Training for Better Sorting
CEGEDI organizes targeted training sessions for

• Industrial company employees, teaching best practices for on-site waste sorting
• Collection staff, ensuring proper handling and segregation from the first contact
• Environmental and safety managers, integrating waste management into company procedures

Beyond the professional context, CEGEDI also conducts community awareness campaigns in areas with high industrial activity or near treatment sites. These initiatives aim to:

• Promote eco-friendly practices (selective sorting, waste reduction, good habits)
• Inform communities about the risks of poorly managed waste
• Encourage active citizen participation in environmental protection

These activities take the form of meetings, workshops, radio programs, visual materials, and school campaigns.

A Lasting Impact on Environment and Society
Through these training and awareness efforts:

• Waste is better sorted at the source, facilitating recovery and recycling
• Companies become active contributors to environmental preservation
• Communities develop a sustainable ecological culture

CEGEDI thus promotes a culture of behavioral change and collective responsibility regarding environmental challenges.

On-Site Treatment Adapted to Waste Types
CEGEDI has internal capabilities to process certain types of waste on-site, including

• Pre-treatment of used oils (settling, filtration)
• Shredding or compacting of solid waste
• Secure packaging of hazardous waste

These operations help reduce volume, neutralize hazards, or prepare waste for further recovery.

Partnerships with Specialized and Certified Facilities
For waste that cannot be treated locally, CEGEDI collaborates with ISO-certified international partners specializing in:

• High-temperature incineration
• Recycling of electronic, plastic, and metal waste
• Treatment of chemical and medical waste

All exports comply with international regulations on transboundary waste movements (Basel Convention, etc.) and are fully traceable.

Waste Recovery: An Ecological and Economic Lever
Rather than systematic disposal, CEGEDI focuses on recovering valuable materials, such as:

• Recyclable: paper, plastic, scrap metal, glass
• Reusable: regenerated oils, refurbished equipment
• Transformable: organic waste for composting

This approach reduces the exploitation of natural resources, lowers landfill costs, and promotes the local green economy.

Safety, Compliance, and Performance
All treatment steps follow strict procedures to ensure operational safety, environmental protection, and compliance with national and international standards. Regular checks guarantee the quality and effectiveness of the treatment process.

Modern and Specialized Infrastructure
CEGEDI operates two major sites for sorting and storage

• A 3-hectare private landfill in Maferinyah (Forécariah Prefecture) for receiving, sorting, and storing various types of solid waste.
• A 4-hectare site dedicated to used oil management in Tanènè (Dubréka Prefecture), equipped for handling and storing liquid waste, particularly hydrocarbons.

These facilities are secure, monitored, and built to regulatory standards to prevent pollution or accidents.

Rigorous Selective Sorting
Upon arrival, waste is classified according to its nature:

• Recyclable waste (plastic, metal, paper, cardboard)
• Hazardous waste (chemicals, solvents, batteries)
• Organic waste
• Non-recyclable waste

This sorting maximizes recovery, reduces landfill disposal, and directs waste to the appropriate treatment channels (processing, export, composting, etc.).

Safe and Compliant Storage
Waste is temporarily stored in designated and isolated areas. Each type of waste is placed in suitable containers, bins, or tanks to ensure:

• Leak-proof containment
• Prevention of emissions and spills
• Safety for staff and surrounding communities

Sites are regularly inspected to check material stability, and emergency procedures are in place in case of incidents.

A Strategic Step for the Circular Economy
By implementing efficient sorting and structured storage, CEGEDI actively contributes to reducing landfill use, conserving natural resources, and promoting the reuse or transformation of waste.

National Coverage
CEGEDI operates throughout Guinea, with the capacity to intervene in urban, industrial, and rural areas. Equipped with a fleet of specialized vehicles (dump trucks, hook-lift trucks, tankers for liquid waste, etc.), the center can meet the specific needs of companies, institutions, and local communities.

All Types of Waste Managed
The service covers a wide range of waste, including:

• Solid industrial waste (metals, plastics, cardboard, wood, etc.)
• Liquid waste (used oils, solvents, polluted water)
• Hazardous or high-risk waste (batteries, chemicals, medical waste)
• Organic waste intended for composting

Each type of waste is properly packaged and safely transported to sorting, treatment, or recovery facilities.

Traceability and Regulatory Compliance
CEGEDI ensures complete traceability of collected waste from pickup to final disposal. Tracking forms are issued for every operation, ensuring compliance with national and international regulations.

Commitment to the Environment
Collection and transportation are organized to minimize ecological impact, optimize routes, reduce greenhouse gas emissions, and comply with strict safety standards. Personnel involved in these operations are trained and equipped to follow best environmental practices.

Organic waste from agro-food industries, markets, restaurants, and green spaces represents a significant portion of overall waste. When poorly managed, it can cause nuisances such as odors, insect proliferation, and leachate production.

CEGEDI implements a controlled composting process that allows us to:

• Stabilize organic matter
• Eliminate pathogens
• Produce a safe and fertile final product

Composting at CEGEDI

Composting is carried out in dedicated areas on CEGEDI sites. The process follows several steps:

1. Sorting and preparing organic waste (excluding plastics and non-biodegradable materials)
2. Shredding and mixing with structural materials (dry leaves, wood chips)
3. Aerobic fermentation in windrows or bins, with regular turning
4. Maturation to stabilize the compost and improve its quality
5. Sieving and packaging of the finished product

Throughout the process, temperature, humidity, and aeration are monitored to ensure high-quality compost that meets agricultural standards.

A Natural Fertilizer for Agriculture

The compost produced by CEGEDI is a nutrient-rich organic amendment (nitrogen, phosphorus, potassium), ideal for:

• Enriching agricultural soils
• Reducing the use of chemical fertilizers
• Improving soil water retention
• Stimulating crop growth

This compost can be made available to agricultural cooperatives, local communities, and environmental projects, contributing to the promotion of sustainable agriculture in Guinea.

A Positive Environmental Impact

Composting not only reduces the amount of waste sent to landfills but also helps limit greenhouse gas emissions, particularly methane. It provides a clean, local, and economical alternative to the disposal of organic waste.
