Solid filtered or centrifuged potato processing wastes were obtained from three potato processors in Idaho. The waste samples were dried and ground to pass a 2-nun sieve and added to soils at rates of 0, 2.5, 10, and 25 g/kg. The 100-g samples of Portneuf silt loam soil containing the waste material was incubated at 26 °C and decomposition of the added wastes was determined by measuring CO, evo...

Biodiesel is an alternative diesel fuel produced using transesterification method where edible or non edible oil and alcohol reacts in the presence of catalyst. Biodiesel is expensive than fossil fuels because of higher raw material and production costs. Solid coconut waste is an alternative raw material from waste and suitable for biodiesel production to lower the production cost. Solid coconu...

Solid waste management has been known to play an important role in public health and the environmental status of developing countries. Waste assessment can help researchers and governors in management programs and devising alternative plans in order to improve public health and economical savings. In the present study, statistical estimations regarding waste generation and type of solid wastes ...

In this study, we evaluated a two-step process for detoxification of waste roofing slate, involving cement hydrate removal and low temperature detoxification using oxalic acid. These treatments were conducted on raw material and intermediate product, respectively. Cement hydrate removal effectively eliminated most Ca-containing cement hydrate components from the raw material under the following...

Construction waste is considered as a major contributor of solid wastes in municipal landfills. Construction, renovation, and demolition (CRD) waste generated by the Canadian construction industry accounts for 27% of total municipal solid waste disposed in landfills. However, many researchers stated that 75% of what the construction industry generates as waste has a residual value and therefore...

Solid waste management is challenging in Phnom Penh city, Capital of Cambodia. The only one formal treatment taken is the final disposal of mixed waste into an open dumpsite. The current study analyses the physical and chemical characteristics of municipal solid waste disposed of in the dumpsite to assess their suitable handling methods. The current study found that the major compositions of wa...

This paper considers a bi-objective mathematical model for locations of landfills, transfer stations and material recovery facilities (MRFs) in order to serve the entire regions and simultaneously identify the capacities of landfills. This is a mixed-integer programming (MIP) model, whose objectives are to minimize the total cost and pollution simultaneously. To validate the model, a numerical ...

The moisture retention and compression characteristics of municipal solid waste under self-weight are likened to those of an unsaturated soil. By assuming that the solid organic fraction in waste retains a relatively immobile micropore moisture and that deformation at low confining stress occurs at the expense of a relatively large macropore system, an insight into the variation of density and ...

Waste disposal is one of the pressing problems.Millions of tons of municipal solid waste, hazardous/industrial wastes and agricultural wastes are handled daily throughout municipal areas. Each municipality confronts great challenges in disposing of its wastes in an efficient, cost effective and environmentally safe manner.Landfills in metropolitan areas are becoming full, and new ones are more ...
