Hope on Climate Change: Reasons to be optimistic

Article
| July 5, 2021

The total commitments made under the Paris Agreement were too little to limit global warming to 2 degrees Celsius, whereas scientists agree that limiting warming to 1.5 degrees Celsius is vital. Ajay Shankar says that recent developments give cause for optimism for the first time as the President of the USA has brought the USA back into the Paris Agreement and is providing leadership for a net carbon-neutral global economy.

Tourism in the new normal post Covid-19: Is eco-tourism the solution?

Article
| July 5, 2021

The acknowledgement by policymakers, host communities, and even some travellers on the negative effects of mass tourism have led to formulation of policies on sustainable tourism Sustainable tourism builds on the basic principles of local procurement while assimilating local culture.

Nanoscale 2D semi-conductors – Impact of structural properties on light propagation depth and photocatalytic performance

Research Paper
| June 29, 2021

The performance of photocatalytic materials are largely dictated by the crystalline and optical properties of the semi-conductors. The density of photo-generated electron and hole pairs is greatly influenced by the light penetration in photocatalytic material, leading to specific degradation kinetics. In this work, the relationship between the metal oxide film thickness and the overall materials optical and photocatalytic performances are systematically established for the first time.

Novel pilot scale photocatalytic treatment of textile & dyeing industry wastewater to achieve process water quality and enabling zero liquid discharge

Research Paper
| June 22, 2021

This paper presents a novel end-to-end pilot scale photocatalytic treatment of real textile & dyeing industry effluent, which involved innovative approach in primary treatment, followed by Heterogenous Photocatalysis (HP) involving nano-TiO2/UV as secondary treatment and suitable filtration leading to treated water meeting process water quality enhancing water re-use efficiency. This enables Zero Liquid Discharge (ZLD); which is the need of the hour in tackling problems of po.int source pollution and Water Conservation in developing countries like India.

Surfactant-modified titania for cadmium removal and textile effluent treatment together being environmentally safe for seed germination and growth of Vigna radiata

Research Paper
| June 21, 2021

The present work describes synthesis, detailed characterization, and application of bare and surfactant-modified titania nanomaterials (NMs) for various wastewater treatment applications as individual cases like cadmium (Cd) removal, methylene blue (MB) dye degradation, and treatment of real textile and dyeing industry effluent. These NMs are used as adsorbents and photocatalysts in an indegenously developed end-to-end treatment process and a photocatalytic reactor for treatment of textile wastewater.

Improving energy efficiency and economic feasibility of photocatalytic treatment of synthetic and real textile wastewater using bagasse fly ash modified TiO2

Research Paper
| June 21, 2021

TERI (The Energy and Resources Institute) has recently developed a novel wastewater treatment technology called TERI Advanced Oxidation Technology (TADOX), which provides an end-to-end treatment of textile and dyeing industry wastewater within a few hours without any kind of bioremediation in the treatment trail. It involves UV/n-TiO2 Photocatalysis during secondary treatment; Photocatalysis, is a promising approach for treating difficult wastewater, however there is always effort to reduce cost and electrical energy consumption.
