Volume 10, Issue 1 , March 2019, Pages 38-42

  Multilayer Packaging wastes are one of the major problem in the world. About 6 billion tons of packages are generated per year in the world (in EU is about 82 million tons per year). Multilayer packaging foils are approximately 17% of all produced packaging films. Most produced multilayer film is based ...  Read More

Modern Technologies of Natural Manure Treatment in Livestock Production

K. Mazur; K. Roman; K. Borek

Volume 10, Issue 1 , March 2019, Pages 43-48

  About methods of reduction of ammonia emissions and greenhouse gas (GHG) from livestock production were investigated. Many techniques required high investments costs by low reducing level of emissions. Among all known methods, the most effective method is slurry cooling and decreasing slurry pH to obtain ...  Read More

Recirculation of Process Water in a Wet Fermentation of Organic Fraction of Municipal Solid Waste

A. Zentner; C. Dornack

Volume 10, Issue 1 , March 2019, Pages 49-57

  The mechanical biological treatment plant of Freienhufen is used to stabilize residual waste. Since the rural districts Elbe - Elster and Oberspreewald - Lausitz match their waste management with federal law, organic fraction of municipal solid waste (OFMSW) will be collected separately in future. Hence ...  Read More
