Lagos vision 2020

Public/Private Participation in Waste

Management(Collection, Transportation, Treatment

and Disposal of Solid)

Development of a functional and sustainable Solid

Waste Management facilities

Lagos population is projected to reach

30,200,000 and generate waste of 21,140ton/day

by 2020 (2006 Census Projection)

Lagos government have developed 15 transfer

stations in the last 6 years

E-waste result from electronic products nearing

the end of their useful life.

Most electronics contains toxic substances such

as:

Lead

Cadmium

Plastics (PVC)

Sources of e-waste

Importation of used electronics

Locally used electronics

Importation of used electronics parts & accessories

Donations from overseas to charity organizations,

academic institutions

Nigeria imports about 500,000 used

computers annually through the Lagos port

alone (Basel Action Network, 2005).

About 25% of the imports are functional used

computers while the remaining 75% is junk or

unserviceable

Newly arrived used phones

Management of e-waste

Sale of reusable and serviceable parts

Repair and refurbishment of used electronics for reuse

Disposal in open dump sites

open burning of irreparable e-waste components to

reduce solid waste volume

Industrial waste refers to any waste produced

during production, storage, distribution of

industrial products

Lagos harbors about 592,000 Industries and

Business at an expected growth rate of 5% per

Disposal and treatment of industrial wastes

Because of lack of functional sewage system raw,

untreated and highly toxic industrial effluents

are mostly discharged freely into open gutters,

drains, streams, lakes and lagoons

Study show that Lagos lagoon alone absorbs

10,000m³ of industrial effluents daily.

Because of lack of adequate monitoring industrial

gaseous toxic wastes are released untreated into

the environment

Most waste problem arise from

inadequate land use planning

lack of adequate implementation measures

Corruption of waste management officials

Lack of awareness of the implications of wastes

Inadequate infrastructure

There is an urgent need for action plans and

training of waste management officers for

monitoring and control industrial waste
