Environment research laboratory conducts research on environment related issues. Major programs of this laboratory are: Water and wastewater treatment; Hydrospheric and atmospheric research, Biodiversity conservation and climate change. In addition this laboratory also provides water quality monitoring and analytical service.
1. Water and Wastewater Treatment
- This program is focused on the development of cost effective methods for the removal of chemical contaminants (toxic metal, non-metal, and metalloids) from water and wastewaters using locally available low-cost materials.

2. Hydrospheric and Atmospheric Research
This program aims to study hydro-meteorological processes in the Himalayan region of Khumbu region. The specific objectives are to; study the impact of climate change on climatic extremes (rainfall and temperature), comparison of the satellite products, and possible applications for glacier monitoring.
3. Water Quality and Analysis Service
- Water Quality Analysis
The aim of this program is to provide water quality analysis service. Water samples of different sources like ground water, surface water, stone spouts, tap water and bottled water are analysed in this laboratory.
- Removal of organic arsenic using adsorbents from water
Organic arsenic such asmethylated arsenic in water has caused a series of health problems to human beings. Monomethylarsenate (MMA) and dimethylarsenate (DMA) are synthesized by some bacteria and fungi, which can be generated through the methylation of inorganic arsenic species such as arsenite and arsenate. Additionally, methylated arsenic species can enter into the environment via industrial and agricultural activities. As a result of the widespread distribution and toxicity of methylated arsenic in the environment, research on methylated arsenic removal from water is essential. The main objective of this investigation is to better understand the removal process of organic arsenic onto adsorbent.

4. Biodiversity Conservation and climate change
Mainly following programs are currently been conducted under Biodiversity Conservation research.
- Sustainable Harvesting Study and Promotion of In situ Cultivation of Medicinal and Aromatic Plants (MAPs) for Biodiversity Conservation.
Wide and wild collection of MAPsis one of the major problems of Churia forests of Nepal that has led to MAPs depletion causing forest disturbance consequently affecting biodiversity conservation. This program therefore aims to identify highly depleted MAPs and aware local people about sustainable harvesting techniques and practices to reduce biodiversity depletion. Moreover, this program also aims to promotein situ cultivation of highly depleted MAPs to reduce forest dependency of the local community and aid biodiversity conservation.
- Utilization of Seed PhenologicalModeling Tool for the Prediction of Plant Response to Climate Change.
This program aims to study seed physiology and phenologicaltraits and utilizephenological model a mechanistic modeling tool for the prediction of future plant regeneration and abundance in light of the projected climate change. This program aids in future forest management and climate change adaptation issues.
- Carbon measurements and carbon cycle research
Ecosystem-atmosphere carbon exchange in terrestrial ecosystem includes measurements of soil carbon dioxide emissions, micrometeorological data, and plant growth and production, ecosystem management, land use change, impact of warming and climate change on plant and ecosystem function.
