Rapid Conversion of Domestic Organic Waste and Sewerage into Organic Fertiliser to Minimise the Hassle and the Cost of Organic Waste Handling and Sewerage Treatment in Condominiums, Tall and Green Buildings

Abstract

Household Organic solid waste (HOSW) disposal is a hassle to the house holder and a high cost operation for the local authorities, where it has to be manually collected, transported in garbage trucks and disposed at solid waste dumps located a long distance away. At present, most dump sites have become Garbage Mountains, filled to the brim and at the verge of collapsing and submerging human habitats located in their vicinity, like the “Meethotamulla Municipal Solid Waste Dump Disaster”. In condominiums and tall buildings, where a large number of people live in a small area, the problem is more sever, since a large number of houses are located and HOSW has to be carried manually in lifts or by climbing down large numbers of steps to the round level and dumped into garbage containers, which is collected once in 2–3 days by garbage collectors and disposed at dump sites. In Condominiums, design, construction and operation of sewerage treatment systems, mainly consisting of aerobic and anaerobic microbial digestion has a very high capital cost and a high operational cost. After treatment, the waste water should meet CEA approved parameter values for disposal to the city sewerage system. The paper discusses and provides results of a research project carried out by the author, where HOSW and sewerage were converted into low cost, germ free, odourless, organic fertiliser containing high C, H, O, N, P, K, Ca, Mg by using Delta-D Technology, as a solution to the problems described above. Delta-D Technology is a patented technology developed by the author to rapidly convert all types of organic waste into organic fertiliser.
