abstract:
The aim of this study was investigation of the influence of powdering of briquetted tobacco dust on efficiency of aerobic composting process. The research materials were briquette tobacco dust characterised by exceptional hardness and dryness. The composting process of tobacco waste was conducted in natural conditions and in the pile system. The piles consisted of: pile I: briquetted tobacco dust with mature compost (municipal sewage sludge + wheat straw) and fresh municipal aerobic sewage sludge, and variant II of pile consisted of powdered tobacco dust briquette and additions like in the first variant of pile. The performed analysis (CT, NT, temperature, pH, conductivity, organic matter) and enzymatic activities indicated that composting of tobacco waste (both briquetted and powdered) with mature compost and sewage sludge in estimated C:N ratio is advisable alternative of this waste management to methods used so far. The composting process of powdered tobacco waste was more efficient, but it is important to emphasize that briquetted tobacco dust is also possible to compost.
