In addition to reducing environmental risks through waste reduction, extending the useful life of resources, and returning materials to the production cycle, this process has significant potential for developing the green industry and reducing dependence on imported raw materials.
Our Products
1. Smart Management of Municipal and Industrial Waste
The study and development of innovative products and technologies for converting waste into energy (electricity and heat), with the aim of reducing waste volumes, supporting decarbonization, and creating clean energy resources.
These studies include the following:
1-1. Waste-to-Energy Processes
Waste-to-energy plants are regarded as one of the key solutions for sustainable municipal waste management and renewable energy generation, and are expected to play an important role in the future of the power and environmental industries. By directly converting municipal and agricultural waste into thermal energy and subsequently electricity, these plants simultaneously address two major challenges: waste accumulation and dependence on fossil fuels. They also help reduce greenhouse gas emissions and prevent improper waste disposal.For MAPNA MD1 and MAPNA Group, entering this field represents not only a technological and economic opportunity to diversify the portfolio of products and services, but also a response to the country’s urgent need for waste management and the implementation of national policies aimed at reducing pollutants and developing clean energy. Developing capabilities in the design, construction, and operation of waste-to-energy plants can strengthen MAPNA’s position as a leading player in the regional energy and environmental markets while creating new opportunities for investment, technology exports, and value creation in the energy and urban services sectors.
1-2. Anaerobic Digestion
Dry anaerobic digestion is a biological process in which organic matter contained in municipal solid waste is decomposed by anaerobic microorganisms under conditions of oxygen absence or deficiency. During this process, organic matter is converted into biogas, primarily methane and carbon dioxide, and a stabilized material known as digestate.
The main stages of this process include hydrolysis, acidogenesis, acetogenesis, and methanogenesis, each of which plays an important role in breaking down and converting organic compounds. Anaerobic digestion is typically carried out in an enclosed tank known as a reactor. Depending on the type of feedstock, such as food waste, animal manure, or sewage sludge, as well as site conditions, reactors are designed in various configurations and sizes.
The biogas produced through this process, which contains a significant proportion of methane, can be used as a fuel for energy generation. In this approach, the collected biogas, after treatment if required, is supplied to a generator engine or a combined heat and power (CHP) system. In addition to electricity generation, the heat produced can also be used to heat the reactor.
Entering the field of designing, constructing, and operating anaerobic digestion systems and waste-to-energy plants can strengthen MAPNA MD1’s position in the growing clean energy market and urban infrastructure projects, while creating opportunities to participate in domestic and regional waste-to-energy projects.
1-3. Landfill Gas-to-Energy (LFGTE)
Landfill Gas-to-Energy (LFGTE) is based on converting methane generated from the decomposition of waste into electricity and heat and represents a natural extension of MAPNA MD1’s experience in small-scale power plants and CHP systems. The main difference between such projects and conventional CHP systems lies in the use of a low-quality, variable, and corrosive fuel, as well as the need for specialized infrastructure for landfill gas extraction, treatment, and management.
To date, no industrial-scale and locally developed LFG power plant has been implemented in Iran, and existing projects have mainly relied on flaring or limited use of natural-gas generators. Successful implementation of such a project requires the design of corrosion-resistant generators, advanced filtration and drying systems, and professional landfill engineering and management.
In addition to reducing methane emissions and environmental pollution, this project can enable MAPNA MD1 to enter the emerging market of renewable energy generation from municipal waste.
2. Design of Advanced Water and Wastewater Treatment Systems
The study and design of technological solutions for improving water quality, increasing water resource efficiency, and reducing pollution caused by municipal and industrial wastewater.
These studies include the following:
2-1. Biological Activated Carbon (BAC) Filter
Biological Activated Carbon (BAC) is a combined physical-biological treatment process for industrial and municipal wastewater in which granular activated carbon (GAC) is used to simultaneously adsorb pollutants and provide a suitable environment for microorganisms to grow and biologically degrade contaminants.
Therefore, in addition to pollutant adsorption, which is a physical treatment mechanism, biological degradation of organic matter also takes place on the carbon granules. As a result, the removal efficiency of organic matter in biological activated carbon filters is significantly higher than that of conventional activated carbon filters.
Today, BAC filtration is recognized worldwide as one of the most effective and sustainable tertiary treatment technologies. Its widespread use in Europe and its gradual adoption in Asia and North America demonstrate the high potential of this technology for removing emerging contaminants and micropollutants and preparing treated wastewater for reuse.
In line with efforts to increase wastewater treatment efficiency and maximize the recovery of reusable water from wastewater, BAC has been considered as a research project at MAPNA MD1.
2-2. Improving Industrial Water Treatment Plant Efficiency Using Closed-Circuit Reverse Osmosis (CCRO)
This system is an innovative approach to improving the operating efficiency of reverse osmosis (RO) systems. As one of the latest approaches in this field, its application can increase recovery, reduce wastewater generation, and decrease raw water consumption.
The CCRO system is based on the same fundamental principles as conventional reverse osmosis systems and consists of high-pressure pumps, membranes, and pressure vessels. However, modifications have been made to the wastewater system and membrane configuration, while the operating method differs significantly from conventional systems.
In brief, CCRO combines the advantages of dead-end filtration with the power of cross-flow filtration. Unlike conventional RO systems, which are generally configured as multi-stage systems, CCRO consists of standard components in a single-stage configuration, together with a new generation of membranes.
Advantages:
- High recovery of up to approximately 98%
- Suitable for feed water with variable quality
- Suitable for feed water with high silica-ion concentrations
- Reduction of RO brine and, consequently, reduction of the final wastewater discharged to evaporation ponds
- Reduction in the required evaporation pond area
- Reduced withdrawal of raw water from natural sources, including wells, rivers, and reservoirs
- Reduced size of the site’s inlet pipeline
- Reduction of RO stages from two to one, along with a reduction in the associated valves and piping
- Extended membrane service life
- Reduced frequency of periodic chemical cleaning (CIP)
- Reduced consumption of anti-scalant chemicals
2-3. Focus on Zero Liquid Discharge (ZLD) Technologies
Given the water crisis and limited water resources in many regions of the country, the reuse of saline wastewater and recycling of industrial wastewater have emerged as sustainable solutions for securing water supplies in industries and reducing environmental pollution.
The Zero Liquid Discharge (ZLD) approach, which aims to completely eliminate the discharge of liquid wastewater into the environment and recover more than 95% of the water contained in wastewater, is particularly important for water-intensive industries such as power plants, petrochemical facilities, and steel plants.
At MAPNA MD1, various approaches to maximizing water recovery from saline wastewater are being studied as research projects.
