High conversion of wastewater into biomass of photosynthetic bacteria was investigated. This biomass is possibly utilized as feed for fish or extraction source of PHA (polyhydroxyalkanoate). As a fundamental investigation, batch experiments were carried out using purple nonsulfur bacteria Rhodobacter sphaeroides to determine the growth rate and yield and to quantify CO2 release/uptake during substrate assimilation. The substrates used for this study were five kinds of VFA namely, acetate, propionate, n-butyrate, n-valeric acid and n-caproate. Growth rates for n-valeric acid and n-cvaproate were lower than those for other VFAs. Yields, defined as carbon in bacteria divided by removed organic carbon, for n-butyrate, n-valeric acid and n-caproate exceeded 1 due to simultaneous CO2 uptake and no net greenhouse gas emission. Maximum CO2 uptake was 17% of removed DOC (dissolved total organic carbon) in the case of n-valeric acid supplemented with 2.00 g/l of NaHCO3.

Building construction sector can play a major role in reducing Greenhouse Gas emission through application of technologies aimed at reduction of use of building materials. Energy consumed during production of building materials and components plays a crucial role in creating environmental pollution. India is witnessing high growth in urban and rural housing, which needs more production of building materials. Permanent or semi-permanent type buildings which consume easily available conventional materials like brick, reinforced cement concrete etc. can be made Economic and Eco-friendly by lowering use of energy-consuming building materials through Cost-effective Construction Technologies. Buildings with Cost-effective Construction Technology can be designed within the parameters of the existing Indian Standards. Awareness generation among the users, proper technical and architectural guidance and easy availability of skilled manpower are of utmost importance for promotion of cost-effective technologies in India and to make them as the most acceptable case of sustainable building technologies both in terms of cost and environment.
