Advanced analysis of cemetery waste

Cemetery waste is specific due to its material composition and due to its small quantity (approximately 1,100 tonnes from the 11 cemeteries in Brno in 2009). It is necessary to know the waste material composition to find the best way of its treatment and utilization. Therefore an advanced analysis of cemetery waste material composition has been carried out.Samples were analyzed in 2009 and 2010. In 2009 samples were analyzed due its biodegradation and in 2010the analyze was advanced to assessment of combustible and incombustible fractions.The amount of non-biodegradable fraction of cemetery waste is about 23 %weight that is too much for waste composting. The amount of combustible part of non-biodegradable fraction is about 73 %weight. The combustible part of non-biodegradable fraction consist of plastic and paraffin parts, the incombustible part of non-biodegradable fraction consist of glass and metal parts. Unsorted cemetery waste (including biodegradable fraction that is combustible) consist of 94 %weight combustible parts.     ...

Weight changes of cemetery waste during long-term collection

The paper presents results of the experiment focused on the establishment of cemetery waste weight changes in time depending on the way of collection. The cemetery waste samples were collected at the Brno Central Cemetery and at the Brno-Lisen Cemetery. The samples were stored in an open area and in closed containers (composteiners).Weight of the cemetery waste samples was measured at week intervals for seven months (the end of April - the end of November). The amount of rainfall was measured as well.During these seven months of the experiment the cemetery waste weight was reduced to almost 71 % on average of initial weight but the weight of the samples was stabilized after three months and further sample weight changes were only minor. The rainfall influence tothe waste weight was just temporary. ...
