14. DEVELOPING INVESTMENT PLANS FOR VERMICOMPOSTING

Many variables need to be taken into consideration when determining the scale of investment

for vermicompost production. These;

➢ Whether it is for commercial or personal farm needs,

➢ Amount of accessible input organic waste,

➢ Financial resources owned,
➢ Environmental and climate conditions,

➢ Logistics and technical facilities,
➢ Traditional approach or technology usage preferences,

➢ Continuity of demand for Vermicomposting.

14.1. Small-Scale Investment

Small farms use pits and bins of various sizes (or IBC tanks) to meet their worm compost needs.

These systems, which do not require advanced mechanization, make sustainability possible for

small agricultural enterprises with low investment costs. In this section, the requirements for
annual 5 tons of vermicomposting production with IBC tanks are reported (Table 8).

14.2. Large Scale Investment

This section will provide an overview of the investment requirements and costs for a large-scale
vermicomposting plant (Table 9). People who are considering investing in this field can increase

or decrease the technical equipment needed depending on the production scale, mechanization
preference, amount of solid waste, and human resources. Windrow, raised bed and continuous

flow (flow through) systems are commonly used techniques in large-scale vermicompost

production.The presented facility will have a production capacity of 720 tons/year of solid
vermicomposting (Table 10). Creating a process with a continuous flow system in the facility

was simulated. The most important advantages of this system are that it enables the fertilizer to

be supplied continuously at the desired time and also saves time by performing the sifting
process. The return of investment is 2.1 years. The internal return rate of the investment is 41%.
