Vol. 1 No. 2 (2021) Green chemistry for environmental problem solutions
There is a need for managing the environment and green chemistry becomes the promising approach to achieve this aim. Green chemistry refers to the design and synthesis of environmentally benign chemical processes, which include the development of biomaterials and synthesis of bioproducts from natural resources. This concept focuses on the reduction of the use and fabrication of hazardous chemicals.

Abstract
Anthracnose disease in chillies is a serious problem for farmers. So far, synthetic fungicides have been used as solution for the treatment of this disease. However, the side effects of synthetic fungicides to public health and environment raised awareness on alternative fungicides derived from natural resources. This paper aims to review plants that are potential as an alternative to f

Abstract
There are several environmental issues caused by economic growth and urbanization, such as soil degradation, water scarcity, deforestation, and biodiversity extinction. To solve these environmental problem issues, cleaner production (CP) had presented as account to reduce waste generation, energy usage and environmental pollution.CP concept was accepted and applied on many industrial sectors.

Abstract
This paper presents on removal of silver nanoparticles using phytoremediation. In this study, floating macrophyte (Pistia stratiotes) was used for phytoremediation of silver nanoparticles. This study investigated the performance of Pistia stratiotes in the removal of silver nanoparticles using phytoremediation method. The silver nanoparticles were green synthesized by using Muntingia calabura s

Abstract
A preliminary morphological screening and isolation of bacterial colony from latex industrial wastewater was carried out. Bacteria colonies from latex processing wastewater were isolated from a local latex processing industry. It was found that 17 bacterial isolates had been purified grown on nutrient agar under 35˚C. The colonies were then purified and morphologically indicated via Gram stain

Abstract
The SARS CoV2 pandemic has a tremendous impact on both developed and developing countries. To mitigate against community transmission of SARS CoV2 in Southern Bhutan and Central Bangladesh, the development and application of appropriate technologies was undertaken. As an appropriate mitigation, hand washing station was constructed by a simple system. The system was operated using a foot peda
