Status of Agro-Industrial Waste Used to Develop Construction Materials in Andhra Pradesh Region – India

In today’s world concrete is one of the major construction materials. With the growth in industrialization and urbanization the demand for the concrete has taken a new pace. Therefore, to fulfill the demand huge amounts of natural resources has to be exploited for the production of the cement because natural resources and raw materials are major constituents in the production. At the same time huge quantities of industrial and agricultural wastes are generating in developing countries and are posing serious risk to the environment as well as human health. So, by utilizing these wastes as a supplementary material in construction reduces the usage of natural resources in the cement as well as decreases the threat of wastes in the environment. Many researchers have proved the effective utilization of wastes in the construction industry as they are more reliable and promote sustainability. This paper reviews waste generation and its statistics as well as environmental implication caused by wastes. It also high lights the possible ways of wastes that can be used in construction, preparation of blocks, insulators etc. This study also provides summary of existing research about usage of Agri and industrial wastes in the construction industry. In addition, paper shows application of wastes in real time construction.

Towards Efficient Management of Solid Wastes: an Overview of Dumpsites in Ibadan Metropolis, Southwestern Nigeria

The impacts of dumpsites derived from contamination of soil, groundwater, surface water, plants, humans and the environment at large are becoming alarming. In response to the waste challenges and its implication on the environment, many researchers have carried out detailed investigations on open dumpsites using geochemical, hydrological and geophysical approaches. This write up aims at assessing the current environmental implication of open dumpsite towards efficient management of solid wastes.<br/> The report reviews and synthesizes existing understanding of four active dumpsites in Ibadan to provide a general assessment of the current state of knowledge on the dumpsites. Previous studies reviewed in this paper identified the threat that open dumpsites may pose to the environment from potential leaching of hazardous chemicals into the soil, groundwater and the eco-system at large. Recent research revealed that groundwater, soils and plant found in close proximity with the dumpsites tend to accumulated heavy metals which indirectly has a high influence on the environment.<br/> Due to the significant impacts posed by the continual usage of the dumpsites, government should provide standard landfill site, recycling and treatment facilities for effective management of the waste being generated.
