i am reading about this on the BBC website ...
"Bags consume a valuable raw material and they have an environmental impact in their manufacture, their transport, use and disposal. Yet increasingly the debate has become focused on only one dimension of that - the disposal of bags"
well firstly , the resources are not 'that' valuable to make polyurethane. Yes they do have an environmental impact , particularly being within the chemicals industry.
i had a look at a random polyurethane company and
Welcome to Huntsman , proved quite good in the sense of striving towards a better environment - they have an active sustainability program : ISO 9001:2000,ISO 14001:2004 - these are both environmental standards certificates , usually done externally , but always ratified externally and particularly the latter one is to quite a high standard. With this in consideration .. and also the likliness that alot of these companies are at least becoming self sufficient power wise (depending on location)
The transport is not going to take a huge portion , because once the bags are made they are likely to be sent to a distributor and then as i have experienced in a supermarket they come combined with other orders etc
I am not going to tackle disposal because there is a problem , but its getting better, rather than taxing plastic bags they should put quotas on their supply, then i am sure the knock on will be to start charging for plastic bags like lidl do ..
i think i have verged into waffle feel free to pick it apart .. i think its getting to late in the day for posts as long as mine.
