Construction and demolition waste recyclingAnand Vallala
Now a days as the construction is increasing the demolition waste from the buildings is also increasing. We have to increase the usage of waste materials and to help for the future generation.
Construction activities generate millions of tonnes of Construction and Demolition (C&D) waste materials each year. These materials contain a lot of reusable materials. If not properly managed, they will become wastes, a burden to the society, which will be extremely expensive to handle and will occupy precious landfill space.
Now even for small projects it has been made mandatory to use Ready mix concrete or compulsory use of Batching plant. However, except for large projects and some industrial projects, Demolition of structures is not yet mechanised. This waste is also affects the air, noise pollution in the form of releasing dust and noise respectively.
Recycling can turn the waste materials into usable products, which can help conserve our natural resources for our next generations and for the sustainable development of the society. In the recent years, C&D waste management issues have attracted the attention from researches around the world.
The ultimate aim is to create the awareness among the Civil Engineers is to do the research on this topic and to reuse these materials.
Main points of this PPT:
• An overview of the concept on Waste management.
• Brief description on “Recycled Concrete Aggregates”.
• Waste reduction and Reuse.
• Demolition techniques.
• Use of proper Waste Management plan.
Concrete is a major waste in construction Industry. It needs to be recycled to make a waste free environment. So how concrete is recycled, which type of concrete can be recycled, where it can be used is mentioned in this ppt.
Construction industry is one of the biggest sector in India with increasing demand. We need to take certain actions and precautions on site to reduce construction waste. Metro cities like Pune, Mumbai and Bangalore etc. are most congested cities. So, the need of flats, apartments, row houses etc. is increasing with higher rate. We need to demolish the existing old structures and build new structures to have the maximum space for environmental purpose. So, there is increasing in demolition waste as compared with construction waste.
There should be certain provisions for the checking of this waste management cycle to prevent its impact on environment. Construction and demolition waste can be classified into 2 components; major components include cement concrete, bricks, cement plaster, steel from RCC, doors & windows, roofing support systems, rubble, stones, timber etc. and minor components includes conduits, GI pipes/Iron pipes/Plastic pipes, electrical fixtures, panels, glass etc.

Recycle material used in road constructionpavan bathani
As the world population grows, so do the amount and type of waste being generated.Many of the waste produced today will remain in environment.The creation of non decaying waste material, combined with a growing consumer population, has resulted in a waste disposal crisis.
One solution to this crisis lies in recycling waste into useful products.
It is try to match society need for safe and economic disposal of waste material with highway industry need for better and more cost effective construction material.
As replacement for fine aggregate in concrete, plastic and e-waste was suggested based on experiments conducted and theoretical data from publications.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.
"Understanding the Carbon Cycle: Processes, Human Impacts, and Strategies for...MMariSelvam4
The carbon cycle is a critical component of Earth's environmental system, governing the movement and transformation of carbon through various reservoirs, including the atmosphere, oceans, soil, and living organisms. This complex cycle involves several key processes such as photosynthesis, respiration, decomposition, and carbon sequestration, each contributing to the regulation of carbon levels on the planet.
Human activities, particularly fossil fuel combustion and deforestation, have significantly altered the natural carbon cycle, leading to increased atmospheric carbon dioxide concentrations and driving climate change. Understanding the intricacies of the carbon cycle is essential for assessing the impacts of these changes and developing effective mitigation strategies.
By studying the carbon cycle, scientists can identify carbon sources and sinks, measure carbon fluxes, and predict future trends. This knowledge is crucial for crafting policies aimed at reducing carbon emissions, enhancing carbon storage, and promoting sustainable practices. The carbon cycle's interplay with climate systems, ecosystems, and human activities underscores its importance in maintaining a stable and healthy planet.
In-depth exploration of the carbon cycle reveals the delicate balance required to sustain life and the urgent need to address anthropogenic influences. Through research, education, and policy, we can work towards restoring equilibrium in the carbon cycle and ensuring a sustainable future for generations to come.

5. Waste generated from construction industry
Inert material
e.g., rocks, concrete,
bricks, stone, earth.
Non inert material
e.g., plastic, packaging
waste, paint
On site waste sorting
• Sort and segregate inert and non-inert materials
• Sort and segregate materials such as paper, plastic, timber,
metals, masonry, concrete and excavated soil
6. Concrete
• Concrete is a
mixture of sand,
cement, aggregate,
water, & admixtures
• Benefits of reducing
of Concrete waste
– Reduce cost of aggregates
– Reduce disposal cost
– Environmental degradation
prevented
– Reduce consumption of
natural resources
– Life span of landfill area will
increase
• Disposal method at CHARUSAT campus
– Due to parallel projects simultaneously
going on so waste generated due to
concrete is generally used as a filling
material and sub base layer of pavement
construction.
– Due to use of Ready mix concrete waste
generated due to concrete reduced
considerably
7. Stone/Marbles
• How the waste is generated
? The stone/marble which
came from the quarry was
not of a perfect size and
shape which is likely to be
used in work, so we have to
cut the stone/marble in
desired shape and size as per
our requirement.
After cutting the excess
portion has no further use
hence waste is generated .
• Reuse of the waste
– In most cases the stone waste is
used as filler material in road
construction part.
– The marble waste sometimes
used in terrazzo flooring.
If there is no reuse of stones/marbles
they are dumped/sell to other
agencies.
8. Timber
How the Waste is generated?
•Timber is generally used as
framework for building concrete
structures, with passage of time it
become soft due to contact with
moisture of concrete.
•Shape & size of timber somewhat
change which is not proper to use
as framework, so it has no further
use hence waste is generated.
Reuse of the waste
– It is mostly crushed into chip &
used as fuel.
– It can be utilized to manufacture
wood-chip concrete by injecting
cement grout into voids of
compacted wood-chips in moulds.
– Wood-chip concrete can be used
as building material.
9. Sand
• How the waste is generated ?
1. The sand which came from the
quarry was not of a perfect size
which is likely to be used in
work, so we have to sieve as per
our requirement.
2. After sieving the remaining
sand has no further use hence
waste is generated.
• Reuse of the waste
1. In most cases the sand waste is
used in road construction.
2. After the use of remaining sand
there is some amount of sand is
mixed with soil so that sand is
useful for garden decoration.
10. Steel
How steel waste generate ?
1. Most of steel waste is generated
during demolition around 70%
to 80% of all steel waste.
2. Remaining parts of steel rode
during construction stage
3. Due to corrosion
4. Waste in terms of bent Nail
5. Small Pieces of G.I. pipes
Reuse of steel waste
1. For making of stirrup
2. For hidden structure use waste
pieces
Suggestion Given by us
1. Collect at one place & sell for
income.
11. Brick
How waste generate?
• A brick is a block or a single unit of a
kneaded clay-bearing soil, sand and lime,
or concrete material, fire hardened or air
dried, used in masonary construction
• The Brick Waste is generated in the form
of Bats and Small Pieces
• While loading from the manufacturing
unit to the unloading at the Site , there is
possibility where the Bricks get broken
and turn into bats and the small pieces
• Reuse of the waste
Broken and discraded Bricks can be
used as consturuction infill or as aggregate
for non-structural concrete.
Crushed brick & roof tiles are the
bulk of demolition waste which were
earlier being dumped in landfills , now
they can be recycled into mortar plaster &
building blocks.
12. Glass
How the Waste Generate?
• Glass Waste is generated in
the form of broken pieces.
• While demolition and
restoration work of any
stucture the glass waste is
generated.
• There is less chance of Glass
waste while any work as care
is taken to remove and place
the Glass , but somehow due
to improper holding and the
handling of the Glass, the
waste is generated.
• Reuse of the waste
• Generally in India the Glass
waste is dumped without taking
any care but the site we visited ,
at that place the authority takes
special care for the disposal of
the Glass which is being sold to
the Junkyard People for the
recycling the Broken , Damaged
Glass.
13. Plastic
How plastic waste Generate?
1. Cement bag
2. Cover material for flooring
3. Pieces of pipe
P.O.P.
How p.o.p. waste generate?
1. During ceiling work
Ceramic
How it generate?
1. During transport
Reuse of plastic waste
1. Joint the plastic bags of cement & use as
curtain for protection of neighbour
property
Reuse of p.o.p. waste
1. It only use as filler
Reuse of it
1. For flooring of terrace as a china mosaic
14. The important initiatives sited are:
• Promoting separation of C&D waste at source
• Promoting recycling
• Band on land filling of C&D waste
• Developing market for recycled products
• Production of concrete bricks and paving blocks
• Guidelines for using C&D waste
• Developing designs which facilitate ‘deconstruction’ instead
of outright demolition
15. Conclusion:
• It has been established that materials & components from
demolished buildings are being reused for new construction
works as well as renovation projects, especially by low-income
communities in developing countries like India.
• In developing countries most of the demolition rubble is
dumped, the developed world has now started to recycle it into
aggregate for non-structural concrete.
• It is hoped that recycling waste material for use in the building
will cut down costs of producing new raw materials thereby
reducing consumption of natural resources like energy &
reduces usage of landfills.
