The issue with tile resource depletion

Tajimi City, a place that has been famous since ancient times for producing ceramics such as Mino pottery, has long boasted about being one of the leading producers of tile inside Japan. As a result of a sluggish economy and the closure of mines due to clay depletion, the development of alternative raw materials that do not depend on natural materials has become an urgent matter.

Japan's disposal situation

As of March 2018, there are 1103 waste disposal facilities and 1651 final disposal sites in Japan; furthermore, the country has the most disposal facilities and final disposal sites in the world. It is said that up to 70% of the world’s incineration sites are in Japan. Due to Japan having such a small land area, “disposal of garbage = burning” has become the mainstream. At the same time, it is also said that because the country discharges a large amount of trash, Japan also has some of the world’s best technology to help reduce the amount of garbage. The foremost leading technology is the melting furnace.

SDGs and growing environmental awareness

In September 2015, all United Nations member countries (193 countries) decided to protect our planet by eliminating extreme poverty, inequality and injustice over the next 15 years in order to realize a better future; this plan, which was adopted by the United Nations, was named “Agenda 2030”. This plan is part of the “Sustainable Development Goals”, which is often referred to as SDGs. In addition to challenges that were not fully addressed within the Millennium Development Goals, and by addressing 17 goals and 169 targets, such as the serious environmental issues discussed at Rio + 20, SDGs are an epic challenge to realize a world where “no one is left behind”.

The melting furnace

The melting furnace is a disposal processing method that melts, reduces, and detoxifies combustibles, non-combustible and bulky wastes from households, glass waste, metal parts and sludge from factories, ash (cinders) emitted from incinerators, as well as infectious and medical-related waste from hospitals. This is done at extremely high temperatures between 1300℃ and 1700 ℃. Due to high-temperature melting, dioxins are hardly generated. Molten slag, a black, glassy substance that has been detoxified, is emitted after melting. However, this molten slag is recycled as roadbed material or a source of concrete.

The advantages of melting

Operating expenses and installation costs compared to the incinerator will end up being higher; however, dioxin measures are reliable, and there is also a superiority of recycling emitted materials as raw material. Instead of using incinerators, many places are being introduced to the melting furnace. This trend is predicted to continue in the future, mainly because there are few remaining years at final disposal sites, and recycling is being sought out as much as possible.

Our company’s highly recommended melting furnace: Kubota rotary surface melting furnace (KSMF)

[Merit] Waste plastic becomes fuel!

Marine plastic is becoming a worldwide problem. KSMF is the only melting furnace that can handle plastic as fuel. By taking 30% of plastic among all submitted waste, it is possible to perform melting without using fossil fuel. To solve the plastic waste problem, we believe that this is the most effective method

Molten slag tile

Turning municipality waste facilities into raw material factories

Concept: Returning items from municipalities back to municipalities.

We are developing products using molten slag from Tajimi City and Toyota City, which have municipalities with melting furnaces.

Corporate tile waste

Making tiles from industrial waste and using industrial waste that is in need of treatment at a major company as a raw material

Concept: Return items from companies back to the companies

We carry out product development by using the industrial waste from companies.

Example: crushed and broken glass

Example: waste ceramic material that contains organic matter

Example: soot and dust emitted from a biomass power generator

* Biomass power generation: a system for generating electric power by burning organic matter

Future outlook

Aiming for full-scale production through stages of demonstration experiments!

Step 1 : Prepare a mass-production system

By taking advantage of the power of information and the personal connections within trading companies and in cooperation with local manufacturers, we establish a system for mass production in two types of manufacturing methods

Step 2: Recycle household waste from cities in cooperation with local governments

First of all, Tajimi City and Toyota City are making achievements, and these achievements are being expanded countrywide.

Since tiles with different textures depending on the region can be created, it is possible for us to appeal to environmental cities through our creative tiles.

Step 3: Recreate tiles from waste made by major manufacturers

We collect the waste materials that were in need of disposal and return them to the manufacturer as tiles to help promote CSR.

Using crushed liquid crystal glass as raw material

Step 4: Melting contaminated soil from the Fukushima nuclear power plant and reviving it as tiles

During the melting process, toxic substances such as cesium and dioxin can be removed, so the contaminated soil in Fukushima can be melted and contributed to the reconstruction of the region with safe tiles that are made within the city.

Contaminated soil still packed in untreated flexible container bags

Step 5: Export the technology to developing countries and build a recycling system.

We export technology as a set of melting furnaces and tile factories to developing countries with waste disposal problems, create a recycling-oriented society and jobs, and contribute to regional development.
