With the accelerated urbanization process in Kenya, the construction boom and renewal of core cities such as Nairobi, Mombasa, and Kisumu have generated massive urban waste—concrete blocks, masonry fragments, scrap steel from building demolition, smelting slag and gangue left over from industrial production, and old building materials eliminated in urban renovation, piling up at a scale of millions of tons annually. These wastes not only occupy valuable urban land resources but also easily cause dust pollution, soil and water damage, becoming an "environmental burden" restricting sustainable urban development. At the same time, Kenya's infrastructure industry has a sustained rising demand for sand, gravel aggregates, and recycled building materials. Restrictions on natural sand and gravel mining have led to an expanding raw material gap and rising prices. How to transform "urban waste" into "green gold" and achieve a win-win of environmental protection and profitability has become an important issue for Kenya's urban development. Focusing on the field of urban waste resource utilization, DongMeng brings a full-chain recycling solution of "crushing-sorting-recycling", revitalizing urban waste with new value and injecting strong momentum into building green and low-carbon cities in Kenya.

Full-Chain Recycling Equipment: Precisely Solving Urban Waste Treatment Pain Points

Urban waste in Kenya is complex in composition and diverse in form, mostly concentrated in densely populated urban areas or narrow demolition sites. Traditional treatment methods have problems such as "high transportation costs, low recycling rates, and serious pollution". DongMeng has tailored a flexible and efficient full-chain recycling equipment system to achieve "on-site treatment, precise sorting, and high-value recycling", perfectly adapting to urban operation scenarios.

The core treatment equipment is a tracked mobile crushing station, which can directly drive into waste accumulation sites for on-site operation, eliminating the need for long-distance transportation of waste, greatly reducing transportation costs and carbon emissions. The equipment adopts a modular design, which can be flexibly matched with jaw crushing modules (primary crushing) and impact crushing modules (tertiary crushing). The crushing cavity is optimized for hard waste such as concrete blocks and masonry, with a large crushing ratio and uniform discharge, capable of producing recycled aggregates of different specifications from 3mm to 31.5mm to meet diverse recycling needs. Targeting impurities such as scrap steel, plastic, and wood mixed in the waste, the equipment is equipped with an intelligent sorting system integrating triple technologies of magnetic separation, infrared identification, and air separation: the magnetic separation device can efficiently separate scrap steel with a recovery rate of over 98%; the infrared identification system accurately identifies non-metallic impurities such as plastic and rubber and sorts them automatically; the air separation device separates light dust and aggregates according to material specific gravity, ensuring the purity of recycled aggregates exceeds 95%.

Environmental performance fully meets urban standards: the equipment adopts a fully sealed crushing cavity and screening system, combined with a pulse dust removal device, with a dust emission of ≤8mg/m³, far lower than Kenya's urban environmental limits; the optimized noise reduction structure and muffler device control the operation noise within 75 decibels, which can operate around residential areas without affecting residents' lives; some models support electric drive mode with zero exhaust emissions, perfectly aligning with urban green operation requirements. In terms of capacity, the equipment covers a processing range of 50-300 tons per hour, and single machines or multi-machine linkage can be flexibly configured according to the scale of urban waste generation to achieve large-scale recycling and treatment.

High-Value Recycling Applications: Waste Turns into "Popular Building Materials" with Considerable Profits

Recycled products produced by DongMeng's recycling solutions are highly competitive in the Kenyan market due to their stable quality and diverse uses, making "treating waste" a new track for "creating wealth".

Recycled aggregates are the core profit point: recycled aggregates with a particle size of 10-20mm can be directly used for the construction of urban road bases and subbases, replacing natural sand and gravel, reducing costs by more than 35%, and indicators such as strength and wear resistance fully meet Kenya's road construction standards. They have been adopted in major projects such as the Nairobi Ring Road and Mombasa Port Expansion; recycled aggregates with a particle size of 5-10mm can be used for producing recycled concrete and mortar, suitable for building masonry, wall plastering and other scenarios, and are deeply favored by local construction enterprises; fine aggregates with a particle size of 3-5mm can be processed into new building materials such as permeable bricks, sidewalk bricks, and slope protection bricks, which are regular in appearance and have good water permeability and air permeability, meeting Kenya's "sponge city" construction needs. The market price is 20%-40% higher than that of ordinary natural sand and gravel.

Sorted and recycled scrap steel can be directly sold to steel processing plants for recycling after remelting; waste plastic, waste wood, etc. can be classified and recycled to professional treatment enterprises to achieve secondary profits. It is estimated that a DongMeng recycling production line with a daily processing capacity of 800 tons of construction waste can achieve a net annual profit of millions of yuan after deducting costs such as energy consumption, labor, and maintenance, with an investment payback period of only 10-16 months. In addition, to promote the development of the environmental protection industry, the Kenyan government has introduced a number of supportive policies—providing 5-7 years of tax relief for waste resource utilization enterprises, and recycled building materials enjoy priority procurement rights in government bidding projects, further expanding the project's profit space.
