Effects Of Banana Peels On Chicken Weight Gain And Egg Production In The Urban And Peri-Urban Areas Of Aksum City, Ethiopia, H. G. Araya, S. G. Gebrekristos, W. V. Oliver Jan 2022

Effects Of Banana Peels On Chicken Weight Gain And Egg Production In The Urban And Peri-Urban Areas Of Aksum City, Ethiopia, H. G. Araya, S. G. Gebrekristos, W. V. Oliver

IGC Proceedings (1997-2023)

High feed cost of running urban-animal-agriculture and huge city wastes are challenges of the growing towns in modern Ethiopia. Egg production microenterprise is steadily growing due to its low initial investment and ready market in urban and peri-urban areas. However, cost of egg production is high due to the rising cost of corn, the main feed ingredient in poultry rations. Using banana peels, which forms a great proportion of city waste in Ethiopia, is seen as a way of not only reducing the waste, but also as an alternative low-cost feed supplement that could help enhance egg production by small-holder …

Chapman University 2016 Environmental Audit: Residence Life Dining Services Equipment, Alexandra Fw Sidun, Devon T. Bloss May 2016

Chapman University 2016 Environmental Audit: Residence Life Dining Services Equipment, Alexandra Fw Sidun, Devon T. Bloss

Student Scholar Symposium Abstracts and Posters

Chapman University accommodates over 1700 student meal plans per day through the on-campus dining services provided by Sodexo Restaurant Services. The commercial-grade kitchens found in the Randall Dining Commons (RDC) of Sandhu Conference Center are frequently used to prepare food for students for every meal, seven days a week. The RDC kitchen facility has staff working around the clock and high consumption electrical, water, and gas appliances constantly running to parallel the high demand. The frequent use of commercial kitchen appliances results in an enormous consumption of energy and water resources leading to comparably high utility bills. Measuring the energy …

Biodiesel Transesterification Byproducts As Soil Amendments, Solomon Parker May 2013

Biodiesel Transesterification Byproducts As Soil Amendments, Solomon Parker

Graduate Theses and Dissertations

For every ten kilograms of biodiesel that is produced from the transesterification of vegetable oil, approximately 1 kg of glycerol is produced as a byproduct. Also known as glycerin, it is a chemical used in many products including cosmetics, foods, and desiccants. However, the crude glycerol created during biodiesel production is tainted with potassium hydroxide and methanol making it unsuitable for commercial use without costly refinement. With increase in production of biodiesel driven by rising fuel prices, the market has become glutted with glycerol and it is on the threshold of becoming a waste product. Common methods for disposing glycerol …

A Study On Solid Waste Management System Of Dhaka City Corporation: Effect Of Composting And Landfill Location, Faisal Ibney Hai, M. Ashraf Ali Aug 2012

A Study On Solid Waste Management System Of Dhaka City Corporation: Effect Of Composting And Landfill Location, Faisal Ibney Hai, M. Ashraf Ali

Faisal I Hai

This study has analyzed the generation and characteristics of solid waste in Dhaka city, along with the associated environmental impacts and existing solid waste management practices. Special focus was given on the effect of composting on final disposal of solid waste and effect of landfill site location on transportation cost. An estimate of the future generation rate indicates that the present generation rate of 3500 tons/day may exceed 30 thousand tons/day by the year 2020.The mixed waste dumped at dumping sites is characterized with high organic content and high moisture content (about 80% and 50-70% by weight, respectively). According to …


Environmental Problems Of Industrialization And Sustainable Development In Nigeria - A Review, Adejoh Iyaji Feb 2011

Environmental Problems Of Industrialization And Sustainable Development In Nigeria - A Review, Adejoh Iyaji

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

The main objective of this paper is to examine the impact of the quest for industrialization on the environment in Nigeria; others include, the identification of the objectives of sustainable development as well as making recommendations that will lead to the much needed sustainable environment both for the present generation and generations yet unborn. The researcher relied principally on secondary sources of data for this paper which is theoretical in approach. Findings revealed the emergence of a host of environmental problems such as air pollution, deforestation, desertification, solid and hazardous waste problems in the wake of the quest for industrialization. …

An Assessment Of Socio-Economic Impact Of Waste Scavenging As A Means Of Poverty Alleviation In Gwagwalada, Abuja., John Yakubu Magaji, Samuel Panse Dakyes

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

Waste scavengers are usually perceived as being among the poor, and scavenging is considered a marginal activity. They tend to have low incomes, but can obtained decent earning when they are not exploited by middlemen. This study was conducted in Gwagwalada town with the aim of assessing the socio-economic impact of scavenging on the people. A structured questionnaire was constructed to capture the demographic characteristics of the scavengers, their experiences, types of items scavenged, the economic gains and the challenges being faced. The target pollution is waste scavengers and a random sampling technique was adopted in selecting the respondents for …
