ABSTRACT Circular economy requires sustainable supply of raw materials to industries. Social and economic networks are needed in order to develop circular economies that would drive value chains in renewable resource processing from wastewater into renewable bioplastic products. Current plastic is non-biodegraded which can cause harm to our environment. A pilot scale investigation was carried-out so as to evaluate the feasibility of producing value-added bioplastic from wastewater treatme...
ABSTRACT Nowadays, there is an increase in the demand to connect to the internal networks of organizations by their branches from distant locations. Members of such organizations often need to access internal networks from their homes, hotels or other far away business places and external networks over the internet which is insecure by virtue of its public nature. The security of information transferred in the network becomes a major challenge when staff or partners in business access in...
Road inventory is the compilation of information about the state and condition of the road system. This study was carried out to collect road data and analyze selected road facilities within the University of Ibadan to serve as an inventory for future purpose. This was done to help resolve the issue of insufficient information about the road facilities within the University premises. In this project a survey of the roads was done which involved the use of photo/video log system and the Glob...
EXECUTIVE SUMMARY This work presents the design of a plant that will produce 250000kg/yr of lindane from benzene, chlorine and water at high temperature and pressure using direct chlorination method. The feeds are sent into a chlorinator, the crude product from the chlorinator is continuously decanted into a decanter and the bottom product HCl i...
This research presents the effect of lye on the kinetics and quality of local soaps. To achieve this, 40ml of 10 percent lye (palm bunch, coconut shell and synthetic sodium hydroxide) reacted with 60ml of oil (palm oil and palm kernel oil) in a batch system, under conditions as, constant temperature (50 degree celcius) and constant stirring (100 rpm). Variation in saponification value and free fatty acid was monitored with time, that is, at intervals of 2mins. It was noticed that as time incr...
Quality control is a checking test to monitor and ensure the wastewater treatment plant (WWTP) is at optimum efficiency. The tests are usually carried out on samples collected from specific points or stations in the WWTP. The Influent sample, is collected after the fine screens. Aeration basin sludge, iscollected from the point of overflow of the aeration basin, before it is sent to the clarifier. Return Activated Sludge (RAS) sample, is collected from the sludge pumping station. Waste Ac...
Wastewater is made up largely of organic carbon, either in solution or as particulate matter. About 60% is in particulate form, consisting of proteins, amino acids, peptides, carbohydrate, fats and fatty acids. Wastewater treatment plant (WWTP) prevent potential waterborne disease outbreak. This is achieved by the active use of mechanical process and biological process of the treatment plant to treat and convert wastewater into clear effluent that meets specific standard. The effluent water...
CHAPTER ONE1.0 INTRODUCTION1.1 Background of StudyThere is need for affordable building materials in providing adequate housing for teamingpopulace of the world. The cost of conventional building materials continue to increase asmajority of the population continues to fall below the poverty line. Thus, there is the need tosearch for local materials as alternatives for the construction of functional but low-cost buildingsin bo...

ABSTRACT This study investigation on the mechanical properties of Sagbama rice granite was analyzed to determine the load that would cause ultimate flexural stress on the material when used in concrete construction .This is necessary to make decision on where it is suitable for use. This study requires the production of 12 concrete beams of 100mmx100mmx500mm with sagbama rice granite as coarse and fine aggregate. Three (3) specimens were produced to be tested at 7, 14, 21 and 28days.Mix rat...
The increase of salinity in soil and water bodies which simultaneously declines the productivity of agriculture is of great concern to the Nigerian Federation which holds agriculture as a major means of survival for its economy. Thus, the proper monitoring,use and management of soil and water bodies is a sure way to proffer solutions to food shortage and poor crop yields. This can however be achieved by the use of a fast, reliable, and accurate in-situ salinometer. A portable in-situ salinome...

Information and Communications Technology, like many other classical innovations has been institutionalized and become myths binding on organizations. How this seditious tool can be used as a catalyst for developing countries, in the face of empirical anomalies has been a cause for concern. Why does increasing number of agencies go on-line and establish similar web presences with similar structures even when delivery to end user is poor or near impossible? What are the processes of adaption ...
The study examined Broadband infrastructural deficit and the growth potentials of Information and Communications Technology in Cross River State of Nigeria, by using three–to-five scale closed-ended questionnaires. Cross River State has a population of about 3,104,446; yet by 2014, it was estimated that mobile Broadband connections in Cross River State was below 50,000 subscribers. Government statistics put Internet penetration in Nigeria at 28 per cent. Out of these, only less than 9 per c...
