AbstractAbstract
[en] This study focuses on activated carbon preparation from spent mushroom farming waste (SMFW) via chemical activation using Box-Behnken design (BBD) of Response Surface Methodology (RSM). Potassium hydroxide (KOH) functions as activating reagent and it play an important role in enhancing the activated carbon porosity. Three input parameters and two responses were evaluated via this software generated experimental design. The effects of three preparation parameters of impregnation ratio, activation time and activation temperature as well as two responses of carbon yield and iodine number were investigated. The optimum conditions for preparing activated carbon from SMFW was found at SMFW: KOH impregnation ratio of 0.25, activation time of 30 min and activation temperature of 400 degree Celsius which resulted in 28.23 % of carbon yield and 314.14 mg/ g of iodine number with desirability of 0.994. The predicted results were well corresponded with experimental results. This study is important in economical large scale SMFW activated carbon preparation for application study of adsorption process for metal treatment in wastewater with minimum chemical and energy input.

AbstractAbstract
[en] Radiation has always been a natural part of environment. It is valuable working resources for civil, chemical and environmental engineers and scientist involved with pollution control, water treatment and industrial waste treatment. Electron beam technology for environmental conservation can be achieved if we took into account the economic factors which enable it to compete with existed technology.

AbstractAbstract
[en] The decomposition of municipal solid waste outdoors, or in some cases burning under the same conditions, is action now and final disposition of these wastes without measuring their consequences. In the student's residence 'Antonio Maceo' Orient University is hosting up to 2250 students belonging to a total of 22 university, generating at full capacity, 3375 kg / day of MSW. This research aims to analyze the solid waste generated in the student's residence, where improperly evaluated the final disposition thereof. It was found that discharges are not separated at the source observed at the landfill, food waste, sweeping waste, paper and cardboard, plastics, glass, metal, textile waste, wood, etc. Samplings were carried out directly in 12 rooms of the residence for a total of 48 people, along with students, as part of the educational activities implemented within this work. The average weight of degradable waste generated was 2.5 kg / day during the sampling, revealing the presence of traces of cooked food (cereals, legumes, carbohydrates), fruit and vegetable remains, remains of shells of different origins ( meats, eggs), remnants of tea, etc. The average content of total solids in the waste sampled was 36.3 ± 5.4% and volatile solids content on dry weight was 81.3 ± 2.5% to an average density of 0.68 g / cm3. This residue is characterized to be treated in an anaerobic batch reactor where it is recirculated leachate and studied the competing microorganisms in the anaerobic degradation of organic fraction of municipal solid waste.

AbstractAbstract
[en] Given that biomass plays a part in a complex natural cycle of decay and re-growth, providing the feedstock for a variety of often slow and subtle natural cycles, there are clearly limits to how much can be burnt without undermining key biological processes. This paper focuses on energy from waste, since, we argue, waste combustion is one of the more problematic options in terms of environmental sustainability, and we attempt to make a preliminary life cycle assessment of its impact. This suggests that the overall impact will depend not just on the total amount of wastes combusted, but also on their specific organic qualities, and on their role if they had not been diverted, in particular their role in maintaining soil quality. Given that soil plays a significant part in the process of carbon sequestration, we argue that consideration should be given to the concept of conservation of organic potentials. (Author)

AbstractAbstract
[en] Two composting processes were carried out; they lasted for about 165 days. In one of the processes the decomposition of the material was performed only by microorganisms only (direct composting) and in the other one, by microorganisms and earthworms -Eisenla foetida- (indirect composting). The first one was carried out in a composting system called camasand the indirect one was carried out in its initial phase in a system of panelas, then the wastes were transferred to a cama. The materials were treated in both processes with lime, ammonium nitrate and microorganisms. Periodical samples were taken from different places of the pile and a temperature control was made weekly. The following physicochemical parameters were analyzed in each sample: Humidity, color, pH soil : water in ratios of 1:5 and 1:10, ash, organic matter, CIC, contents of carbon and nitrogen and C/N ratio. In the aqueous extract, C/N ratio and percentage of hydro solubles were analyzed. It was also made a germination assay taking measurements of the percentage of garden cress seeds (Lepidium sativum) that germinated in the aqueous extract. The parameters variation in each process let us to establish that the greatest changes in the material happened in the initial phases of the process (thermophilic and mesophilic phases); the presence of microorganisms was the limiting factor in the dynamic of the process; on the other hand, the earthworm addition did not accelerate the mineralization of organic matter. The results let us to establish that the color determination is not an effective parameter in order to evaluate the degree of maturity of the compost. Other parameters such as temperature and germination percentage can be made as routine test to determine the process rate. Determination of CIC, ash and hydro solubles content are recommended to evaluate the optimal maturity degree in the material. It is proposed changes such as to reduce the composting time to a maximum of 100 days and to make the composting in a system of panelas

AbstractAbstract
[en] Removal of Cu (II) ions from aqueous solution by sawdust of wood was investigated as function of time, pH, adsorbent concentration, adsorbent concentration and temperature. The amount of Cu (II) ions adsorbed onto sawdust increased with the increase in reaction time, concentration and temperature. Kinetic studies showed that adsorption process followed first order kinetic model. Langmuir and Freunds equations were applied to the observed data, which showed that Cu(II) ions adsorption obeys both Langmuir and Freundlich isotherms. Thermodynamics parameters such as del H, del S and del G were also estimated which suggested that the adsorption of Cu (II) ions on sawdust of wood was an endothermic and spontaneous process.
