It is true that the increase in population has led to exponential increase in demand for energy leading to gradual depletion of fossil fuel reserves. Therefore arises the need to search for alternative renewable clean and sustainable energy resource. Biomass derived fuels offers the best alternative to fossil fuel. Pyrolysis is one of the techniques used to produce biofuel from biomass. Thermal decomposition of biomass in limited supply of oxygen leads to emissions of complex matrices that affect biofuel utilization and stability. The major by-products from biomass pyrolysis include liquid oil, biochar and gases depending on operating conditions such as temperature, particle size, heating rate and reactor configuration. Biochars generated tend to find its use majorly in industry, agriculture and cleaning of industrial waste. Nonetheless biochars may contain organic compounds such as furans, aldehydes, polyaromatic hydrocarbons (PAHS) and environmentally persistent free radicals which are of toxic, carcinogenic, cause oxidative stress and mutagenic. This review therefore focuses on the characteristics of biochar in terms of morphology and the nature of persistent free radicals embedded on the surface of the biochar. It is notable that the information on optimum conditions for production of biochars free of persistent free radicals is scanty if any.","PeriodicalId":251059,"journal":{"name":"Editon Consortium Journal of Geography and Environmental sciences","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128781464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The establishment of colonial rule led to a considerable transformation in the environmental conditions of Machakos County. Human activities have always changed the physical environment, but the scale and impact grew enormously during the colonial period. In order to survive, the Akamba responded to the altered environmental conditions under the demands and restraints of colonial policies. Forceful destocking in the context of land alienation is discussed in this article from the political ecology theoretical framework. Akamba response to these changes is demonstrated as well as the consequent reaction of the colonial administration. Data for the article was drawn from both primary and secondary sources. Primary sources included archival records at the Kenya National Archives (Nairobi and Machakos). Both published and unpublished works were used to collect secondary data. Descriptive data analysis using qualitative methods of content analysis was applied. This article concluded that political considerations were made in regard environmental conservation. The intersection between colonialism, resource utilisation, and local and international politics fall in the context of environmental history. The area recommended for further research is the Second World War, the Mau Mau war and the clamour for independence as relates to land and its resources in terms of environmental conservation in Machakos County.","PeriodicalId":251059,"journal":{"name":"Editon Consortium Journal of Geography and Environmental sciences","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127883160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
