Investigation on Household Waste Management and the Effects of Compost and Dilute Parts of Waste on the Growth of Plants

Abstract

Massive populations have led to an increase in open landfills and spreading waste in cities and communities. The purpose of the study was to quantify the amount of compost that can be produced from the examined household trash and to ascertain the effects of compost and plant dilution derived from household wastes. The recorded data of parameters in every 10 days for 6 months and there found strong correlation between those parameters. A selected parameter was then measured and recorded after six months (February-July 2024) of observation and nursing, and a correlation was made between the recorded and measured. Fifteen households were selected of Bangladesh Ordinance Factory residential area in Gazipur city where three bins were provided, 1st for raw kitchen waste/organic waste, and 2nd for the plastic waste and 3rd for the E-waste. Wastes were collected and weighted them periodically. The collected kitchen waste was recycled into compost and dilution and tested them in laboratory of the Department of Environmental Science, Bangladesh Agricultural University, Mymensingh, Bangladesh. Finally, the contents were applied into the two different types of test plant species (chilli and spinach). The value associated between family size and kitchen waste was 0.82, and the correlation between income and kitchen waste was 0.04. The amount of garbage produced in the kitchen climbs directly as family size and income increase. Compost had a pH of 6.26, which is less acidic than dilution, which had a pH of 7.4. Compost contains 12.27% organic C and is diluted by 1.12%. Additionally, compost has a dilution of 0.08% and an organic N content of 1.08%, both of which are advantageous for plant growth. Compost used for growing chillies has a moderately favorable link with budding and flower and a strong positive relationship with leaf number, fruit, and leaf size. Height exhibits a very weak link with spinach leaf size and a strong positive correlation with fruit. Height, leaf number, leaf size, blossoming, and fruit all showed a very strong positive correlation when spinach and chillies were sprayed in dilutions. It is evident that plants benefit from both compost and dilution, but that plants like spinach or chillies benefited more from dilution. The study is designed to find way to recycle household wastes. Recycled kitchen wastes to compost and dilution is a big option to reduce huge amount of wastes and on the hand it has great contribution to the home agriculture and in the environment and human health.
