Sustainable Beverage Packaging Materials: which is considered optimal?

Today, there are a number of beverage packaging materials available. Aluminum, steel, glass, PET, so name some of them. However, it is not still not clear which one stands for truly sustainable beverage packaging material. The metals can be recycled (almost) indefinitely, glass can be reused, PET can be recycled and - if not - it can be used as direct fuel substitute. Does the sustainability of the material depend on the beverage? Or on the supply chain? Is it useful/healthy to re-use PET-bottles? Is steel can recycling truly sustainable? What happens with the aluminium lid and plate? A number of questions/issues that is addressed in a recent debate launched by Sustainable | Water | Management. The results may assist in creating ideas for sustainable packaging alternatives also with regard to bottled water.

Renewables - Part I: Is Solar Energy Ready To Compete With Oil And Other Fossil Fuels?
- a status note -

Image
reprint The solar energy industry may prove to be a dark horse in the race to provide global energy security. The world has renewed its interest in solar energy investment as it searches for a cleaner and more sustainable alternative to conventional fossil fuels. Countries like China , Germany, the UK, the US, Japan and Canada have already made significant investments in solar power . Who are the other players who are investing big in solar energy? With its own set of limitations such as high installation costs and high plug-in time, are consumers across the world ready to choose solar energy to power their daily lives? Or, are the conventional energy sources still the best bet? The best part about solar energy is that it is abundant and freely available, at least in most parts of the world. However, the high upfront costs of a photo voltaic panel remain a concern for many. Things are changing fast, however, and according to data from SEIA, the cost of an average PV system i

The Red Line: The Potential Impact on Asia Gas Markets of Russia’s Eastern Gas Strategy

Image
  reprint Russia possesses the potential to produce significant gas from its Eastern Regions, with total proved reserves  in  East  Siberia  and  the  Far  East  of  Russia  standing  at  5  trillion  cubic  metres  (Tcm)  while prospective  resources  could  be  as  large  as  65Tcm. This  would  appear  to  give  Russia  a  huge opportunity for export sales into the Asia Pacific region , which contains the world’s largest LNG importing  nations  and  two  of  the  world’s  fastest  growing  gas  markets   in  China  and  India   (also importers  of  LNG). It  is  surprising,  therefore,  that  despite  the  obvious  commercial  logic  of  linking enormous gas resources to expanding consumption centres, to date Russia’s only significant exports in  the  region  are  from  the  Sakhalin  2  project,  which  currently  sells  10.8mt  (14.6  Bcm)  of  LNG  per annum  into  the  neighbouring  Asian  markets . However,  it  is  possible  this  situation  could  change significant
