Biopesticide effect of compost generated from municipal solid waste

Indiscriminate disposal of Municipal Solid Waste (MSW) creates several environmental andpublic health problems. Composting of MSW involves managing conditions to accelerate thebiological decomposition of some of its organic components. In this process various bacteriaand fungi, break down organic matter into simpler substances. Compost derived from MSWcontains antagonistic microorganisms such as Bacillus subtilis, Trichoderma sp. AndPseudomonas sp., which can be used to control many soil borne plant pathogens.Germination experiment was carried out to ascertain the influence of the stabilization processof compost derived from MSW on its biopesticide effect when Fusarium oxysporum, a plantpathogenic fungus was introduced into Lycopersicon esculentum (Tomato). Water extract often-year-old compost derived from MSW with heat-treated soil in different proportions wereused in this experiment. The biopesticide effect of compost derived from ten and two-year-oldMSW collected at different depths was evaluated from the number of genninated seeds androot elongated measurement. The compost samples were analysed for moisture content, pH,electrical conductivity, total solids, volatile solids, fixed solids, organic carbon, organicnitrogen, C/N ratio, total phosphate, potassium, and total microbial count to assess thecharacteristics of the compost.Lycopersicon esculentum seeds inoculated with Fusarium oxysporum were placed in Petriplates. Seeds were watered with extracts of ten-year-old compost and heat-treated soil mixedin different proportions. Seeds without inoculation were maintained as control. After 8 days,the number of genninated seeds was observed and root elongated was measured. Then insteadof ten-year-old compost, two-year-old compost was used and the experiment was conductedin the same way.Addition of compost to soil resulted in the suppression of Fusarium wilt caused by Fusariumoxysporum. Microbial antagonism was responsible for this property. It was dependent onnutrient competition involving total micro flora of the soil and compost; and relied on themechanism of general suppression.

The City

The rapid increase in urbanization and population, is generating massive solid waste (SW) in cities. Mismanagement of MSW collection is creating, health hazards, socio-economic problems, and deteriorating environments. This research aimed to examine the SWM problems and to identify SWM issues through the inhabitant's perspective and to propose a sustainable method to control, collect, treat, utilize and disposing of Municipal SW in Sanghar City. Hence, the objective of this study is to achieve through cluster sampling, For the residential questionnaire study, a sample size of 384 was obtained and descriptive statistics and regression and correlation analysis methods have been used to evaluate the data collected. As a result, the collection of MSW is quite inappropriate and constricted to the influential area and solid waste keeps on scattered throughout the remaining areas. In recent years, mismanagement MSW has become a major problem in Sanghar city. The key problems of SW in the city are indiscriminate disposal, improper collection, inadequate storage, and insufficient facilities. To address these issues, the management of the disposal of SW must be carried out with the complete participation of the respective communities.
