� "The band of dry land and adjacent ocean space (water andsubmerged land) in which terrestrial processes and land uses directlyaffect oceanic processes and uses and "vice versa".

� 25% of India's population lives within 50 km of the coastline – 7500Km;more highly populated than inland regions (2.6 times)- urbanisation

� Concentration of sectors – rapid urbanization, industrialization,

Coastal areas

expansion of education, health & tourism services- multiple use/functions, multiple, competing demands-diverse activities - increasingproduction/ diversity of solid wastes- Ecologically/socio-economicallyvery sensitive – fragility – higher degradation of habitats/BD loss

� Lack of integrated sustainability approaches - Inadequate governance -weak resiliency – dumping/burning of un-segregated solid wastes-Solid waste management ?

Mumbai-Geography, demography & Climate

• Financial capital of India - West Coast – 36 km longcoastline - 24 wards. As of 2011, four slums inMumbai larger than Dharavi- once considered as thelargest slum in Asia! Some of them - three times thesize of Dharavi! 8500 million tons of urban MSW/day

• Urban- 4335 Km2; suburabn- 369 Km2 ;The islandcity is now largely free of slums, except on thefringes, like Dharavi in the North, Antop Hill in theEast, Geeta Nagar and Ambedkar Nagar in theSouth and Worli village in the West. The erstwhileSouth and Worli village in the West. The erstwhilesmaller slums in the suburbs have metamorphosedinto contiguous, larger slums. The Kurla-Ghatkoparbelt, the Mankhurd-Govandi belt, the Yogi and Yeoorhill slopes stretching from Bhandup to Mulundflanking the Sanjay Gandhi National Park (SGNP)on the East and Dindoshi on the western flank of theNational Park have all eclipsed Dharavi.

• Tropical wet and dry climate- 61-86 %. humidity-average of 27.2 °C (range -16-33) and averageprecipitation of 2000-2500 mm

MSW MSW -- status in India status in India

• Management of solid waste is associated with the control of

generation, storage, collection, transfer & transport, processing, and

disposal of solid wastes- MSW (management & handling) Rules

2000; BMW (management & handling) rules, 1998 & 2011

• The ever increasing generation of MSW vs. limited HRs/facilities –

privatisation? economics of scale – slums /low density areas?

• Unscientific disposal causes an adverse impact on all components of

environmental and human health ( Rathi, 2006: Sharholy et al., 2005;

Ray et al., 2005; Jhe at al ., 2003 ; Kansal, 2002; Kansal et al., 1998;

Singh and Singh, 1998; Gupta et al., 1998).

• Average for India - 0.5 -0.7 Kg/capita MSW generation/day

• Puducherry – 350 t/day ; Mumbai- 9000 t/day

indiscriminately in the streets and in

drains, contributing to flooding, and

breeding of insect and rodent vectors.

The MSW crisis in coastal areas

• Traditionally, waste in rural India was managed well, as the waste streamswere biodegradable, reusable or recyclable. Escalating production of diverseMSW along with an increase in the generation of hazardous & toxic wastes –MSW/ construction debris thrown on streets; septage on road sides in theoutskirts; open defecation along the coast; BMW mixed with MSW;hazardous with non hazardous; biodegradable with non biodegradable – vsassimilative/absorbing capacity

• Lack of collection/segregation at source &operational inefficiencies,inappropriate technologies -waste collection rates are often lower than 15 percent in most of the cities. More than 50 % (at times up to 90%) of theinappropriate technologies -waste collection rates are often lower than 15 percent in most of the cities. More than 50 % (at times up to 90%) of thecollected waste is often disposed of through uncontrolled land filling andabout 9- 15 per cent is processed through unsafe and informal recycling byrag pickers

• Overflowing landfills- opposition for dumpsites -NIMBY syndrome !

• Degradation /pollution of critical coastal habitats

Page 30: Eco-technologies for MSW Management in Coastal areas - An

Septage Septage –– a misplaced resource!!a misplaced resource!!

• Septage contains plant nutrients such asnitrogen, phosphorus, and in some casesvarying amounts of micro nutrients suchas boron, copper, iron, manganese,molybdenum, and zinc (EPA, 2011)

• Independent septage treatment facilitiesuse processes like stabilization lagoons,chlorine oxidation, and aerobic andchlorine oxidation, and aerobic andanaerobic digestion, biological / chemicaltreatment

• Co-treatment of septage along withdomestic sewage at a sewage treatmentplant; non conventional methods -Improved septic tank/Anaerobic baffledreactors, constructed wetlands

• Industrial fuel, methane & biodiesel,biofertilisers….

TPS is:(1) Collection

(2) Lacto-fermentation,

(3) Addition of charcoal

and vermicomposting,

(4) Incorporation of terra

preta compost into soils.

Page 52: Eco-technologies for MSW Management in Coastal areas - An

Added materialDesign Principals

Charcoal mix:

• Charcoal

• Stone dust

• Finely cut wood

• Some limestone or volcanic soil

Microbial mix:Similar to commercial available effective

microorganisms (EM) mix, but specifically

designed to prepare for vermicompost and

for free!

• Bacillus subtilis, Bacillus mesentericus,

Geobacillus stearothermophilus,

52

• Some limestone or volcanic soil

Wood can be replaced with any

other bulking agent to raise C/N

necessary for vermicomposting.

The mix can be prepared in

advance and stored close to the

toilet (keep it dry!).

Geobacillus stearothermophilus,

Azotobacter croococcum and Lactobacillus

• Available at the Technical University

Hamburg-Harburg (TUHH, Institute of

Wastewater Management and Protection,

aww, Germany) or from the Xavier

University Sustainable Sanitation Center

(Philippines)

To prepare a lacto-fermentation microbial

mix, one can also take an Inoculum from

Sauerkraut liquor.Picture sources: OTTERPOHL (n.y. b); GENSCH (2010 a)
