Background and Aim: In the initial preparation stage, before feeding worms with organic wastes, the wastes are pre-composted for some time. This was done so that the thermophilic phase of organic wastes degradation is passed, no harm is done to the worms which are sensitive to high temperatures, production of fertilizer faster is quicker, and biological contamination is reduced. The length of t...
the possibility of using water insoluble fraction from biomass pyrolysis oil as additive in synthesis of wood-plastic novolac has been proved by using differential scanning calorimetry (dsc) and fourier transformed infra red (ft-ir) spectroscopy. synthesis of novolac with different concentrations (10, 20 and 30 wt %) of water insoluble fraction were performed. it was found that mechanical prope...
