ABSTRACT

Industrial wastes have major impact on the environmental quality both nationally and globally. The waste produced could be hazardous in nature. The aim of this research is to assess the solid waste management in Zaria industrial estate, Nigeria. The study employed questionnaire administration and in-depth interview instruments. The industries for this study were purposively selected namely, Sunseed industries, Premier Seed Company, Olam Nigeria Limited and Nalmaco Industry. A total of 398 respondents‘ within the industrial zone were sampled in order to get information on the effect the waste has on them. The studyemploys descriptive statistic in analysis of data by the use of frequency tables and percentage in presenting the data collected from the questionnaire administered to the respondent. Results of the analyses showed that impurities (9.5%), trash and refuse (10.7%), mote (5.6%), soap stock (10.6%), boiling ash (23.8%), etc are the major wastes produced by industries in Zaria. The industries adopted source reduction (37.9%) and recycling (36.3%) as a way of managing their waste. However, the effect of industrial waste management practice was majorly flooding (39.6%), water pollution (23.1%) and air pollution (16.3%) which was as a result of dumping solid industrial waste indiscriminately. And that community sensitization (54.9%) is what the industries use to report the effect of their waste to the community as a way of reporting waste to the community. Also, the compliance level of industrial with recommended waste management practices by NESREA showed that Sunseed (3.67) recorded the highest, while the least was Premier seed limited with (3.29) respectively. Due to the effects of the waste a high proportion of respondents (46.2%) migrated out of the community because of the health implication the waste has on them. Based on the findings, it is recommended, that a technically based personnel should be used to handle industrial hazardous wastes. Industries need to receive authorization from Kaduna State Protection Agency (KEPA) before disposing any hazardous waste and setting up of recycling plant within the industries to enhance recycling.
