I could also send it on ResearchGate.<br /><br />This specific claim "Based on the assumption that landfills collect 75% of the generated gas, the EPA GHG Inventory4 estimates that 69% of landfilled waste was disposed in landfills with gas collection (flared or converted to energy) and 50% of that waste was disposed in landfills with energy recovery."<br /><br />Came from the 2010 US EPA GHG Inventory<br />Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990 2008, EPA 430-R-10-006; U.S. EPA: Washington, DC, 2010.<br /><br />Which can be found here: https://www.epa.gov/ghgemissions/us-greenhouse-gas-inventory-report-archive<br /><br />The latest (2016) version can be found here: https://www.epa.gov/ghgemissions/us-greenhouse-gas-inventory-report-1990-2014<br /><br />Let me know if you need anything else.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-8886930970819075598.post-46399671807161904572016-08-23T14:03:38.782-07:002016-08-23T14:03:38.782-07:00Jim - can you provide the source document for this...Jim - can you provide the source document for this statement?<br />The EPA estimates that 69% of waste is in landfills that collect methane. <br />I need this desperately.<br />Thanks<br />Tom OwensAnonymoushttps://www.blogger.com/profile/01030322098826157692noreply@blogger.comtag:blogger.com,1999:blog-8886930970819075598.post-71823166120515240902013-05-09T20:16:46.122-07:002013-05-09T20:16:46.122-07:00Interesting to say the least.

I have been traveling. <br />We would've loved to have directly modeled PLA in the study, unfortunately the necessary anaerobic degradation data is not publicly available. Full decay rate and methane potential tests are expensive and were not part of this study. We did address the benefits of biodegradability generally in the sensitivity analysis, though. It clearly shows that a decreased rate and extent of anaerobic degradability will lead to reduced GHG emissions, with completely recalcitrant materials leading to the least possible emissions. I hope that answered your question.Anonymoushttps://www.blogger.com/profile/13343513167422471726noreply@blogger.comtag:blogger.com,1999:blog-8886930970819075598.post-21172810229917484832011-08-04T02:21:51.814-07:002011-08-04T02:21:51.814-07:00Dear Jim,

I am a material chemistry Phd but some details of your study were quite hard to understand for a non-specialist like me.<br /><br />I have one question: Why did you use PHBO for your study ? I think I have a quite good knowledge of the bioplastic market and I've nerver heard anything about this material ... Why don't you use a commercial available one as PLA for example ?<br /><br />Thank you very much for your answer,<br /><br />Best Regards,<br /><br />AntoineAnonymousnoreply@blogger.com
