![]() Air Products is supporting the project along with several manufacturers of grinding equipment, and Burmester has been closely involved. The 2 0 0 kg/h pilot plant, which is equipped with six different mills, was started up on 10 November.“This plant is unique – no university or company in the world has such a wonderful facility for cryogenic grinding,” said Burmester. Now a new independent pilot plant and consultancy service dedicated to cryogenic grinding is set to change engineers’ perceptions of this method of size reduction Based at Oberhausen in the Ruhr area of Germany, the facility is run by Fraunhofer Umsicht, a research institution specialising in environmental, safety and energy technology that forms part of Germany’s Fraunhofer Gesellschaft. But as he pointed out: “Unfortunately, all too often it’s put in a box marked ‘too expensive’”. Cryogenic grinding is a proven Technology that is extremely effective, especially for plastics and rubbers, according to Frank Burmester, an engineer with industrial gas supplier Air Products in Germany. To achieve these temperatures, the materials are presently cooled with liquid nitrogen (LN2), which is followed by high operation costs. At low temperatures, many materials become brittle so that they can be grinded more effectively. The study concluded that cash flow problems, fraudulent practices in the industry and the nature of construction environment are the major factors affecting performance of SSLGC in Nigeria and the study recommended that local governments in Nigeria should devise a good cash flow policy, stringent penalty to persons involved in any fraud activity and thorough site investigation and documentation before embarking at any project.Ībstract:-The production of finest powders of viscoelastic and plastic materials is often very energy consumptive and therefore expensive or even not possible at ambient temperatures. Questionnaire survey was administered to the major parties in the industry clients, contractors and consultants using proportionate stratified random sampling and the results indicates that cash flow scored the mean value of 3.77, fraudulent practice was 3.58 and nature of working environment 3.51 means, the three factors fall into the classification of very severe impacts factors contributing to the poor/low performance of contractors in Nigeria. ![]() Three major factors namely: cash flow problems, fraudulent practices and the nature of construction environment are identified as the major factors affecting performance of SSLGC. This study aimed at identifying and assessing the major factors affecting performance of SSLGC in Nigeria. Yet very few researches have done to assess the performance of SSLGC. Studies in the past focus most attention on the productivity of major foreign construction firms mostly owned and managed by expatriates. The performances of small scale local government contractors (SSLGC) pose a challenge to the sustainable development of construction industry particularly in developing countries such as Nigeria. ![]() Comparison of the Fairness of tax based on establishment time using t-test show that that there was no significant difference between MSEs based on establishment time and result of comparison of MSEs on Profitability in relation to establishment time show there was no significant difference among MSEs regarding profitability. ![]() The qualitative data were analysed using narration. Quantitative data obtained were analysed using descriptive statistics and independent sample t-test. The data obtained were analysed using both quantitative and qualitative techniques. The data were gathered using questionnaire and interview. Stratified random sampling was used to get information from different sizes of the SMEs.The data were collected from 197 micro and small enterprises and micro enterprise offices in Western Hararghe. The sample of the study consists of all the micro and small enterprises and micro enterprise offices in Western Hararghe. The greatest challenges of micro enterprises, opportunities of micro enterprises, the roles of micro enterprises in employment generation, the roles of micro enterprises in entrepreneurial development had been identified. The present study aimed to investigate the Problems, Prospects and the role of Micro and Small Enterprises in economy the case of Western Hararghe.
