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 wastewat...
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 a...
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, is collected
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...
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
