Exploring new sources of renewable energy

An SABMiller plant in the Czech Republic

One of the ways to reduce CO2 emissions is through replacing the current energy supply with greener alternatives. In the Czech Republic, Plzeňský Prazdroj has recently established and completed pilot work at Radegast Brewery Nosovice with a local University to evaluate the feasibility of the anaerobic digestion of waste streams from the brewery process.

From this analysis, it is now possible to compare the life cycle effectiveness of different options of generating renewable energy from waste streams.

Other pathways for producing energy from waste are the direct combustion of spent grain and other solid waste, or the production and recovery of fuel ethanol from these waste streams. The details of these pathways are also under investigation so that the business can make decisions on their most sustainable solutions.

Taking an integrated approach to packaging reduction

Our Czech business, Plzeňský Prazdroj, recycles or reuses 92% of its packaging material returned (the Czech average is 69%), mainly through the use of returnable bottles, kegs and beer tanks. The remaining 8% consists of non-returnable bottles and cans.

Last year the business completed a lightweighting exercise to reduce the average weight of its glass bottles to 0.64g/ml.

Plzeňský Prazdroj has also taken part in a project conducted by the Ministry of the Environment to analyse the life cycle of its packaging. Packaging was tested against criteria such as global warming, ozone layer damage and acidification. Composite packaging, usually made of more than one material, had the lowest overall environmental impact, followed by returnable glass bottles. Aluminium cans had the greatest impact. The findings of this environmental impact study will be used to evaluate the current packaging mix and identify further areas for improvement.
