  • From Refuse to Resource

Mainstreaming concepts and practices of environmental sustainability within its initiatives is central to the goals of Dilmah Conservation. In line with these objectives, the Dilmah Conservation Sustainable Agriculture Research Centre (DCSARC) seeks to optimise the use of natural resources and mitigate impacts on the environment. Towards this effect, a kitchen and organic waste treatment plant was recently completed at the DCSARC premises in order to productively recycle organic waste generated at the premises and transform refuse into a resource. The facility was declared open by Dilmah Founder Merrill J. Fernando on 2nd December, 2014.

The natural decomposition of organic materials can be harnessed as an environmentally-sound means of generating renewable energy. When organic materials are broken down in the absence of oxygen, biogases are produced. Mainly comprising Methane (CH4) and Carbon Dioxide (CO2), biogas can be produced by processing green waste including kitchen and garden refuse in anaerobic conditions, which in turn can be converted to usable energy.

The biogas plant at DCSARC will contribute towards fulfilling energy requirements for cooking purposes, while waste generated will be used as a bio fertiliser in cultivation.

At a daily waste feeding capacity of 500 Kg, it is anticipated that this plant will generate 5.5 cubic meters of biogas every day.

This biogas plant will ensure greater environmental and financial sustainability by helping streamline waste disposal and reduce associated costs, pollution and dependence on non-renewable energy resources, while supplementing organic gardening initiatives at DCSARC.

The production of clean energy from recycled waste by way of building a biogas plant features as a part of Dilmah Conservation’s efforts to use renewable energy sources within its initiatives.
