“…Flower waste, cow dung and saw dust contained 82.01, 80.10 and 16.71% of moisture content, respectively. Singh and Kalamdhad (2014) reported that bulking agent regulates moisture content and provides free air passage. In pile P 0 (100 kg), flower waste lump formation was observed on the third day and it was possibly due to excess moisture content and lack of air passage between the particles.…”

“…The sample was digested before analysis by heating 0.2 g dry sample with a ratio of 5:1 of 10 mL H 2 SO 4 and HClO 4 at 300°C for 2 h. The digested sample was used for determining the total phosphorous present using stannous chloride method (APHA 2005;Singh and Kalamdhad 2014). The concentrations of Na and K were determined using flame photometer (Systronics 128l) and the concentrations of calcium (Ca), copper (Cu), zinc (Zn), manganese (Mn), iron (Fe), chromium (Cr) and magnesium (Mg) were determined by Inductively Coupled Plasma Atomic Emission Spectroscopy method.…”

Purpose Flower waste dumping in landfills and other disposal sites is causing major environmental issues due to its highly biodegradable nature. Instead, flower waste can be successfully composted for its higher nutrient value. Therefore, this study evaluated the pile composting of flower waste with different combinations of cow dung and saw dust to produce stabilized compost. Methods Five agitated piles of flower waste mixture were formed in trapezoidal shape to perform the composting. Pile (P 0 ) was a control experiment, which contained 100 kg flower waste. The quantity of flower waste mixture with cow dung and saw dust in the other Piles was a total of 100 kg i.e. P 1 (50:40:10) kg, P 2 (60:30:10) kg, P 3 (70:20:10) kg and P 4 (80:10:10) kg, respectively. Results Temperature above 50°C was observed in all the piles except in P 0 . Physico-chemical characteristics of compost showed a stabilized compost obtained by proportionate mix of flower waste, cow dung and saw dust. Pile P 2 was observed with pH 7.23 and electrical conductivity 3.98 mS cm -1 , total organic carbon 30.9%, total nitrogen 2.31% and C:N ratio 14, thus a good proportion for compost amongst all the piles. Conclusions Appropriate proportion of waste mixture played an important role in providing favorable conditions for the microbial transformation of flower waste to stabilized compost. Temperature influenced the growth of microbes and maximum temperature was helpful in fast degradation of organic matter. Finally, flower waste with a combination of cow dung and saw dust was found to be successful during pile composting.

In Tunisia, the Joogar constructed wetland treating rural wastewater generates annually a considerable biomass of Arundo donax and Typha latifolia with sewage sludge. These by-products can present a waste management challenge for such systems. The present work focused on recycling of macrophyte residues by co-composting with sludge. Different quality physico-chemical parameters (temperature, pH, organic matter (OM), carbon to nitrogen (C/N) ratio, nutrients, and heavy metals) and biological factors (total and faecal bacterial count and germination test) were monitored during the composting cycle. Compost phytotoxicity was assessed through amendment assays. At the end of the composting cycle, temperature, and pH were stabilized at 33°C and 7.34, respectively. OM showed a significant mineralization and the C/N ratio was reduced from 31.7 to 9.0. In addition, pathogens destruction occurred at the later stages of the process. The final germination index of 96% indicated, with the other parameters, the stability and maturity of the macrophyte residues compost. The amendment assay applying compost to soil in a ratio of 1:2 v/v significantly improved the Lens culinaris growth by providing nutrients. The composting process appeared to be as a suitable way of valorisation of constructed wetland wastes, producing stabilized compost that could be sufficient for soil fertilization and plant growth improvement through a beneficial nutrients input.
