Resource Recovery from Septage

 

Introduction

 

The effluent from septic tanks still contains most of the sewage nutrients. Hence, the present proposal aims at recovering sanitised soil and fertilisers from septic tanks while adequately abating pathogens and organics. The main purpose of this proposal is to develop financially affordable and simple-to-operate decentralised technologies that will produce effluent for safe disposal and products for agricultural re-use.

 

State of Development

 

Pre-commercialization

 

Unique Features of the Product/Technology

 

TerraPreta undergoes two types of composting-first lactofermentation followed by vermicomposting. The presence of charcoal in Terra Preta is highly advantageous as it is very stable and remains in the soil for thousands of years, binding and retaining minerals and nutrients. The product is quite affordable similar to other composts. This product not only meets the requirement for high organic matter fertilizer but also helps in treating septage.

 

Market Potential

 

Given the high organic content in Indian urban municipal waste, less upfront capital expenditure, as well as ease of adoption in decentralized setting, composting is also expected to grow from about 26,000 TPD in 2017 to 66,500 TPD in 2052. Compitition could be compost from other sources.
