Industries in New York State and across the United States need to implement waste minimization programs. The highest priority for these management programs is the elimination and reduction of wastes, then, any waste which cannot be eliminated or reduced should be evaluated to determine if any recycling opportunities exist either onor off-site. Due to the complex interaction of production, proce...

Every industrial unit generates wastes along with the processed goods. These wastes actually represent loss of the valuable material and energy from the production processes and investment in the pollution control. Usual approach followed by the industries, to cope with the problem of wastes and pollution, is use of waste treatment systems as end-of-pipe remedies. The remedies adopted often res...

The thesis provides a presentation of the two conceptual models of industrial system material and energy flows in terms of sustainability; the dominant and the unsustainable throughput flow model and the potential future sustainable roundput model. These two material and energy flow concepts serve to illustrate the main research agenda of the emerging research and practical field of industrial ...

BACKGROUND The aim of the study was to design and implementation of integrated solid wastes management pattern in Shahroud industrial zone, evaluates the results and determine possible performance problems. This cross - sectional study was carried out for 4 years in Shahroud industrial zone and the implementation process included:1- Qualitative and quantitative analysis of all solid waste gener...

Residues are produced in all stages of human activities in terms of composition and volume which vary according to consumption practices and to production methods. Forms of significant harm to the environment are associated to volume of generated material as well as to improper disposal of solid wastes, whose negative effects are noticed more frequently in the long term. The solution to this pr...

The environmental performance of industrial anaerobic digestion (AD), pyrolysis, and integrated system (AD sequence with pyrolysis) on food waste treatment were evaluated using life cycle assessment. The integrated treatment system indicated similar environmental benefits to AD with the highest benefits in climate change and water depletion in addition to the increased energy generation potenti...

As a clean energy source and industrial material, hydrogen is very valuable. Electrolysis of water and chemical methods are well-known for producing hydrogen, however, all of these methods need additional energy supply. Besides highly energy cost, the chemical methods will lead to serious environment pollution. Compared with traditional methods, biological production of hydrogen has showed sign...

experiments were set up to estimate the effectiveness of clinoptilolite for the removal ofarsenate from aqueous solutions. the removal of arsenate by the exchanged forms was analyzed in thelight of the langmuir model of adsorption. a kinetic study of adsorption was carried out at differentintervals of time, and the kad values were calculated by using lagergren’s equation. adsorption ofarsenate ...
