20 Organic Waste Recycling: Technology and Management
1.6 EXERCISES
1.1 List the major types of organic wastes available in your own country and
give examples of organic waste recycling practices being undertaken there.
1.2 Based on the data given in Table 1.1, give reasons why the percent
coverage of urban and rural sanitation in the year 2000 is not much higher
than in the year 1990. Suggest measures to increase these coverage
percentages.
1.3 Find out the current practices of agricultural fertilization in your country
with respect to the use of chemical fertilizer. How can you convince the
farmers to use more organic waste fertilizer?
1.4 Conduct a survey, through interviews or questionnaire, about the public
acceptance of the following methods of organic waste recycling:
composting, biogas, production, algal production, fish production and crop
irrigation. Based on the survey results, rank the public preference of these
waste recycling methods and discuss the results.
1.5 You are to visit an agro-based industry or farm and investigate the present
methods of waste treatment/recycling being undertaken there. Determine
the potential or improvements that can be made at the industry or farm on
the waste management aspects.
1.6 From the website of the Millenium Development Goals
(www.un.org/millenium goals), find out: (a) which Goals and Actions are
most relevant to the situations of your country and (b) measures being
implemented in your country to achieve these goals.
