conclusions the produced compost in this study was mature and ready for use as an agricultural substrate or soil conditioner after 80 days of composting. results the results showed that the c/n ratio decreased during the composting process (reached to 15.6) due to the loss of carbon and the increase in nitrogen content per unit material; also, the nh4+/no3 ratio decreased with increase in the t...

fly ash is one of the most plentiful and versatile of the industrial by-products. at present, nearly 150 million tonnes of fly ash is being generated annually in india posing dual problem of environmental pollution and difficulty in disposal. this calls for establishing strategies to use the same effectively and efficiently. however, it is only in geotechnical engineering applications such as t...

BACKGROUND Since July 2015, Lebanon has been experiencing a waste management crisis. Dumpsites in inhabited areas and waste burning have emerged due to the waste accumulation, further adding to the gravity of the situation. However, the association between the crisis and health of the population has not been scientifically reported. METHODS A comparative cross-sectional study was conducted to...

This study examined the waste management beliefs and practices of selected households in a Philippine rural municipality.  The sample used for this study involved rural families comprising of 332 households, which was drawn from the population using multistage cluster unequal allocation sampling technique. Descriptive statistics was used to analyze data gathered. Findings show that households e...

The analysis of solid waste or incinerated residue for information regarding the chemical constituents involved the development and adoption of analytical methods. Methods were developed for the determination of nitro­ gen, carbon, hydrogen, protein, chemically decomposable organic and calorific values. The chemical composition of two types of residue and unburned solid waste was de­ termined u...

This discussion explores the possibility of having a measure of the biodegradable organic carbon content in solid wastes. Currently, indirect measures for determining the concentration of biodegradable organic matter are being used and most of them are based on respiration indices (oxygen consumption or carbon dioxide production) or chemical parameters (volatile solids or total organic carbon)....

An interface to ADM1 was developed to estimate the solid waste composition from its practical characteristics. The interface was based on COD, elemental, charge and covalent bond balances to conceal any error in collected characteristics from different sources. The interface was validated by reported characteristics of manure and food wastes and determined with relevant accuracy the wastes’ com...

It is crucial to achieve effective solid waste management involving not only formal/government agencies, but also individual/informal/voluntary actions in order to create a healthy environment. This study conducted to unveil the factors that increase individuals’ community participation in solid waste management policy. The data were matched with a literature review on existing waste policies t...
