SectorMost major industry classification systems use sources of revenue as their basis for classifying companies into specific sectors, subsectors and industries. In order to group like companies based on their sustainability-related risks and opportunities, SASB created the Sustainable Industry Classification System® (SICS®) and the classification of sectors, subsectors and industries in the SDG Investor Platform is based on SICS.

Business Model Description

Invest in/provide project financing to install biogas digesters for biodegradable waste management by Local Authorities (LAs), commercial establishments and households with end-use energy applications (thermal and electricity). There are 4 digester capacity levels in waste input: (i) Municipal councils: 10 tonnes/day; (ii) Urban councils and Pradeshiya sabha: 1 tonne/day; (iii) Institutions/Commercial: 500 kg/day; (iv) Households: 5 kg/day.

Biogas digesters: Presently, numerous private companies are involved with the design and installation of biogas systems, mainly for thermal energy applications. Design and development of biogas systems are also performed by R&D institutes, including universities. The lead government agency is the National Engineering Research and Development Centre (NERDC). Examples of companies active in the IOA:

Arpico Plastishells Limited: Since 2011, the company markets innovative biogas plants (Arpico Green Gas /Unit) in three capacities (0.5 m3, 1.0 m3 and 5.0 m3), which are all manufactured through a signed agreement with an inventor. These are promoted and sold to HHs, hotels, restaurants, manufacturing plants, large-scale businesses and SMEs, which can produce Biogas through organic waste (17).

Eco Tech Base (ETB): ETB is a private entity, working in RE, waste management and the agriculture sector since 2013. The biogas plant is one of their main products, with a wide range of capacities (3 kg/day to 2 t/day). A new invention named "Eco-Buddy" has been a popular design among institutions and households. So far, they have installed Biogas plants in 30 institutions, 5 LAs and 400 HHs (15).

Janathakshan (GTE) Limited: A not-for-profit company established in 2011 to promote sustainable and green solutions in the development of Sri Lanka and beyond. It specializes in promoting viable and decentralized RE options and has vast experience developing domestic/large-scale biogas systems. One of the highlights is the 20 t/day capacity biogas plant in a Municipal Council (16).

HELP-O: It works in 4 focus areas, Environment Conservation, Public-Private-Partnership for Social Responsible, Community Development, and Relief Assistance. One of the key programmes implemented is the deployment of biogas digesters. The first system was installed in 2004 (at a hospital), and since then, several such systems were installed covering institutions, domestic and communities (14).

Expected Impact

Deployment of biogas plants in LAs, institutions, commercial sector and HHs, while providing benefit of waste management, clean energy and organic fertilizer for agriculture.
