manufacturing industries in the form of effluents ...
In this study, waste corrugated cardboard (WCC) was selected as a feedstock to prepare carboxymethyl cellulose. Compositions of untreated WCC were α-cellulose 63.09±0.985%, hemicellulose 10.85±0.924% and lignin 11.92±0.351%. ...
Postharvest loss of tomato is high globally as well as locally in Ethiopia. The losses are due to physiological changes, microbial spoilage, mechanical injuries, and lack of suitable handling and storage mechanisms. In ...
The majority of the antimicrobial compounds used for treating textiles are synthetic based and are not considered to be environmentally friend. Therefore, solanum incanum fruit and onion peel were selected for the current ...
The high cost of chemical coagulants and their accessibility for water treatment makes most people in rural community to resort to readily available surface water which are usually of low quality exposing them to different ...
There is an increasing demand for biodegradable bioplastics, which can replace petroleum-based non-degradable plastics, which have a great impact on the environment. Starch-based biodegradable films are thermally unstable ...
Partial replacement of fossil fuels by biomass based alternative fuels is considered as a possible option for household applications. These are becoming a primary choice due to diminishing petroleum reserves and increasing ...
Background– Human immunodeficiency virus/ Acquired immunodeficiency syndrome (HIV/ AIDS) remains a major global public health problem, mainly to the sub-Saharan African countries. The consequence of HIV/AIDS is serious ...

Currently, Essential oils are widely used in various fields of industries such as perfumers, food industries and pharmaceuticals. The main objective of this research was to extract and characterize essential oil from ...
The problem of environmental pollution and health hazards due to inappropriate solid waste disposal is critical in developing countries like Ethiopia, Assosa town is one of the town in Ethiopia facing from environmental ...
In this study, optimization has been applied to chemicals such as phosphate, lime and
SO2 on juice clarification in the cause of MSF to reduce sucrose losses with filter cake
and final molasses and to minimize scale ...
This study has been conducted to do life cycle environmental impact assessment for cement –mortar brick household bio-digester and reinforced fiberglass household bio-digester. Primary and secondary data are used for the ...
This research mainly studies the effect of potato peel phenolic compound on cow butter as a preserving agent. It was extracted from potato peel (solanium tuberosom species) waste which delays spoilage and oxidation of most ...
A mathematical model was developed to describe the heat and moisture transport pro
cesses occurring in the convective drying of injera. The numerical systems of heat and
moisture partial differential equations (PDEs) ...
Waste stabilization ponds are sanitation technologies that consist of open basins that use natural processes to treat domestic wastewater and sludge, as well as animal or industrial wastes. The main objective of this thesis ...
The study focuses on modeling of temperature profile during beer fermentation and selecting modeled temperature to simulate with a growth of a microorganism, ethyl ethanol formation, carbohydrate (glucose, maltose, and ...
Many process parameters influence the properties of rigid PVC pipe. In this study, influence of CaCO3, thermal stabilizer as well as mixing temperature of the feed material and melting pressure of extrusion process; on ...
Due to its flavor, aroma and stimulant nature, coffee becomes the second most drinkable liquid next to water all over the world. These natures develop very well during roasting, but there is a problem of partial charring ...
