MEASURES TO PROTECT ECOSYSTEM
INTRODUCTION OF ECO-FRIENDLY TECHNOLOGIES
Use of biofertilisers may be encouraged for controlling pests.
Forestry may be adopted as forests help to restore the ecosystem
Use of chemical fertilisers and pesticides may be minimised.
Renewable energy like solar and nuclear energy is used
Indigenous practices may be adopted to control the destruction and improve the quality of ecosystems
DISPOSAL OF WASTE
Different treatments which are given to the waste for avoiding environmental and health hazards
Segregation of waste
Biodegradable wastes can be converted into manures
Non-biodegradable
Recyclable waste
Toxic waste
Soiled
Process of dividing the wastes with different categories
Waste management
Helps in conserving the natural resources through the recycling of waste materials
Helps in preventing the spread of infections diseases through proper treatment of hazardous wastes
Helps in checking the environmental pollution
2. DUMPING
Designed to reduce or eliminate the amount of hazardous materials seeping from the fill
Groundwater monitoring system
Method of disposing the refuse on land, without creating hazards to public health or safety, by utilising the principles of engineering
3. COMPOSTING
Natural process in which biodegradable materials are decomposed by microbes and converted into manure
Aerobic Composting
Anaerobic Composting
Benefits
Reduction in the space required for landfill
Reduction of Quantity waste- householder
Conversion of organic waste into valuable end products
Recycling of organic materials and nutrients
Reduction in the use of fertilisers and polluting weed-killers
4. DRAINAGE
Removal of surface or subsurface water from a given area by natural or artificial means
To maintain a clean and hygienic environment
To collect the waste water for proper treatment
To prevent flooding during monsoon
Waste- water drainage
Storm-water drainage
5. TREATMENT OF EFFLUENTS
Effluents can be biologically detoxified if they have little or no heavy metals
Primary discharge
Secondary treatment
Tertiary treatment
