"E" is a keyword in the recycling society"E's" motto is, "To produce a product Desirable For everyone;customers, manufacturers, discharge producers and the Earth.
Earth, Ecology, Environment, Education, Energy, Economy etc. - inthe recycling society, where Natureand humans coexist, thekeywords start with "E".
Across the field and in various situations, places and scenes, it is"E's" idea to build a network which links these "E's" organically, and to aim for arecycling
society.
"E's" philosophy is to cherish to produce the product comfortably, not only for the sake ofthe development of the company, but also for the population and the Earth.

The commitment of using the Non-Firing Solidification Technology
無焼成・無排水・無廃棄We have special patent technology called "the Non-Firing Solidification Technology".
This is a reclaiming technology, using various kinds of waste, to produce clean bricks androadbed materials without baking. This is a low environmental impact recycling technology,
that is carried out in seven plants within Japan.
On the other hand, in other Asian regions - China and India in particular, large economic
growth is occurring, which is producing mass quantities of air pollution and waste that isdifficult to manage.
The brick production volume in these areas constitutes approximately 80% of the world's
total volume. Brick production creates large amounts of CO2 waste, which is a significant
factor in global warming, barren land issues and desertification.
The Non-Firing Solidification technology for producing bricks is an ideal form of recycling with regards to resource protection, waste becomes the raw material of the brick, and tocontribute towards the prevention of global warming, the product is not baked.
Now, we wrestle with many national businesses and are aiming to take "E" to "Global E".

Although they are non-fired, they are very safe, high quality and low
price.

Sewer sludge, burned ash, coal ash, ceramics abolishedsoil [ Kira ], molten slag, glass waste and many otherunused resources are utilized, and are regenerated toform a revolutionary brick style block, without baking,using our special slodificaton technology (Patentprocess).
We feel it is important to create materials of soft disposition, that feel like ceramics,
which gives warmth and serenity to the cityscape.

Feature◆ resource conservation

80% of the raw materials are made up from several
kinds of by-products from other industries, which
result in absolute zero emissions. It is possible toproduce strong, stable, durable bricks of long term
quality by utilizing the best mix of raw materials
with their own individual qualities.

Gifu-ken waste recycling
recognition product◆ Circulation type

We reuse the inferior goods which come out of themanufacturing process as raw materials, and also,
because of the non-firing technology, no CO2 orfactory draining watse is created. Furthermore, theproducts can be reclaimed as many times aspossible after use.

preservation commodity◆ Energy conservation

Scrap materials without pretreatment can be used for raw materials, even without-31-

firing. Due to the fact that the fossil fuel is not burnt, excessive processes areexcluded, so the production is energy-saving and cost-saving.
◆ Safety

From the acceptance stage of the raw materials, of course to the finished product,
the process conforms to strict physical properties standards and environmentalstandards. Furthermore, we execute the original released metal content test with
Ph3, which is above and beyond the safety satndards.
◆ Scenery characteristics

The product looks a little like antique bricks, due to the ceramic kneading
technology that is applied, and they will continue to mature attractively over the
coming years of use.
◆ Consideration type

It is suitable for non slippy, comfortable, barrier free sidewalks. Furthermore, inorder to produce good effects on vegetation and the living environment, special EM
ceramics have been added to the raw materials.

The non-fired eco bricks which are produced from industrial waste
Our non-fired eco brick is produced by materials made from industrial waste. To
regenerate various kinds of industrial waste to a brick-like block by "non-firing", "nodisposal", "no drainage" production, which are the low-environmental-load, recycledbricks.

Materials for non-fired eco bricks◆ City rubbish melted slug (general waste incineration melted slug)

Incinerates general home "burned rubbish" to stabilize (shut in) the harmful matter,
which is melted at high temperature (melting) to vitrified slug (sandly).
◆ Sewer sludge ash (feces, urine and other careless drainage waste ash)
There are two types of sewage which are the branch system and the confluence system.

The branch system is the waste water, feces and urine from homes, and the confluencesystem is when the branch system waste and the rainwater that fell in the urban
district flow together. The sludge ash is the sludge, after microbe processing, andincinerated to reduce capacity to minute powdered ash.
◆ Waterworks sludge

beverage service water purification remaining earth◆ Coal ash < fly ash: FA>

coal thermal power burned ash◆ Glass cullet (pulverized glass, such as glass packing container)

Among the glass bottles which are disposed of, mainly from general homes, is glass
which cannot be recycled < shattered bottles of import wine and bottles of cosmetics,
are examples > these are ground into sand condsistency (the cullet).
◆ Paper sludge ash <PS ash > (waste paper, recycling by-product ash)During the processing of waste paper to make the recycled paper, the old ink and clay
-34-

which is contained in the paper, is discharged as sludge. After chemical treatment, thecapacity is decreased by incineration to minute powdered ash.

◆ Minute silica sand < [kira] > (glass ceramics raw materials extraction processby-product )The powdered sand which remains after extracting, from the minerals, the silica sandwhich become the raw material of glass and clay which make ceramics ( the mountainsoil which becomes the raw materials)◆ Quarrying waste soil (remaining soil after extraction of gravel)

It is discharged in the extraction of mountain gravel and mountain sand. There are
two manufacturing methods that discharge them, which are the wet process and thedry process. The wet process is the main discharger of waste.The the gravel and sandis washed and put through the filter press (the dehydrator) to eliminate clay sludge.
(The stone dust which is discharged during the dry process can also be used)◆ Cupola slug (metal industrial waste)This is the slug which is discharged from automobil parts factories. The slug isdischarged by using the blast furnace, which is called the cupola, to discharge the pig
iron (dissolved iron), which is melted with high temperatures to a mud condition thatis removed directly in water, becoming sand condition.
◆ Foundry sand or Cast-metal sand(metal industrial waste)This is the fine sand which is used in order to form cast-metal.
◆ Dam, lake and pond bottom mud (accumulation sludge)

This is the sludge which has sunk to the bottom of dams, lakes and ponds, containing
the organic matter. Its state varies, depending on the surrounding environment.
◆ Waste gypsum (pulverized gypsum board)This is formed when gypsum board from constructive scrap is pulverized to white
powder, to remove paper and rubber, etc and extract gypsum.
◆ Housemanufacturer externalpulverization or sludge)

wallmaterial

rubbish(cementtype

This is the waste produced when major residential manufacturers pulverize theexternal wall and edge materials from the demolition of the original residence, inorder reuse materials of cement type etc.
◆ Bentonite mud (civil engineering works scrap material)-35-

This is the used mud of sealed construction and post construction bentonite (clay).

◆ Volcanic ash

volcanic ash such as Mt. Usu and Fugen peak
◆ Used pearlite

Incinerating pearlite, which is used as an absorbant, converts it to inorganic andmakes it minute powder.
◆ The slaked lime sludge

The slaked lime sludge which occurs at the time of carbide production.
◆ Rock wool (silica calcium) waste

The waste of rock wool heat insulator used in furnace walls◆ Plastic waste, FRP pulverization◆ Construction site outbreak remaining soil

The remaining soil which occurs during construction works and civil engineeringworks◆ Others

In addition, cinder, burning shell,inorganic characteristic sludge, dust, ore occasion,
glass ceramic ware rubbish, plastic waste-36-
