    An Actor-Interest-Power (AIP) governance indicator framework for operationalising the Actor-Centred Power approach
    (Elsevier, 2026-08-03) Daniel Karthe
    Systematic analysis of complex social relations in environmental governance requires clear identification of actors, their interests, power distribution, and interactions. While the Actor-Centred Power (ACP) approach provides a theoretical foundation for analysing governance processes, its application has remained predominantly qualitative, limiting transparency, comparability, and reproducibility across governance contexts. This study develops a structured Actor-Interest-Power (AIP) analytical framework that operationalises the ACP approach by integrating actor interests and power distribution within a transparent and comparable analytical procedure. The framework combines structured actor-interest scoring, power assessment, and Principal Component Analysis (PCA) to enable systematic exploration and comparison of governance configurations. Drawing on empirical data from mangrove forest management in Thailand, a subset of actors and interests is reanalysed to demonstrate the application of the framework. To further illustrate its analytical utility, six conceptually constructed AIP typologies representing contrasting governance configurations are developed, ranging from aligned high-power structures to fragmented and asymmetric arrangements. Together, the empirical application and conceptual typologies demonstrate how different Actor-Interest-Power (AIP) configurations can be systematically represented and compared within a consistent analytical framework. By operationalising Actor-Interest-Power relationships into a structured analytical framework, this study advances the practical application of the ACP approach and contributes to the development of transparent, reproducible, and configuration-based governance indicators for comparative sustainability assessment and planning.

    Determination of Deoxygenation Rate Constant for BOD Reaction in Mongolia
    (GMIT, 2019) Sanchirgarav Batzorig; Ariuntuya Tserendor; Daniel Karthe
    The objective of this study was to estimate the deoxygenation rate constant and the ultimate BOD of WWTP effluent in Mongolia. The deoxygenation rate was determined and tested in April, 2019. The Deoxygenation rate was 0.31 /day which is a bit higher than values from other countries. The ultimate BOD was in the range of 92- 115 mg /L. Biological oxygen demand values did not meet the limits recommended by the Mongolian National standard throughout entire study period.

    Managing automotive end-of-life NiMH and Li-ion batteries in Mongolia: a Material Flow Analysis to assess challenges and opportunities for circular batteries in the Global South
    (Frontiers Media S.A., 2026-02-12) Gantuya Ganbat; Daniel Karthe
    Introduction: Mongolia’s transition to electric mobility presents environmental opportunities to mitigate air pollution and potentially reduce greenhouse gas emissions but also generates complex waste streams such as end-of-life (EoL) Nickel Metal Hydride (NiMH) and Lithium-Ion Batteries (LIB). This study investigates the status of Mongolia’s waste management system and how it can be optimized to enhance the circularity of such waste streams. Methods: Original data was collected through field research at collection, repair, storage, and disposal sites, and complemented by stakeholder interviews and an analysis of the country’s waste management legislation. Official vehicle fleet statistics (2010–2023) were used to forecast the quantity of EoL NiMH and LIB until 2050 and conduct a Material Flow Analysis for 10 different scenarios. The dataset comprises both qualitative data, describing the current waste management scenario, and quantitative data on vehicle imports, fleet composition, and battery specifications, with assumptions for missing values based on market trends. Results: Results reveal that Mongolia lacks infrastructure and policy for safe and sustainable EoL battery management. EoL battery outflows were estimated using a two-parameter Weibull distribution model; forecast reliability was assessed via out-of-sample backcasting of the vehicle-fleet projection against historical fleet statistics (2019–2023 hold-out: MAPE = 4.71%). The results of the EoL battery quantities are scenario- and parameter-dependent projections for the lifetime and battery-specification assumptions. The results show that cumulatively (from 2023 to 2050), in the Current Scenario, 10,302 tons of EoL NiMH and 38,650 tons of EoL LIB are expected to be generated. In contrast, for the Climate Focus Scenario, 10,455 tons of EoL NiMH and 102,586 tons of EoL LIB are expected. Discussion: The lower values of NiMH in 2050 are due to the expected transition from NiMH to LIB in HEV. Recommendations to enhance EoL battery management’s circularity include focusing on improving EoL battery collection, implementing Extended Producer Responsibility, integrating the existing informal sector, enhancing regional and international cooperation, and improving data acquisition and management. In summary, a combined approach involving local and international cooperation and socio- and technological development is essential for improving the circularity of EoL battery management in Mongolia. 1 Introduction

    Plastic in the environment of Nalaikh
    (GMIT, 2020) Bat-Erdene Purevsuren; Daniel Karthe; Enkhjargal
    Plastic is one of the most produced material in the world due to its flexibility and cheap cost to produce and plastic production has been growing since 1950 and expected to keep on growing. Once plastic product is used and becomes waste plastic becomes problem to the environment. First of all, shear amount of the plastic and plastic accumulation due to slow degradation of plastic and additionally plastic waste causes problems such as entanglement, ingestion, leaching. On top of negative environmental impacts plastic waste is a health hazard as well.

    Study of wastewater treatment based on the DAF for the small-scaled industry
    (GMIT, 2020) Nandin-Erdene Munkhbat; Ariuntuya; Daniel Karthe
    Most of the Mongolia industry scale is small sized industry comparing other country. Therefore, there is an important need of small scale pre-treatment plant of industrial wastewater in Mongolia. As nowadays requirement for protecting environment, all small scale industry have to install WWTP before discharge the wastewater into environment and sewerage network. The wastewater treatment plant at a poultry slaughterhouse comprises a dissolved air flotation (DAF) system. The DAF system at small-scale industries especially poultry wastewater treatment is designed to remove high concentration of organic pollution such as FOG, BOD, COD and TSS. Formulated on the literature, the DAF operation of the system removal efficiency at 300kPa pressure, PAC coagulation and anionic polymer is shown optimal result
