Construction and demolition waste contains in large quantities asphalt, bricks and concrete (known as ABC). Asphalt paving materials can be crushed and reassembled with aggregates and emulsifiers to make new pavements, or used as gravel bedding in road or embankment construction; bricks and concrete can be used as recycled sand and aggregate after crushing and removing reinforcement, and it has a wide range of applications in various construction projects; the powder produced during the recycling process can be used in a variety of areas, such as building filler, manufactured soil, etc.Construction and demolition waste recycling equipmentGEP Ecotech offers crushers, shredders, screening and conveying equipment for the recycling of construction and demolition waste. We have mobile and stationary versions available.Shredder or crusher?Generally speaking, construction and demolition waste contains large amounts of medium to high hardness materials such as concrete, asphalt, masonry and rubble, which are best
Solid waste is fed into the shredding plant using a belt or feeder to reduce the material to the required size. For most materials, a twin or four-shaft shredder can be used to process the material to the target size in one pass; for piles or bales, a pre shredder can be used to increase production and reduce the wear and tear on the core equipment. Use of an iron remover to remove ferrous materials and windrow or other equipment to remove other materials that cannot be burned. Pressing the material into pellets or lumps (optional).
The disposal of industrial waste revolves around volume reduction, reuse and recycling. Depending on the characteristics of the material, a multi-stage shredder or crusher is used to reduce the volume of the material; a separator such as an iron separator is used to separate the reusable metals such as iron, aluminium, copper and zinc; other materials can be separated and recycled, some high calorific value materials can be produced as fuel and other worthless materials can be sent to landfills. GEP Ecotech offers integrated industrial solid waste disposal systems that are not only suitable for specialised solid waste disposal centres, but are also used by companies that generate large quantities of industrial solid waste.
GEP ECOTECH delivered a high-performance bulky waste disposal system with a capacity of ≥8 t/d for a leading environmental protection company in Anhui. The project tackles key challenges of urban bulky waste—large volume, heavy weight, and mixed soft-hard materials that often cause jamming in conventional shredders. To solve this, GEP ECOTECH provided the hydraulic twin-shaft shear shredder (GH10) with chain conveyor, belt conveyor, magnetic separator, and pulse dust removal system. This tailored configuration fully reflects GEP ECOTECH's core strengths: deep understanding of complex waste streams, proven anti-jamming and anti-winding technology, durable high-alloy steel cutters for extended service life, and intelligent GI system enabling real-time monitoring and automatic fault protection. The result is energy-efficient, dust-free, fully automated operation, significantly reducing volume and preparing iron and light materials for incineration.
Specially designed for a leading environmental engineering firm in China, this project processes bulky waste such as mattresses, sofas, and green waste at 4–6 t/h, with output size of around 200–300mm. The system adopts a metal chain conveyor to feed a low‑speed, high‑torque dual‑shaft shredder for primary shredding, then a belt conveyor moves material to a magnetic separator for iron removal, with remaining fractions sent off‑site for incineration; an intelligent dust removal system keeps the plant clean. By significantly reducing landfill volume and converting bulky waste into combustible fractions with valuable scrap iron recovered, this solution turns urban bulky and green waste into a cleaner energy source, supporting circular economy and easing the burden on landfills. According to the client: "The most stable system we have ever used—less jamming, less downtime, and GEP ECOTECH's rapid‑response support made commissioning seamless."
