A Rapid Biocomposting Process for Dry Leaves and Garden Waste

Biomass wastes, particularly dry leaves are generated in voluminous amounts round the year. Their disposal through burning poses several hazards to human health and environment. Natural process of degradation is a time consuming phenomenon. The “Swachh Bharat Mission” campaign makes it mandatory that waste in any form should be processed at the source of generation. BARC has developed a method by which garden waste comprising of dry leaves is composted by the application of a formulation based on Trichoderma koningiopsis. The duration of compost formation can be considerably reduced by application of this formulation from years (through natural processes) to a few weeks. The process eliminates the cost of transportation involved in disposal of such waste. The compost generated in this process has high carbon content which will be beneficial in enriching organic matter depleted soils.

ADVANTAGES

  • Leaf compost can be used as good soil conditioner
  • Adds vital organic matter to soil and improves moisture retention
  • Ecofriendly alternative to leaf burning
  • Considerably reduces load of environmental pollution
  • Rapid biocomposting process
  • Promotes rural entrepreneurship

APPLICATIONS

  • Agricultural farms, nurseries, orchardsetc.
  • Municipalities, housing societies and institutional gardens
  • Biotechnology related companies and companies that mass produce microbial cultures.
  • Can be used for biocomposting of post harvest agriculture waste, weeds, sugarcane leaves etc.

INFRASTRUCTURE REQUIRED FOR PREPARING FORMULATION

A. Raw Materials

  • All the raw materials (sorghum grain, talcum powder) used for the development of this formulation are available locally. The strain of Trichoderma can be procured from BARC.

B. Equipments

  • Autoclave
  • Laminar flow
  • Refrigerator
  • Common glasswares

For rural areas alternative options for above equipments are Pressure cooker 8 litre or more capacity ,depending on amount of formulation to be prepared,Plastic trays, stacked- racks, common mixer grinder, antiseptic solution (Dettol or equivalent), surgical gloves etc.

C. Space

  • A small dust free room of 400 sq. ft. area (20 ft. x 20 ft).

D. Power

  • Both single & three phase power connection.

E. Manpower

  • One unskilled manpower for preparing formulation and 1-2 skilled workers would be adequate. Actual manpower would depend on production capacity.

INFRASTRUCTURE REQUIRED FOR BIOCOMPOSTING

A. Raw Materials

  • Formulation
  • Shredded dry leaves

B. Equipments

  • Shredder
  • Water sprinkler
  • Leaf rake (Panja)

C. Space

  • Net enclosure/concrete pit/drums (metallic or plastic)
D. Power
  • Both single & three phase power connection.

E. Manpower

  • 1-2 skilled/unskilled workers would be adequate. Actual manpower would depend on composting capacity.
