RESOURCE REUSE BY DESIGN

FOR A

SUSTAINABLE FUTURE

CONSTRUCTION WASTE GENERATION….

Central Pollution Control Board has estimated current quantum of solid waste generation in India to the tune of 48 million tons per annum of which waste from Construction Industry accounts for 25%. Management of such high quantum of waste puts enormous pressure on solid waste management system.

RESOURSE REUSE-THE URBAN POOR THE WAY

RESOURSE REUSE –ROCK GARDEN CHANDIGARH

REDUCE….REUSE….RECYCLE

• REDUCE – Debris Generation on site

• REUSE – Debris generated on-site / Use salvaged M aterials

• RECYCLE – Use Materials with a Recycled Content

Approach to Resource Reuse involves:

• Separation of Debris at source

• Preparation of separated fractions for reuse

• Reuse on site

• Reprocessing and remanufacturing

APPROACH TO RESOURSE RECOVERY- SEGREGATION OF DEBRIS

REUSE OF CONSTRUCTION DEBRIS ON SITE

Broken bricks used in Terrace-Koba Temporary Shed from Plywood waste

Pinewood from crates used in False Ceiling China Mosaic on terrace from Broken Tiles

RESOURCE REUSE – BY RECYCLING DEBRIS….

RESOURCE REUSE – REFTROFITS & ADAPTIVE REUSE

Heritage Hotels are a Prime example of Reuse of Existing furniture and

Adaptive Reuse of Structures

CREATIVE USE OF SALVAGED MATERIALS- Challenge for Architects…..

World Resources Institute Office, Washington D.C.

Cafeteria Chairs made from seat-belts of junked Cars.

manufactured by Persing Enterprises

Reclaimed wood, that would otherwise have gone to landfills, used in the reception area and staircase handrail

CREATIVE USE OF SALVAGED MATERIALS- Challenge for Architects…..

Kohinoor City Hospital, Mumbai

Steel and wood salvaged from the demolished Kohinoor Mills Building extensively reused in the new Hospital

Salvaged steel reused after testing for structural integrity

Wood reused for making door frames

� The Project Team identified vendors/recyclers from whom 10% of the

Materials was bought, refurbished and reused.

Reclaimed Wood- used in Partitions & False Ceiling Framing

Furniture- Bought from Reseller, Refurbished, Reused.

Bamboo Flooring- Rapidly Renewable

Reclaimed Staircase- Resource Reuse

China Mosaic Resource Reuse –(Reuse of Broken Tiles)

MDF used in the Paneling – 80% recycled content

Materials with recycled content – 25.5% by value of the total materials cost for the Project

LOCAL MATERIALS

The Use of Local Materials

• Saves Transportation Energy

• Supports the development of Local Economy

• Gives the Interiors a Character and Individuality

Mosaic Tiles with red oxide manufactured 70 km from the site,

stone used for masonry quarried- 50 kms from the site

Tiles manufactured locally,

Wood available from within 100 km,

Bricks manufactured 10 kms from the site

Marble- flooring in Gujarat

LOCAL MATERIALS – Kohinoor City Hospital, Mumbai

Bricks used in Masonry, manufactured in Bhiwandi- 65 km from the site

Kohinoor Hospital, the first LEED- Platinum

Hospital in Asia

Cement, manufactured in Chandrapur, 200 Km from the site

Glass DGU by Sejal-Tuf at Thane, 15 Km from the site

Gypsum, ceiling and boards, manufactured at Wada, 90 km from the site

Grey Mosaic tiles sub-flooring, manufactured at Wada, 90 km from the site

Workstations used, manufactured by Jasanis, 10 Km from the site

WOOD – A SUSTAINABLE MATERIAL?

Wood has a Wide spread use in Construction

Certified Wood

• Environmental

– Reduces impact on forestry

• Destruction of forest, loss of wildlife

habitat,

• Wood – sustainable resource

– Renewable, biodegradable, non-toxic,

energy efficient & recyclable

• Community

– Responsive forest management

WOOD – SUSTAINABLE USE

Salvaged wood (Barn doors reused as Office doors)

Composite wood, from wood waste, agri-fibres etc. Urea formaldehyde free

Bamboo Flooring using Sustainably harvested Bamboo. Bamboo replenishes in less than 5 years

WOOD – SUSTAINABLE USE

EICHER- VOVLO HQ – GURGAON- USE OF RAILWAY SLEEPER WOOD

Conclusions…….

RESOURCE REUSE

• Segregate debris at source

• Reuse debris generated on site within the site

• Find Creative ways to Reuse salvaged Materials

• Encourage the Use of Local Materials

• Specify Materials with a Recycled content

• Careful and Educated use of Wood

TARGET….. OPTIMIZED CARBON FOOTPRINT THROUGH DESIGN
