In an era where green development has become the dominant theme, Hangzhou Nanda Environmental Technology Co., Ltd.—a national high-tech enterprise driven by biotechnology innovation—is forging a path of ecological and economic synergy through its unique “Microbial+” scenario-based solutions.

Company Profile

Founded in July 2013, Nanda is committed to environmental technology and integrated environmental-agriculture research. Leveraging advanced biodegradation technologies, the company focuses on on-site harmless, reduced, and resource-efficient disposal of waste across diverse scenarios. It is a comprehensive enterprise integrating independent R&D, equipment manufacturing, and project operations.

Nanda’s core product—its Organic Waste biodegradation equipment—has been recognized as reachinginternational leading standards, maintaining the No.1 market share in China’s niche segment, and widely implemented across diversified domestic scenarios.

Upholding the mission of “Technological Carbon Reduction, Intelligent Future,” Nanda utilizes self-developed mesophilic aerobic microbes and intelligent digital disposal systems to degrade organic waste into liquid-phase products. These outputs are then used for carbon supplementation, fertilizer application, and microalgae-based carbon sequestration, forming a replicable and scalable green, low-carbon circular economic model.

Innovating with Technology, Creating the Future

INTELLIGENT TECHNOLOGY

Four Proprietary Technology Systems

Nanda has established a comprehensive technology R&D architecture:

1. Customized Microbial Agent Development Platform

By integrating traditional microbiology and microbial ecology with modern biochemistry and molecular biology—such as expression cloning, recombinant technologies, protein engineering, and high-throughput screening—the platform develops microbial products with strong stress resistance and high degradation efficiency.

2. In-house Patented Microbial Laboratory

The lab preserves over 200 strains of patented environmental microbes, including Lactobacillus, Bacillus, Saccharomycetes, Geotrichum, Trichoderma denitrifying bacteria, denitrifying cocci, nitrogen-fixing bacteria, photosynthetic bacteria, Acetobacter, and others, as well as microalgae such as Chlorella, Spirulina, and Phaeodactylum tricornutum—covering more than 90% of pollution scenarios.

3. Multi-Dimensional Bio-Enhancement Technology

By integrating compound microbial consortia, enzyme preparations, and nanocarrier technologies, Nanda achieves targeted pollutant recognition and rapid decomposition—effectively solving high-salinity, high-toxicity, and other complex environmental challenges.

4. Digital Biological Monitoring System

Through metabolic expression analysis, the system monitors microbial activity and environmental adaptation in real time, enabling precise regulation and delivering healthy, green, and high-efficiency ecological outcomes.

Main Business: Full-Chain Solutions

INTELLIGENT TECHNOLOGY

Nanda recognizes that no single model can address all scenarios. With a full portfolio of self-developed equipment and flexible cooperation models, the company delivers end-to-end solutions across all application domains.

01 Organic Solid Waste Treatment

Full-chain service: Sorting · Collection · Transport · Treatment · Recycling

Nanda provides flexible approaches to meet diverse site conditions:

• Distributed treatment model: Suitable for small to medium scales (<100 t/d), short transport distances, low cost, and reduced carbon emissions

• Centralized treatment model: Suitable for large-scale regional projects (>100 t/d), achieving economies of scale

  

Equipment capacity ranges from kilograms to hundreds of tons, covering cities, towns, campuses, restaurants, communities, cruise ships, enterprise parks, and even household kitchens.

02 Resource Utilization

Maximizing value recovery

The company achieves full resource utilization of organic waste, producing diversified products:

1. Oil extraction: Using biological cell-wall disruption technology to extract crude oil for biodiesel manufacturers

2. Carbon supplementation: Using high C/N ratio effluent as a premium carbon source for wastewater treatment plants

3. Organic liquid fertilizer: Blending effluent and solid residues into high-efficiency organic fertilizers

4. Microalgae-based carbon sequestration: Cultivating microalgae with effluent to simultaneously reduce emissions and recover resources

   

03 Ecological Restoration

For issues such as black-odor water bodies and heavy metal soil contamination, Nanda has developed specialized microbial agents targeting various pollutants. Through a bioremediation mechanism combining microbial binding and enzyme-assisted degradation—and supported by a full-process “Detection–Restoration–Maintenance” system—the company effectively transforms heavy metals, oil contaminants, and eutrophic substances.

Corporate Advantages: Dual Leadership in Technology & Business Model

INTELLIGENT TECHNOLOGY

01 Technological Advantages

1. Degradation rate ≥ 90%

For Organic Waste Disposal, Nanda’s kitchen waste degradation agents achieve >90% solid reduction within 24 hours under mesophilic aerobic conditions.

2. Treatment cycle reduced by 50%

In wastewater systems, Nanda’s composite microbial agents cut anaerobic/aerobic system start-up and recovery times by more than half.

3. Oil extraction rate ≥ 3%

Using biological cell-breaking technology, Nanda achieves >3% oil recovery from Food Waste—providing premium raw material for biodiesel production.

4. Sediment thickness reduction ≥ 40%

Nanda’s ecological dredging agents degrade organic pollutants in water and sediments, activating natural purification processes and reducing sediment thickness by over 40%.

02 Process Advantages

Compared with traditional high-temperature composting, Nanda’s mesophilic aerobic hydrolysis technology offers significant benefits:

• Gentle processing: Operates at 20–40°C, avoiding high-temperature energy consumption and odor leakage

• Lower capital investment: Equipment investment 400–500k RMB per ton, over 30% lower than traditional methods

• Higher operational efficiency: Electricity use only 8–15 kWh/ton—1/6 of traditional processes

• Superior resource recovery: Oil extraction improved by 30%, material reduction rate above 90%

• High automation: Fully automated control with minimal labor needs

  

03 Project Results

In 2025, Nanda and Hangzhou Environmental Group conducted a pilot project at the Tianziling Circular Economy Industrial Park using the mesophilic aerobic hydrolysis technology, achieving remarkable outcomes:

• Solid reduction rate: 83.24%

• Average oil content in hydrolysis liquid: 3.15%

• Research results accepted by the journal China Resources Comprehensive Utilization

  

Development Plan: Future-Focused Technology Layout

INTELLIGENT TECHNOLOGY

Nanda will continue to increase R&D investment, focusing on four strategic areas:

1. Synthetic Biology: Building efficient artificial bacterial consortia for targeted synthesis of enzymes, oils, and alcohols

2. Reverse Metabolism Research: Using gene or environmental modification to induce specific phenotypes

3. Symbiotic Microbial Research: Studying isolation and expression of symbiotic microorganisms

4. Co-metabolism Research: Developing co-metabolic degradation pathways for pesticides, fungicides, and other highly recalcitrant pollutants

   

Future Vision

Nanda aims to redefine the relationship between humanity and nature through biotechnology—improving ecological environments and enhancing quality of life.

The company is dedicated to contributing to national ecological civilization, the “dual-carbon” goals, and the building of a beautiful China.
