Proceedings of ChemECon 2023 Solutions worth spreading
Dye sensitized solar cells using natural dyes derived from chaetomorpha, microcladia borealis, elisolandia elongate and sea lettuce

Illlankoon, HMUB; Sumudushantha, WANT; De Alwis, A; Perera, U [Conference-Abstract]

Natural dye-sensitized solar cells (DSSCs) are a promising area in renewable energy. These innovative devices employ natural dyes extracted from plants to absorb sunlight and convert it into electricity. The dyes ...
Effect of biofilm growth in anaerobic reactor treating dairy wastewater

Eranda, JADV; Kalpani, WHA; Darshana, WAC; Rathnasiri, PG [Conference-Extended-Abstract]

In this study, attention was given to anaerobic digestion of dairy wastewater, which has higher COD levels and a nutritional rich media for microbial growth. Generally, Fixed Bed Biofilm Reactors are significant in treating ...
Effect of co-digestion on the lipid inhibition in anaerobic digestion of desiccated coconut wastewater

Anjana, WTC; Jayathunga, P; Rathnasiri, PG [Conference-Extended-Abstract]

Seven anaerobic batch reactors were run varying the Desiccated Coconut wastewater (DC) to Food Waste (FW) ratio at room temperature and the daily gas production and CH4 content was determined. Mono digestion of DC ...
Effect of micro aeration on anaerobic treatment of sulphate and ammonia rich wastewater

Priyadarshika, SKMRP; Wittahachchi, RM; Costa, KPCL; Rathnasiri, PG [Conference-Extended-Abstract]

Microaeration is a stratergy applied during anaerobic conversion to improve treatment efficicency. The objective of this study is to investigate the effect of microaeration on a combined effect of sulphate and ammonia ...
Effect of particle size on optimum air levels required for packed bed combustion of biomass

Arunasiri, RADS; Samaranayake, AWN; Samarawickrama, SLTM; Silva, SAB; Narayana, M [Conference-Extended-Abstract]

A relation between the particle size and excess air flow rate for packed bed combustion of biomass has been the objective of this research project. Particles of square cubes of different dimensions and different air flow ...
Effect of saltwater on cementitious capillary crystalline waterproofing

Gallage, KGCS; Jayanath, JHC; Kasun, NHT; Mallawarachchi, D; Amarasinghe, ADUS [Conference-Extended-Abstract]

Effect of urea-based activators on reinforcing activity of silica in natural rubber-based compounds

Ambewela, D; Bhashini, JWM; Elvitigala, PSH; Gunapala, O [Conference-Extended-Abstract]

Silica-filled rubber compounds has a high demand for making white and colored rubber products. Silica-filler has high reinforcing ability compared to other white-fillers. Traditionally, polyethylene glycol (PEG) is used ...
Efficient production of dimethylfuran (DMF) from hydroxylmethylfurfural (HMF) using catalytic hydrogenation reaction

Kekulawala, KVLW; Udayakumara, HPCS; Subasinghe, T. [Conference-Extended-Abstract]

In a time of steady decline in oil reserves, instability in oil prices, strong environmental legislation and global warming concerns, researchers and oil companies are actively seeking cost - effective processes to convert ...
Employing indigenous microalgae for third generation biofuel production

Maduwanthi, MKC; Nuwanthika, WHC; Withanage, PK; Ariyadasa, TU [Conference-Extended-Abstract]
