The Impact of Unit Pricing System on the Demand for Solid Waste Disposal, Food Waste Disposal, and Recyclables

Abstract The impact of uncontrolled municipal solid waste disposal of 3800 tons per day on surface and groundwater in the downstream of Jawaharnagar dumping site was studied. The un-engineered solid waste dumping yard site spreading over an area of about 300 ha is located on topographic high (hillock), and falls in Madyala stream and Dammaiguda watersheds of Musi sub-basin. The area is underlain by granites of the Archaean age. Both surface and groundwater samples, collected covering hydrological cycles of 2011and 2012, were analyzed for major chemical constituents. During 2012, 15 samples of both seasons were tested for BOD, COD, and TOC. The mean values of some tested chemical constituents of surface water samples (15) were - EC 13066 m S/cm, TH 753, Na+ 813, K+ 530, HCO3− 978, Cl− 1304, and NO3− 262 (all in mg/l) which prove that the tanks and stream near dump yard were pools of leachate. The average values of contaminated groundwater samples among the four sampled sessions (17) indicate EC was above 5000 m S/cm, TH 1624, Cl− 1502, and SO42− 284 (all in mg/l) which were found much above the threshold values. Very few samples were found suitable for drinking purpose and most of the samples fall in Good class of WQI. Very high content of TOC, BOD, and COD in both surface and groundwater samples indicate the presence of organic pollutants sourced from domestic waste dumps. Wide temporal and spatial variability in the concentration of many ion species can be attributed to deviation in rainfall, topography, plume dynamics, and aquifer hydraulics. Low resistivity values (5 to 25 ohm.m) at a distance of 4 km from the dumping site and high infiltration rate (29 cm/hr) at Madyala stream, which were contaminant hotspots, indicate the mass flux was controlled by hydrological features. Scattered and limited distribution of contaminants can be accounted for heterogeneous nature of country rocks, retarded lateral and vertical flow of water which restricts the movement of contaminants to certain preferred pathways. The study supports the hypothesis of solid waste dumps were the epicenter of pollution which generates leachate and dissipate contaminants to the aquatic environment influenced by factors like soils, topography, and aquifer hydraulics and contaminant kinetics.

The Impact

The present study investigated the impact of solid waste disposal on the receiving soil quality of four major dump-sites and a control site in Benin Metropolis, Edo State, Nigeria by collecting samples at three distances from the dump-sites of 0 – 50 m, 50 – 100 m, > 100 m at 0 – 30 cm depth. The investigation spanned from July 2011 to December 2011. Results obtained during these months were pooled together to obtain single mean for each sampling station or distance. Results showed that pH values ranged between 5.23 and 5.83, recording slight variations from one site to the other, with no significant differences (P> 0.05) across the study stations and distances. Electrical conductivity concentrations ranged from 562.00 - 982.33μS/cm, with the highest concentrations recorded at 0 - 50m, whereas concentrations were lowest beyond 100 m. Significant increased concentrations of heavy metals (Fe, Mn, Zn, Cu, Cr, Pb, Ni and V) were reported when compared with the control. The bacterial count (F= 7.527,df = 3) and fungal count (F=5.749, df = 3) of soil sample did not show a significant difference (P > 0.05) between the test stations and the control station respectively, although the mean ranks were highest in the control station.

The Empirical Analysis

This article examines, theoretically and empirically, the impact of municipal waste management policies such as unit pricing and recycling on the demand for residential municipal solid waste disposal. Using a unique cross-sectional data set for 149 municipalities from five New Jersey counties, the empirical analysis estimates the demand for household municipal waste disposal. In the presence of recycling opportunities, the estimated demand elasticity is higher than that found in previous studies. This suggests that bag or tag unit pricing programs, combined with curb-side recycling, will improve social welfare and reduce municipal expenditures on waste disposal services. Mandatory government-supported recycling programs throughout New Jersey afford an opportunity to consider both the direct impact of recycling and the interaction between unit pricing and such recycling programs on municipal waste disposal.

The Impact

The rising quality of life and high rates of resource consumption patterns had an unintended and negative impact both on the urban and rural environments and even on indigenous communities. Cities are now grappling with the problems of high volumes of waste, the costs involved, the disposal technologies and methodologies, and the impact of wastes on the local and global environment. This study is entitled Solid Waste Disposal Practices of the Atis (Aetas) of Boracay. The study was conducted to identify the Solid Waste Disposal Practices of the Atis in Boracay in terms of method of garbage storage and their methods of garbage disposal. It also seeks to identify activities/ programs implemented or practiced in the community to minimize improper waste disposal practices of every household in the community. The researcher to gather the information needed to be utilized a survey questionnaire. Interviews with 25 households and observations were conducted to further validate the authenticity of the data. Findings revealed that in terms of household garbage storage the respondents stored their garbage in a plastic bag, in an open container, and others pile it in the yard especially those biodegradable wastes. Concerning their garbage disposal practices, every household practiced proper segregation of waste. For their food waste, they put it in basket compost, while plastic containers, bottles, metals, and glass were segregated properly and disposed to a dumpsite through garbage collection. Trashes such as papers/cardboards were used for cooking by the Atis. Yard trimmings were used as compost as organic fertilizer. A once a week community cleaning is conducted by the Atis to maintain the cleanliness of their community where proper segregation of wastes was also monitored by the community organizer. In partnership with the Department of Agriculture Atis of Boracay were trained on basket composting to manage their biodegradable wastes. They were also guided by the policy of the Local Government Unit of Malay on proper wastes disposal.
