In Sweden, we had continuous growth of the households waste production for at least 20 years. However, this trend is broken since 2008, and the municipal waste production is reducing. The organization Swedish Waste Management (Avfall Sverige) has recently published the data for the total municipal wastes 2010, and their treatment methods, which shows a clear decrease compared to 2009 and 2008.

Now, Japan has changed their policy and wants to have solar energy for 10 million households in 2020. Let's see if this goal is too ambitious or not!

There is a better life index which include several factors as housing, income, jobs, community, educations, environment, governance, health, life satisfaction, safelty and work-life balance. It compares 34 OECD countries here, but I think they forgot to add happiness which is a major factor. Sweden has a good position in this index!

Our PhD candidate Azam Jeihanipour has worked now about 4 years on these wastes and developed processes for conversion of textile wastes to ethanol and biogas. She will defend her thesis in two weeks on 27 May 2011. I wish her success during the defense!
Her thesis can be found here, and her published articles the thesis:
1- Ethanol production from cottonbasedwaste textiles”, Bioresource Technology (2009), 100 (2), 1007-1010
2- Enhancement of ethanol and biogas production from high-crystalline cellulose by different modes of NMMO pretreatment”, Biotechnology and Bioengineering (2010), 105 (3), 469-476.
3- A novel process for ethanol or biogas production from cellulose inblended fibers in waste textiles”, Waste Management (2010), 30 (12), 2504-2509.
4- Enhancement of solubilization rate of cellulose in anaerobic digestion and its drawbacks”, ProcessBiochemistry, in press
