Qualitative characterization of healthcare wastes

The biological hazard inherent in the clinical wastes should be considered during the management and treatment process as well as the disposal into the environment. In this chapter, the risks associated with the clinical wastes as well as the management of these wastes are discussed. The chapter focused on reviewing the types of healthcare wastes generated from hospitals and clinics as well as the regulations and management practices used for these wastes. Moreover, the health risk associated with the infectious agents which have the potential to be transmitted into the environment. It has appeared that the clinical wastes represent real hazards for the human health and the environment if they were not managed properly

The characteristics of retail wastes in the city of Yenagoa, Nigeria

&lt;p class="EbiBody"&gt;&lt;strong&gt;Wastes management is a clear strategy where wastes are channelled through processes that ensures proper storage, collection, transportation, treatment and disposal of wastes with ample consideration for environmental protection and public health. In Yenagoa where the current study was conducted, the lack of proper wastes management structure is apparent, particularly among retailers where samples were drawn from for the study. Little is known on the volume and characteristics of wastes produced by the retail sector in the city, like many other Nigerian cities.&lt;/strong&gt;&lt;/p&gt;&lt;p class="EbiBody"&gt;The study employed a mixed method approach using closed and open-ended questionnaires in collecting data. In all about 900 questionnaires were collected and analysed for the study. Knowing that no proper waste management plan can be developed until the current practice, sources, components and volume of waste has been well understood. The use of qualitative methods in this paper helps to better understand and gather data on areas of interest. A multi stage cluster sampling technique was employed due to the unavailability of an up-to-date sampling frame in the area.&lt;/p&gt;&lt;p class="EbiBody"&gt;The findings from the study show that wastes materials produced by retailers in Yenagoa are mainly wastes paper, tins, cans, plastics, cardboard, furniture, wood products and possibly WEEE. However, plastics and cardboard materials were the dominant wastes materials produced by the retail sector. The study therefore concludes that there is a need to establish a wastes processing facility in Yenagoa with heavy emphasis on recycling.&lt;/p&gt;</jats:p

NEUTRALIZATION EFFECT OF THE FLY ASH AND COAL DUMP WASTES

Acidic and/or alkaline wastes, or wastes that change their pH level over time, create an increased danger to the environment and human population. These wastes can be formed due to activity of all basic branches of industry (agriculture, energy, metallurgy, food, chemical, mining, production and processing of petroleum products, etc.)

Recycling

The environmental problems generated by our consumer societies require immediate measures that respect the principles of long term sustainability. However, in response to the rising amount of wastes (on average, per capita arising municipal wastes increased by 26 between 1970 and the late 1980s in the OECD) various (mostly end-of-pipe) waste management strategies have been advocated, while a real questioning of what constitutes 'wastes' is still desperately needed

Intellectual property as complex innovation projects component

The materials presented the possibilities development of intellectual property complex innovation projects modern highly effective science-based problems of improving the use of wastes of different industries on a complex enterprise that can provide all its energy needs alone. Some features of the possibilities of solving evidence-based problems of development of mechanisms for identifying syner-gistic processes, their scientific justification improving the use of wastes of different industries on a complex enterprise. The problem of wastes utilization and recycling is present as complex synergetic processes research and analysis of energy- and resource saving process-es for treatment of polymer wastes of various origin. The research focused on the study of issues such as the development of models of waste-modifying polymer. The investigation are focused in researching such problems as selection of scientific based methods of wastes to be utilized or recycled; the development of appropriated process flow sheets and choice of modifications additives and equipment for polymers waste recycling. The choice of appropriate plants with selected energy resources is very important for projects realization

Soluble and insoluble-bound phenolics and antioxidant activity of various industrial plant wastes

The potential of selected industrial food wastes from juice and nut production including apple peel, apple pomace, pomegranate peel, pomegranate seed, chestnut shell, and black carrot pomace as resources for natural antioxidants was investigated. Soluble free and insoluble-bound phenolics were extracted from the wastes and analyzed for total phenolic and flavonoid contents, phenolic profile and antioxidant activity. Total phenolic and total flavonoid contents of wastes were positively correlated with their antioxidant activity. The highest total phenolic and antioxidant activity were determined in soluble fraction of pomegranate peel due to a significant amount of punicalagin derivatives. Pomegranate peel and seed had the most phenolics and flavonoids in soluble form while other wastes had more than 45% of total phenolics in insoluble-bound form. Chestnut shell showed more antioxidant activity in insoluble-bound fraction compared to that of its soluble fraction. These findings showed that not only soluble but also an insoluble-bound fraction of the industrial wastes has good potential for valorization as a source of natural antioxidants

The complex binder based on Portland cement andash-and-slag wastes from thermal power stations

Increase in the balance of boiler and furnace fuel of the energy sector of the Republic of Belarus the proportion of own energy resources (milling peat and wood chips) places priority on resolving the issues of utilization of ash-and-slag wastes and reducing the area of ash-and-slag disposal sites, which cause irreparable damage to the environment. A considerable amount of research has been devoted to the utilization of ash-and-slag wastes. There are more than 300 technologies of their recycling and use. Ash and slag wastes are used in the production of concrete, mortars, ceramics, heat and water insulating materials, road construction. The world experience shows the potential of 70-80% utilization of ash and slag, as, for example, in some European countries. However, the cost of the recycling of ash-and-slag wastes with the production and simultaneous neutralization of wastes can be higher than the cost of the production. One of the directions of the use of ash and slag wastes is the production on their basis of new types of complex binder that have increased strength and low prime cost. The replacement of a part of cement with active mineral additive allows to achieve significant saving of binder. The existing methods of the production of complex binders include the stages of joint or separate grinding of cement clinker and mineral additive with following mixing. Significant energy costs for grinding increase the cost of binder. In this regard, the development of the effective complex binder with the use of ash-and-slag wastes of the Belarussian state district power station in Orekhovsk using resource-saving technology is the actual research objective
