ABOUT ECO-BOARDS

ECOBoards is the new generation MDF fibreboards.

ECOBoards are NOT made from WOOD but uses agricultural fibres, residue or by-products from harvests, a product that is usually burned as a waste problem.

Plastics and paper waste may also be used in these boards.

TYPES OF ECO-BOARDS

Coir – CNSL Board Bagasse-Cement Boards and Panels Arhar-stalk-Cement Boards and panels

Lightweight Sandwich Panels Rigid PVC Foamed and Un-foamed Boards

Bagasse-PVC Boards Coir-CNSL Thermal Insulation Board

COIR CSNL BOARDS

The Coir-CNSL Board is a wood alternative which can be used for surfacing, door andwindow shutters, partitioning, false ceiling, panelling, furniture, cabinets, packaging, etc.

It is a single layer flat pressed class Medium Density Fiber (MDF) Board.

It has low waterabsorption, negligible change in dimensions due to water

absorption, workable with normal wood working tools, paintable, pre-laminable, nailable and screwable

COIR CSNL BOARDS Both the starting materials i.e.

coconut fibre and cashew nut shell liquid are available substantially in coastal areas and are renewable agro-wastes.

Technology is developed at pilot level and ready for transfer.

The technology and product both are patented.

Technology is techno-economically viable as per pre-estimates.

The estimated cost of the board is around 30% cheaper in comparison to

commercially available similar products such as MDF board, plywood, and block board.

BAGASSE-CEMENT BOARDS AND PANELS

The product and process utilizes sugar cane bagasse and ordinary portland cement.

Thephysico-mechanical behaviour of the developed building board passes most of the requirements of general purposes high density board and is cost effective too.

Three layered Single layered board

board with bagasse With Bagasse

ARHAR-STALK-CEMENT BOARDS AND PANELS

Made using fibrous biomass such as Arhar Stalks, Groundnut Shells etc. for the production of composite materials.

Helps in utilizing fibrous biomass and in conserving wood in building and construction industry.

This product can easily be made in rural areas itself since the raw material is substantially available there which will help in low cost housing in rural areas.

LIGHTWEIGHT SANDWICH PANELS

The cellulosic refuse of paper industries are rich in small fibres and can be used to make value added product.

Useful for paper industries as a downstream process.

Used for acoustics, thermal insulation and false ceiling purposes in buildings, partitioning, panelling, thermal insulation and false ceiling with its unique aesthetics.

RIGID PVC FOAMED AND UN-FOAMED BOARDS

These are boards made from P.V.C scrap.

They are used as an alternative for wood.

Cost of production is less. It can be used in low cost housing for partitions, door and window frames etc.

BAGASSE-PVC BOARDS The sugar cane bagasse is used to make the

building boards using PVC as the binder. Used to make door shutters,sanitary fixtures,

pipes, cables, cabinets,

PRODUCTION

The primary raw material for these products is agricultural waste and building scrapSorting of raw material

Breaking the raw materials in to particles and compating

Addition of a poly-urethane binder

Addition of a poly-urethane binder

Compression under high temperature and pressure steam heated hydraulic press

Sizing the sheets and assembly

BENEFITS ECOBoard panels can replace plywood, chipboard, OSB

type 3, multiplex and conventional fibreboards (including MDF, hard-board and soft-board) for a wide range of applications.

Due to the no formaldehyde added resin (NAF) being used, ECO-Board panels have emissions far below the strict E0 European low formaldehyde (LF)

ECO-Boards are suitable for use in environmentally sensitive areas such as

1. schools

2. nurseries

3. children's furniture

4. hospitals

5. public buildings

6. laboratories

7. nursing homes

BENEFITS Moisture Resistance: Unlike traditional

woodbased boards ECO-Boards are extremely moisture resistant and are specified for use in the most strenuous humid domestic interior conditions where dimensional stability and retained strength are of great importance such as Kitchen & Bathroom furniture, skirting boards, mouldings, wall cladding, flooring, etc

Fire Resistantance: ECOBoards are standard >20min fire resistant.

High Strength, Lighter Weight: The High strength to lighter weight ratio of the ECOBoard panels further eases panel handling (manufacturing plant, contruction site).

BENEFITS Screw Tightness: The tenacious screw

holding ability adds flexibility to the choice of fitment hardware that can be used (hinges, brackets, screw types).

Machinable: ECOBoard Bio-Composite Panels are made in a Single Layer process giving homogenous consistency throughout its thickness, similar to MDF. The Single Homogeneous Layer and Its superior internal bond (cross tensile) allows smooth strong profiling and sharp machined edges. Less dust and released toxins allows a cleanier and healthier working environment.

BENEFITS

BENEFITS Cradle to cradle system. Products are of two types, technical and biological. Technical nutrients are strictly limited to non-toxic, non-

harmful synthetic materials that have no negative effects on the natural environment; they can be used in continuous cycles as the same product without losing their integrity or quality.

In this manner these materials can be used over and over again instead of being "downcycled" into lesser products, ultimately becoming waste.

Biological material can however decompose and go back to the soil or the nutrient pool.

Eco-board is one such material which can give directly ack to the nutrient pool after being used.

Hence it completes the cradle to cradle cycle. Life Cycle Analysis shows Carbon footprint is negatif  -

0.618 Co² eqv / kg.

WASTE AS A RESOURCE-A FEW TECHNIQUES Tin sheets are a common material used by most slum

dwellers but has certain short falls. Tin sheets are thin and thus whenlaid flat has less

strength. Thermal conductivity of non insulated tin sheet is high

making internal spaces hot. Non-concealed joints between tin sheets are vulnerable

to climatic conditions mainly leakage during rain.Technique developed:Folded tin sheets are strongerwhen laid horizontal.Roof panels laid in lean-toarrangement helps in betterwater run-off.

Folded tin sheet roof panels can be covered with mud mortar for insulation.

PROJECT

The waste from the university must be substantial.

Considering Anna university and the waste generated.

Forming self help groups with the Surya-nagar slum nearby, involving the local people.

Coming up with innovative techniques with the waste generated.

If possible to look at the workshop in SAP, assess the material value on pulling down and looking at how the scrap can be used.
