
Testing of plastic contamination from…
Post AD, Feedstock, Overs, Finished product, turned windrows
Reference PBAT, PHA samples provided by BASF
~ 50 samples collected by site management and tested by
independent laboratory to identify the plastic material
Results (2 reference samples)
PE, PBAT found in Post AD sampling (2 samples)
PE, PBAT found in feedstock samples (7)
PE, PP found in Overs samples (14)
PE, PP found in finished product samples (12)
PE found in turned windrow samples (12)

Outcome – no compostable material found at end of composting process despite being present at the input.

“Can’t differentiate them from other bags”
Action & Collaboration needed from Stakeholders
«On ne peut pas les différencier des autres sacs»
Action et collaboration nécessaires des parties prenantes
18
Suggested differentiation for certified compostable bags
• Translucent clear or greenish tint bag to allow content to
be seen through
• With Prominent BNQ &/or BPI certification logo, (or
repeated BNQ&/or BPI logos) for easy recognition &
differentiation by consumers, haulers, composters.

«On ne peut pas les différencier des autres»
Action et collaboration nécessaires des parties prenantes
Working group, Certified Compostable Committee
(CCC+MWA) on guidelines on labelling and differentiation
of certified compostable products vs. non-certified
Would need regulation reinforcement on unsubstantiated
biodegradable claims according to National Standard of
