In Japan, landfill leachate is managed by a comprehensive fail-safe system that does not depend on a single measure but combines diverse measures as below. Reduction of rainwater infiltration into waste layers : prevention of rainwater infiltration by covering the waste layers with soil and installing structures such as sloped surfaces with rainwater
In Japan, the incineration process has been considered the primary disposal system for solid waste for the past century, and landfill was only a secondary system, mainly used
Japan has a set of specific challenges when it comes to dealing with its waste. The biggest of these is lack of land suitable for landfill. In the 1960s it became clear that, with it''s rising population, Japan would have to
Our empirical results show that a spatial concentration of landfill sites persisted in Japan from 1992 to 2012. Economic factors, such as land price, industrial-waste volume, and the industrial structure, play a significant role in the location patterns of landfill sites managed by private companies.
As Japan''s landmass is limited and finding landfill disposal sites is difficult, we have developed a system to collect and transport waste, process it through intermediary
Coastal landfill sites account for only 2% of the total number of disposal sites in Japan but receive 28% of the waste produced because of their relatively large capacity (Inui and Katsumi, 2019
When the landfill in Osaki, in the southwest of Japan, reached capacity, an incinerator was the logical next step. Instead, the town decided to get serious about recycling. Ahead of International Day of Zero Waste, marked on 30 March, Kasumi Fujita, a town councillor committed to Osaki''s low waste policies, tells UN News what inspired her.
In Japan, though, where landfill space is at a premium, considerable thought goes into how to categorize and discard the various types of waste produced in homes and businesses.
This study investigates the spatial concentration of waste landfill sites in Japan over two decades. Using a unique dataset of 2164 industrial-waste landfill sites from 1992 to 2012, we find
Since incinerator ashes, molten slags and other residues are generated through such treatment processes, their proper landfilling has been an important
Waste disposal. Garbage in Japan (ごみ, gomi) is generally separated into burnable, non-burnable and recyclable items. At least two kinds of litter boxes can, therefore, be found in most households and public places. The exact definition of what is burnable, non-burnable and recyclable depends on the municipality and the waste treatment plant
Even though the volume of final waste disposal declined, Japan is facing a shortage of landfill sites as the remaining capacity of landfill sites is decreasing. Measures to reduce waste
The Japanese guideline for municipal solid waste (MSW) landfill was revised for the first time in nearly 10 years. This permitted the introduction of various changes in the philosophy associated with municipal solid waste (MSW) management. The focal points of the revision were a review of the criteria for site design and operation
The amount of landfill waste decreased 5.9% from 2020, and the recycling rate slightly decreased. Landfill waste: 3,420,000 t (decreased 5.9% from 3,640,000 t in
By Tim Hornyak. Special To The Japan Times. Feb 18, 2017. On a windswept island in the middle of Tokyo Bay, a small mountain rises above the waves. A few seagulls and crows swoop above the brown
In fiscal year 2022, the number of remaining years with possible landfill waste disposal in Japan reached 23.4 years, an increase from the 19.3 years calculated in the fiscal year 2013. Premium
The amount of landfill waste decreased 1.4% from 2021, and the recycling rate slightly decreased. Landfill waste: 3,370,000 t (decreased 1.4% from 3,420,000 t in 2021) Waste reduction rate: 99.1% (99.1% in 2021)
This paper presents selected issues of geotechnical and geoenvironmental engineering in waste landfills in Japan. Due to the limited available land space, there have been efforts in constructing and operating the coastal and offshore landfills, which are expected to provide the opportunities of proper waste management as well as the new
Waste landfill leachate (or landfill leachate) refers to polluted water in which various substances from waste are dissolved. Rainwater that falls on landfill sites becomes
The amount of landfill waste decreased. On the other hand, remaining landfill capacity expressed in terms of years increased. As of March 31, 2021; Remaining landfill capacity: 99,840,000 m 3 (slightly increased 0.3% from 99,580,000 m 3 in 2019) 4.

Tight landfill space has long been a serious issue in Japan, and reducing landfill disposal has been a priority. Incineration has become the main means of reducing the amount of waste sent to landfills in Japan, which is why the landfill disposal rate is lower than in European countries.
Of even greater concern is the fact that the landfills emit methane, a greenhouse gas that is 28 times as powerful as carbon dioxide (according to the IPCC''s Fifth Assessment Report). Waste-to-energy
This article focuses on the historical development of landfill technology since the beginning of the nineteenth century in Japan. The regulations and guidelines that form a framework for the technology are reviewed, and the historical background and the current state of Japanese municipal solid waste (MSW) management are described. Through the
Jun 18, 2024. In 2021, the volume of municipal waste disposed at landfills in Japan amounted to approximately 340 thousand metric tons. Figures indicated a downward trend throughout the past decade.
Our empirical results show that a spatial concentration of landfill sites persisted in Japan from 1992 to 2012. Economic factors, such as land price, industrial-waste volume, and the industrial structure, play a significant role in the location patterns of landfill sites managed by private companies. Interestingly, this relationship has been
If Japan continues to generate over 40 million tons of general waste per year, all of its landfills may be filled up in around 20 years.
The result is that system does not just work well, it is also highly profitable: Japan''s reuse and recycling economy was worth £163 billion in 2007 (7.6 per cent of GDP) and employed 650,000 people 6. The lessons for Europe are that governments need to help design circular systems, so that businesses can design circular products and services.
The amount of landfill waste decreased 4.2% from 2019. On the other hand, the recycling rate increased. Landfill waste: 3,640,000 t (decreased 4.2% from
Waste generation per person per day in 2019 was 918g, which has declined 0.03% from 919g in 2018. For the amount of waste ditching, amount of municipal and industrial waste and final disposal amount have been abated since the 1900s. Within 10 years, 30 million tons of industrial waste and 6 million tons of municipal waste have been
Currently, Tokyo has only one operating landfill – Central Breakwater Landfill. The largest amount in the landfill was incineration residue, followed by
According to the Japanese garbage disposal system, its residents must separate their garbage into 4 main categories: Type of garbage. The frequency of collection. Materials. Examples. Burnable garbage. Twice per week. Most household garbage, including things made from paper, fabric, rubber . Kitchen waste, paper scraps, .
Similar to landfills in other countries over the last century, about 70% of MSW landfills in Japan were built into mountainsides using the natural space between ridges to limit land usage (Tanaka
Leachate samples were taken from seven different landfills and concentrations of brominated flame retardants (BFRs), i.e. polybrominated diphenyl ethers (PBDEs) and tetrabromobisphenol A (TBBPA), were quantified. Leaching characteristics of BFRs, especially factors affecting leachability, were clarified to obtain basic information
Still, all this burning produces exhaust fumes that contribute to climate change, while Japan''s reliance on burning its waste fails to put the "3Rs" – reduce, reuse, recycle – at the heart of its waste strategy.
The Japanese guideline for municipal solid waste (MSW) landfill was revised for the first time in nearly 10 years. This permitted the introduction of various changes in the philosophy associated with municipal solid waste (MSW) management.
