“…However, land ll is likely to bring about greenhouse gases emissions, generation of large amount of leachate, and nally environmental pollutions (Ma and Liu 2019). Although incineration could reduce the volume of food waste, it needs a high demand for energy, and the process itself is prone to produce harmful and or greenhouse gases (Liu et al 2019).…”

Biodegradable household garbage contains a large amount of nitrogen which could be used as organic fertilizers to produce organic foods, thus mitigating environmental pollution at the root. However, due to the complex composition of household garbage and its uneven distributions from urban to rural areas, it is not clear how large the biomass nitrogen reservoir is in a certain country or region. Here we took China as a case, systematically analyzed the amount of biodegradable household garbage resources and their nitrogen reservoirs. It was noted that the biodegradable household garbage mainly included food waste, waste paper and wood chips, with the amounts being 31.56, 29.55, and 6.45 million t·a− 1, respectively. Accordingly, the nitrogen reservoirs were 65.31×104, 6.80×104, and 3.81×104 t·a− 1 in China. Regardless of provinces or provincial capital cities, there were significant positive linear correlations between the gross domestic product and the amounts of foods wasted, indicating that China’s fast economic development was at the cost of huge food waste. However, if the food waste were used as organic fertilizers, chemical nitrogen fertilizers would have been greatly reduced. We found that food waste nitrogen reservoir accounted for 86% of the total, with its nitrogen reservoir being equivalent to 11% of the amount of actual absorption for synthetic nitrogen fertilizers (6.20 million t·a− 1) by agriculture plants in the country. Our findings provided a scientific basis for the classification and utilization of biodegradable household garbage, ensuring food security, and eliminating environmental pollution.

“…In Taiwan, six special municipalities and 16 cities and counties cover a large variety of urbanization and settlement characteristics, such as the population areal density and electricity and water consumption, both within the administration boundary and per capita. There are many socio-economic, environmental, and MSW service factors employed to correlate or evaluate MSW systems [15], such as households [16], GDP per capita [17], and recycling rates [18]. Since all human activities require electricity and water consumption, the present study aims to compare the correlation between MSW, population, and utility consumption to identify the most pertinent factors influencing MSW generation.…”

In Taiwan, 3,130,735 t of refuse for disposal and 4,113,808 t of recycled recyclable waste were generated in 2017. The government of Taiwan has been actively promoting a resource recycling program since July 1998. To pursue sustainability and locate waste minimization opportunities, the correlation between utility consumption and population and the quantity of refuse and recyclable waste from municipalities in Taiwan was studied. There are six special municipalities and 16 cities and counties covering a great variety of urbanization and settlement characteristics, such as registered populations, electricity, and water consumption. The above parameters of the municipalities were correlated with the quantities of refuse and recycled urban waste. Residential electricity consumption, overall population, and business electricity consumption were found to be major parameters correlating the generation of refuse and recycled urban waste. Due to their higher levels of business activities, the waste generation behaviours of these six special municipalities are more diverse than those of the 16 municipalities. Due to the discrepancy of the registered population system, the utility consumption values within administrative boundaries can better predict municipal solid waste, (MSW) generation than utility consumption at a per capita. Utility consumption within administrative boundaries is more convenient as a measure to predict refuse and recycled urban waste than other complex social–economic indicators.

“…Some authors analyzed the impact of consumption factors on the generation of municipal solid waste (Liu et al (2019); Lu et al (2017); Mahees et al 2011;Hage et al 2018). The results showed that developing regions generate more waste than developed regions.…”

Econometric Modelling of Solid Waste Generation in Jordan

The objective of this study is to develop an econometric model that might help decision-makers to imply better policies based on the information about key factors influencing the amount of waste generation in Jordan. We found out that the most informative factor is the level of consumption which is correlated with the number of population and gross national income. Consumption culture itself rather than the population growth stimulates waste production. In order to reduce the level of waste generation, it is necessary to move from an unreasonable culture of unrestrained consumption to a reasonable and responsible attitude to the resources of the country and the environment as a whole. It is also necessary to introduce modern waste management methods, develop technologies for waste recycling and reuse.
