WASTE MANAGEMENT

1
WASTE MANAGEMENT

• Waste Management has several dimensions-engineerin
  g,economic,Geographic,social and management.Its
  basic purpose is to minimise the overall waste in
  a given system.Waste here refers to waste of all
  kinds or resources,but especially the material
  resources which constitute a significant
  portion.To reduce waste we have to maximise the
  use of resources.

2
Classification of Waste

• Waste can be classified on the basis of
  (1)resource wasted(2)origin(3)property
• (4)recoverability.
• Measurement of Waste
• Wastivity Waste(W)/Total Input(I)
• Gross WastivityTotal Waste/Total Input
• Net WasteTotal Waste-Waste recycled within the
  system.Net WastivityNet Waste/Total input.

3
Wastivity Productivity

• Waste is an indirect measure of productivity.If
  wastivity is checked the effect,productivity will
  be improved
• CAUSES OF WASTE.i)faulty planning
  policies,systems and procedures ii)Faulty
  Organisation structure,iii)environmental
  pressuresiv)tardinessv)lack of accountabilityvi)un
  awareness of technological advances vii)non
  responsiveness to automation/computerisationviii)
  wrong specifications,standards,codes

  control xi)lack of proper storage,layout of
  facilities,handling of materialxii) communication
  gaps xiii)faulty work method xiv)less emphasis on
  PPC xv)lax supervision and control xvi)Wrong
  recruitment/selectionpolicies xvii)lack of
  motivation /incentives xviii)poor working
  conditions xix)unsafe practices xx)Poor
  industrial relations xxi)Maintenace failure

• xii)Power failure xxiii)Distribution problems
  xxiv)less attention to waste segregation and
  collection xxv)technological obsolescence
  xxvi)Miscellaneous causes.
• Systematic approach to Waste Reduction
• Waste collection system
• Recycling of wastes
• Waste disposal system(salvablenonsalvable waste)

Management of Surplus and Scrap

• What is surplus?When purchases have been made in
  larger quantities than the usual requirements.
  when operations are suddenly curtailed,when at
  the materials procurement,on a/c of some error or
  miscalculations.When the usual materials are
  remdered useless due to change in materials
  specifications.When the project is completed some
  quantities are bound to be left out.
