LOW - COST BIO - ABATEMENTOF POLLUTION

Mrs Almitra H Patel, MS MIT

Member, Supreme Court Committee

For Solid Waste Management

waste avoided is money earned
WASTE AVOIDED IS MONEY EARNED

Pollution prevention saves inputs:

Reused electroplating wash saves $$$

Nirula milkshakes from 1st icecream rinses

Pollution prevention at source is good.

Better still is effluent treatment

at the end of each process step.

avoid mixing your wastes
AVOID MIXING YOUR WASTES

Single wastes are far more

cheaply and effectively handled

than combinations,

e.g. in canteens or quarters,

* food wastes can be composted,

* “dry” wastes can be recycled.

Road dust collected with garbage

makes both wastes useless.

use un mixed wastes creatively
USE UN-MIXED WASTES CREATIVELY

Cigarette filter waste for moth-proof boards

Carrybags in bitumen IMPROVE road quality

but needs changed tender-specs to take off

Change sick firms nearby into common baling/recycling units, on APGBP model

minimise liquid wastes
MINIMISE LIQUID WASTES

Mixing liquid wastes can give a problem end-product

Neutralised streams have high TDS and salt content

Salty discharges can destroy

farmland and lakes.

garbage can be your friend
GARBAGE CAN BE YOUR FRIEND

Excel Industries bio-remediates its toxic effluents on city waste :

Endosulfan-tainted effluent is used on aerobic wind-rows

First used at 3% dilution,

then stage-wise upto 30% strength.

Ask Mr Ganesan in Hyd at 98480-52725,

or acs@excelind.com for help

avoid runoff into water bodies
AVOID RUNOFF INTO WATER-BODIES

Try high-rate transpiration plantations

e.g. casuarina 5’ x 3’ apart at Puri STP

Coconut plantations are salt-tolerant

Salt-loving salicornia grass for hi TDS

try low cost rootzone methods for non toxic effluent
TRY LOW-COST ROOTZONE METHODSfor NON-TOXIC EFFLUENT

At IGIDR, sullage is sprinkler-fed

to canna - beds surrounding a

collection sump with perforated walls.

Odourless water is used for gardening.

Try this with salicornia or beach plants for salty effluents

recycle what is left
RECYCLE WHAT IS LEFT

Partly-treated water can be re-used for toilets, floor-washing, gardening:

Micro-bubble aerators for quick

oxidation can be decorative fountains

like Calcutta 7-Star hotel’s venturi aerators

Solar evaporation can give pure water for condensers

RO=Reverse Osmosis can pay for itself but the brine produced must be planned for.

use nala gardens to treat run off en route to lakes
USE NALA - GARDENS TO TREAT RUN - OFF EN-ROUTE TO LAKES

Waste-water treatment can be

both beautiful and functional.

Poplar tree bark stores

nitrates and nitrazines

One fern can absorb arsenic,

another for traces of mercury.

nature has the answers
NATURE HAS THE ANSWERS

Tomato roots absorb lead, copper, zinc

Mustard shoots hold lead, copper, selenium (but must be incinerated)

Sunflowers thrive in radioactive

enivronments, and somehow

reduce harmful emissions.

All this works for TRACE QUANTITIES!

remember everything in moderation for your own health or nature s
Remember : Everything in Moderation.For your own health or nature’s,

PREVENTION

IS ALWAYS

BETTER THAN CURE !!

lakes can be bio cleaned
LAKES CAN BE BIO - CLEANED

Thane lake was cleaned up using

mud-balls with bio-cultures + enzymes.

E M = Effective Micro-organisms is a

Japanese bioculture working well to

reduce odours and BOD in waste-water

canals, solar ponds, septic tanks.

lakes can be bio desilted
LAKES CAN BE BIO - DESILTED

Lake-Restorer TMdeepened a US lake

using a floating-doughnut island of

long-rooted water-plants and an

‘air-lift’ pump to bring organic silt up

past the “fixed-film bioreactor” roots.

See www.oceanarks .com

some success stories
Some Success Stories:

12 Restorers in a 36000 sq m treatment lagoon at Tyson Foods Maryland, for 5000 cu m per day.

Lake at Four Seasons Resort in Kona, Hawaii.

$ 1 Million project for a highly polluted canal in Fuzhou city, China

do yourself and your city a favour
DO YOURSELF AND YOUR CITY A FAVOUR

LEND A HAND !

Sponsor a pilot clean-up at a lake.

cetps often invite trouble
CETPs OFTEN INVITE TROUBLE

Replace Akbar’s milk-collection model with Amul’s:

Pay-by-pollution-level pricing.

“Dilution” can be deadly !

Chrome effluent + sewage at Kanpur’s

UASB = toxic Cr-6 sludge in open dumps

locals must see benefits and monitor cetps if not
LOCALS MUST SEE BENEFITS and monitor CETPs. If not :

NIMBY = Not In My Back Yard, or

BANANA = Build Nothing Anywhere

Near Anybody!

Build enviro-costs and Timetable into

product pricing. If not,

“Best” will drive out “Good”, as in TN

anticipate the future
ANTICIPATE THE FUTURE

Polluter-Pays is here.

EPR and LCA are coming soon :

Extended Producer Responsibility +

Life Cycle Analysis.

Think “developed”, not “developing”.
