Most countries in West Africa (Nigeria, Ghana, Ivory Coast, etc.) have issued Environmental Law and Regulations on Solid Waste Management. The environmental departments of all countries are responsible for the overall supervision of domestic waste, and it is strictly prohibited to dump and burn waste in the open air. It is mandatory to establish a basic waste recovery and treatment system in cities. Enterprises violating the rules will face high fines. Some countries are gradually promoting the Extended Producer Responsibility (EPR) policy to promote waste closed-loop management. As an area with dense population and fast urbanization in Africa, the domestic garbage treatment in West Africa is facing serious difficulties: Lagos, Nigeria, Accra, Ghana and Abidjan, Cote d'lvoire produce about 12000 tons of domestic garbage per day, 6000 tons per day and 7000 tons per day respectively. The organic wastes in these wastes account for 55% - 60% of the total, including a large number of fruit and vegetable residues, catering wastes and agricultural by-products. Most of the wastes are stacked at the edge of the city, forming large garbage mountains, which not only emit odor and breed mosquitoes, but also produce leachate to pollute the surrounding rivers and waters, and exacerbate public health hazards. West Africa has a tropical climate, with high temperature and much rain all the year round and high humidity. In rainy season, the rainfall is concentrated and heavy rain is frequent, and the garbage is easy to deteriorate and decay quickly, which intensifies the diffusion of pollution; There is a significant gap between urban and rural development, and there is a lack of urban infrastructure waste treatment facilities. In rural areas, the method of random discarding and open-air stacking is mostly adopted. Meanwhile, local farmers are highly dependent on imported chemical fertilizers, and the planting cost is high. Therefore, a weather-resistant and moisture-proof, low-cost, easy to operate and maintain domestic waste treatment equipment complying with the concept of circular economy is urgently needed to solve the problem of waste accumulation and enable the development of local circular agriculture.

Targeted research and development of "West Africa Weatherproof Recycling" domestic garbage treatment equipment of China Yongle Environmental Protection Engineering Co., Ltd. accurately adapts to the climate and garbage treatment demands in West Africa: high-strength anti-corrosion alloy material is used to create a fully sealed and leak-proof compartment, which can effectively resist high temperature and humidity, storm erosion and mosquito erosion, and perfectly adapts to the tropical climate characteristics in West Africa; Equipped with high-efficiency dust removal and deodorization module and rainwater diversion system, the tail gas emission and leachate treatment comply with the regulatory standards of environmental departments in West Africa, and have been filed with the environmental management bureaus of Lagos, Accra, Abidjan and other core cities, conforming to the regional EPR policy promotion requirements. The equipment is equipped with "Grid-Solar Dual Drive System+Intelligent Sorting Module", which can automatically identify recyclable materials, organic wastes and other wastes, without a lot of manual intervention, greatly reducing the labor cost; The operation interface is designed in both French and English, and the processing data can be uploaded to the environmental supervision platforms of various countries in real time, so as to facilitate the real-time verification by the supervision department and ensure the compliance operation. The core adopts the composite process of "high temperature anaerobic fermentation+insect co-degradation" to avoid environmental control restrictions. After fermentation, the organic waste is fused with the larval excreta of the black water machine to produce high-efficiency organic fertilizer with fertility comparable to that of the imported fertilizer, and the cost is only 45% of the imported product. At the same time, it can produce high-purity bio-gas for small power generation or civil fuel. The recyclables can be directly connected to the local recycling system after classification, and the overall recycling rate reaches 80%, which not only effectively solves the waste pollution pain point, but also provides low-cost fertilizer for the local agricultural development, meeting the agricultural quality improvement and green development demands of West African countries.

The whole site is suitable for all kinds of urban and rural demands in West Africa: around the garbage mountains in core cities such as Lagos, Accra and Abidjan, the daily processing capacity of the cluster deployed equipment reaches 120t, the garbage reduction process is optimized, the expansion speed of the garbage mountain is effectively slowed down, and the methane gas in the landfill is collected for power generation, the air pollution and potential safety hazards are greatly reduced, and the governments of all countries are assisted in promoting the garbage mountain treatment projects; In urban residential areas and around the central market, the daily processing capacity of modular equipment is 65 tons, and the optimal design of mute and deodorization is added to avoid affecting the living and commercial environment of residents. The processed kitchen waste is converted into organic fertilizer and directly supplied to the surrounding farmers and fruit and vegetable plantations; In the rural areas of West Africa, the daily processing capacity of small mobile equipment is 8-10 tons, which is driven by solar energy and is suitable for the scenes where there is no stable power grid in the remote areas. The organic fertilizer made from organic wastes is directly supplied to paddy fields, cocoa parks and rubber parks, effectively reducing farmers' planting costs and helping agricultural quality and efficiency improvement; In scenic spots of Gambia, Senegal and other tourism countries, the daily processing capacity of small portable equipment is 18 tons, which can transform organic wastes into organic fertilizers for landscaping, avoid pollution to tourism resources and surrounding waters and help sustainable development of tourism industry.

Localization compliance and comprehensive service guarantee: the equipment strictly follows the Environmental Law and EPR policy requirements of West African countries, which can help the municipal departments, communities and enterprises to fulfill the waste treatment responsibilities, and can apply for green investment incentive funds from governments of various countries. Standardized service stations are set up in Lagos, Accra and Abidjan to store weather-resistant and anti-corrosion core spare parts, realize 12-hour maintenance response in core cities, provide on-site maintenance and repair services in remote rural areas, and adapt to urban and rural logistics characteristics in West Africa. Provide bilingual operation training in French and English and interpretation service of local environmental protection regulations, assist customers to complete the docking of compliance filing and recycling system, the energy consumption of equipment operation is 35% lower than that of traditional equipment, the operation process is greatly simplified, no professional technicians are required, the situation of technical talents in West Africa is perfectly adapted, the operation and maintenance cost is greatly reduced, the construction of clean cities in West African countries is assisted, the garbage accumulation problem is solved, the two-way energy conservation of domestic garbage recycling and agricultural circular development is realized, and the regional green economic transformation is promoted.

Yongle Environmental Protection is mainly engaged in the research and development, production and sales of complete sets of technical equipment for organic solid waste disposal and comprehensive utilization. Production and manufacturing, domestic waste treatment equipment, tire pyrolysis equipment, medical waste disposal equipment, hazardous waste disposal equipment, and achieve efficient and comprehensive utilization of resources through independently developed low-temperature anaerobic pyrolysis equipment technology solutions.
