Abstract Natural systems, human health, and artistic sensitivities are all threatened by plastic pollution in most developed and developing countries. Plastic has emerged as a major global threat with rivers serving as sink for transported plastics, emanating from the terrestrial environment as a result of human activities. Anambra State in Nigeria is arguably the business hub of the South-eastern part of Nigeria, with a massive output of plastic wastes daily from individuals, commercial activities and industries. Owing to an inefficient waste management system, plastic leakage into her drainage networks is a critical environmental challenge. The aim of this study is to geospatially model the vulnerability associated with the various plastic leakage factors to the environment. To achieve this aim, data on different thematic variables which include plastic waste density, slope, land-use, drainage density and distance to drainage network of the study area were modelled, Geographic Information Systems (GIS) was used to delineate the variables in order to obtain final risk map for the study area. The result of the study indicates that a total area very high risk is 1840.03 km2, this constitutes about 40.11% of the study area. Local Governments Areas (LGA) located in the southern part of the study area is more susceptible to plastic waste leakage, this could be linked to factors like high dense population and increasing rate of urbanization in the region. It is recommended that waste collection should be frequent, strategic and higher priority should be attached to the high risked area from this study. Anambra State Government also needs to work together with plastic recycling companies, for effective collection of plastic wastes in the areas classified as hotspots in plastic litter accumulation as one of the mitigation measures.

The increasing global waste plastic pollution is urging people to take immediate actions on effective plastic recycling and processing. In this work, we report the results of processing reclaimed plastic wastes from unsanitary landfill site in Kuwait by using a bench scale continuous auger pyrolysis system. The plastic feedstock was characterised. After a simple thermal densification process, the material was fed to the pyrolysis system at 500 °C. The pyro-oil and wax products were collected and characterised. The process mass balance was developed on dry basis, and the yields of pyro-oil, light wax, heavy wax and gases were 5.5, 23.8, 69.4 and 1.3 wt%, respectively. The findings have indicated that the reclamation of plastic waste from landfill was feasible in terms of the product distribution and characteristics. Further liquid analysis confirmed that the liquid products contained fractions that are comparable to petrol and diesel fuels. The wax products are viable and have potential application as coating, covering and lubrication.

The study focused on the caretaker committee and performance of local Government Council in Nigeria: A study of Anambra State 2008 - 2013. In Nigeria federal structure, the three levels of government have legislative responsibility for various services and functions. The fourth schedule of the constitution outlines the functions and responsibilities of local government. The objective of the study is to: determine if the imposition of the caretaker committee system is a constitutional provision of the local government system in Nigeria especially Anambra State; to determine if the adoption of the caretaker committee by the state government affected the capacity of local government to perform its functions. The theoretical framework adopted focused on structural functional theory propounded by Gabriel Almond and J.S. Coleman in 1960. The study adopted descriptive research design and relied heavily on both primary and secondary data. Questionnaire was the major instrument for data collection and data were analyzed by the use of mean. Based on the data analysis, the following findings were made: the imposition of the caretaker committee system by state government to local governments is unconstitutional, the adoption of the caretaker committee by state government endangered the local government system capacity to perform its constitutional function. The study recommended amongst others that the use of or appointment of local government caretaker committee should be condemned, caretaker committee should be made to spend only three months to allow for a constitutionally elected local government executive.

AbstractThe pollution of our marine and terrestrial environment by plastic waste is one of the most pressing global environmental challenges faced today. Developing a circular plastic economy and limiting plastic pollution requires multilevel actions from different stakeholders including oil and petrochemical producers, plastic manufacturers, consumer goods companies, retailers, consumers, waste managers, waste management authorities, plastic recyclers and others. As well as cleaning up the enormous quantities of plastic waste already in our oceans and lakes, there is an urgent need to strengthen countries’ capacities to prevent, minimize and properly manage this waste. The Basel Convention, the most comprehensive global environmental treaty dealing with hazardous and other wastes, offers an important part of the solution. In addition to its provisions aimed at controlling the exports and imports of hazardous wastes and other wastes generated from households and ensuring their environmentally sound management, the Convention also seeks to tackle the problem at its source through prevention and minimization. With the addition of an amendment to the Convention specifically tackling plastic waste, and the establishment of a Plastic Waste Partnership, the Convention is positioned at the forefront in the fight against plastic pollution.

The study examined the impact of Anambra Government’s Grassroots Development Scheme on economic empowerment of community dwellers especially the youths and women, in all the local governments of Anambra state, in Southeastern Nigeria. The purpose was to assess the major beneficiaries of the development scheme and determine the impact of the scheme on the common people especially the youth and the women. The work is anchored on community development theory which emphasizes holistic approach to development through participation of all tiers of government, from the federal administrative office to the regional and local governments to community dwellers at grassroots level. Primary data was used for the study. The questionnaire was used for collection of data. The number of respondents for the study is 975. Descriptive and inferential statistics were used for data analysis. The result of the study showed that a lot of the common people benefitted from the grassroots development scheme of the Anambra state Government. The hypothesis stated was tested at 0.05 level of significance to determine if the development scheme was beneficial to community dwellers of Anambra State using one sample Kolmogorov Smirnov Z test and it was rejected because the p value was less than 0.05 (Z=0.6.913, p=0.00). The research findings also showed that the development scheme of the Anambra state government had also impacted positively on the people of the state, especially the youth and the women. The statistical significance of this result was determined using Pearson Chi square coefficient. The hypothesis was because the p value was less than 0.05 (χ2=887.779, df =125, p=0.00). The study, therefore, concludes that the first tier of the grassroots development scheme of government in Anambra state impacted positively on the life of the community dwellers of Anambra state, particularly the youth and women. The study recommends that more of such development scheme should be embarked upon by different tiers of government and other states in Nigeria should replicate same in their own states. This will be a way of boosting the economy, reducing unemployment, and diversifying economic activities.

Plastic has achieved such an extensive market due to fact that it is lightweight, cheap, flexible and reusable. But now it is regarded as a serious hazard. All recommendation for and against plastics finally land up on the reality that plastics are slow to degrade. By the end of the 20th century, plastics are found as persistent polluters of many environmental niches, from Mount Everest to the bottom of the sea. There are numerous ways by which plastic pollution can be controlled.  Pyrolysis is referred to as polymer cracking and its main advantages are that it can deal with plastic waste .This paper provides an overview of the science and technology of pyrolysis of waste plastics. The major advantage of the pyrolysis technology is its ability to handle unsorted, unwashed plastic. The production of gasoline, kerosene and diesel from waste plastics is an emerging technological solution to the vast amount of plastics that cannot be economically recovered by conventional mechanical recycling. The disposal and decomposition of plastics has been an issue which has caused a number of research works to be carried out in this regard. Currently, the paper reviews the production of Petroleum-based fuel viz. gasoline, kerosene and diesel from recycling of waste plastics is an emerging technological solution to the vast amount of plastic wastes that cannot be economically recovered by conventional mechanical recycling operations. This involves the use of pyrolysis which permits recovery of valuable gasoline and diesel-range hydrocarbons from waste plastics that are otherwise land filled.

The increasing pollution in oceans, especially of the plastics litter, has degraded health of the oceans in many parts of the world. As plastic degrade very slowly, its accumulation in oceans expected to rise exponentially in coming decades and critically affect marine ecosystems, ocean fauna and humans. Microplastics, generated due to mechanical breakdown of plastic waste, is particularly affecting the pelagic ecosystems and can even alter them. It is necessary to generate and update scientific knowledge about production, transport, sink of plastics and their impacts, develop innovative approaches to manage plastic waste, and bringing awareness about effects of plastic pollution to communities. The issue of plastic pollution needs be tackled at local as well as regional levels through effective policy and multi-national cooperation.

The urbanization process contributes to the growth of solid waste generation and causes an increase in environmental impacts and failures in the management of solid waste. The number of dumps is a concern due to the limited implementation and safe disposal of this waste. The interest in sustainable techniques has been growing in relation to waste management, which is largely absorbed by the civil construction sector. This work aimed to review plastic waste, especially polyethylene terephthalate (PET), that can be incorporated with construction materials, such as concrete, mortars, asphalt mixtures, and paving. The use of life-cycle assessment (LCA) is related, as a tool that allows the sustainability of products and processes to be enhanced in the long term. After analyzing the recent literature, it was identified that studies related to plastic wastes in construction materials concentrate sustainability around the alternative destination of waste. Since the plastic waste from different production chains are obtained, it was possible to affirm the need for a broader assessment, such as the LCA, providing greater quantification of data making the alternative processes and products more sustainable. The study contributes to enhance sustainability in alternative building materials through LCA.
