ENS 321 Environmental Management in Horticultural Industries (1 + 1)

 

Aim

To impart knowledge on environmental issues in horticultural industries and its management for environmental sustainability

 

Theory

 

Unit I – Environmental issues in Horticulture Industries

Horticultural industries – waste generation - liquid and solid wastes – environmental problems - management

Unit II- Waste treatment technologies - liquid waste

Wastewatertreatment methods – physical, chemical and biological methods – aerobic and anaerobic treatment –Bioreactors -Biofilters- constructed wetland - Recycling treated wastewater for irrigation– Permissible limits for land application

Unit III -Waste management technologies - solid waste

Solid wastes - sources, disposal problems and management technologies - recycling - resource recovery - composting and vermicomposting - quality standards

Unit IV-Waste management in different horticulture Industries

Fruit processing (Mango, Grapes, Papaya etc.) - Vegetable processing -Flower processing - Sago - Coffee - Cocoa - Coconut - Rubber - Spices processing – Beverage Industries -Landscaping wastes – characteristics – management - value addition

Unit V: Environmental ManagementSystems (EMS)

Eco friendly packaging - bio colorants - ­Eco labeling – occupational safety and health hazard management in horticulture industries–environmental legislations related to horticulture industries – Life Cycle Assessment - (LCA) - Environmental impact assessment - EMS - ISO 9000 - ISO 14000

Practicals

Wastewater treatment - physical, chemical and biological(Aerobic, Anaerobic) methods  - bioreactors - constructed wetlands - enumeration of anaerobic microbes -  solid wastes management–composting – vermicomposting - analysis of compost maturity indices – resource recovery – pectin - bioethanol production - value added products – visit to industries
