Systematic increase of demand for wooden biomass and fuels generated from it is the result of the need to fulfill European Union obligations. For those sawmills which very often operate on the verge of profitability it creates a chance for improving their efficiency. Those having a sufficient amount of raw material at their disposal should consider launching production of wooden briquettes, as such initiative does not require any significant investment and may be complementary to company primary activities. Profitability of such venture depends on numerous variables. The aim of this article was to determine the value of sawmill residue when processed further into briquettes taking into account the impact of various factors. The research took account of: material intensity ratio depending on the material used, sales price per unit of final product, the entrepreneur’s target margin, briquettes production cost as well as the cost of transport in case of those enterprises which do not possess their own raw material.
Active application of new progressive methods of binding materials treatment allows to solve ecological alongside with pure technological and economic problems. Mechanical activation and modification, as the most effective representatives of such methods, lead to substantial increase of binders quality. The use of such methods allows to control structure formation processes while forming polymeric matrix of a binder. It may become an effective regulator for expansion of volumes of ecologically safe binding materials usage due to displacement of ecologically hazardous synthetic resins and oil materials which are the source of harmful discharge in technological processes where binding materials are used.
Jednym z odpadów poprodukcyjnych powstających w zakładach przemysłu rolno- spożywczego w procesie produkcji skrobi ziemniaczanej, który stanowi źródło tzw. „biomasy nieleśnej” jest wycierka ziemniaczana. W pracy zaprezentowano wyniki badań wpływu parametrów materiałowo-procesowych na procesu zagęszczania wycierki ziemniaczanej, które przeprowadzono na stanowisku badawczym SS-3. Przeprowadzone badania pozwalają stwierdzić, że wycierka jest materiałem podatnym na zagęszczanie, a uzyskany granulat posiada wysoką gęstość (1106-1315 kg×m-3) i może być wykorzystany jako przyszłe ekologiczne paliwo stałe.
