WHY RECYCLING MATTERS

Why Recycle Construction Waste?

Construction waste should not be treated only as material to dump. In many demolition and redevelopment projects, concrete, brick, asphalt, and masonry can be processed into reusable aggregate. That means less landfill pressure, lower disposal cost, shorter hauling distance, and more value recovered from every jobsite.

♻️

Reduce Landfill Pressure

Large demolition volumes quickly fill landfill space. Recycling keeps a major share of concrete and masonry waste out of dumping yards.

🚛

Lower Disposal and Hauling Cost

When waste is processed closer to the site, contractors spend less on truck transport, tipping fees, and repeated waste handling.

🧱

Produce Reusable Aggregate

Processed output can go back into road base, backfilling, sub-base, and other practical uses instead of remaining zero-value debris.

🏙️

Meet Cleaner Project Requirements

Urban projects increasingly need cleaner demolition, better dust control, and visible recycling results. A recycling line directly supports that goal.

PROCESSING FLOW

Detailed C&D Waste Processing Flow

Construction waste is difficult because the feed is mixed, variable, and contaminated. Concrete with rebar, brick, asphalt, wood, plastic, soil, and fines may all arrive in one batch. The processing flow therefore has to do more than crush — it must sort, protect equipment, control dust and noise, and still deliver usable recycled aggregate.

Challenge module

Main processing difficulties on demolition sites

Unlike natural rock, C&D waste changes from truck to truck. Before the line can create saleable recycled aggregate, it has to survive unstable feed, remove contamination, and keep the site under control.

Rebar, steel, and oversized slabs

Large reinforced concrete blocks can damage downstream machines if they are not opened first by a jaw crusher and followed by magnetic separation.

Wood, plastic, gypsum, and light contaminants

Mixed waste reduces aggregate quality. Pre-sorting and staged separation are needed before final screening and stockpiling.

Dust, noise, and urban operating restrictions

Demolition projects often run close to roads, residential blocks, or commercial sites, so suppression, enclosure, and compact layout planning matter as much as capacity.

Temporary land and unstable utilities

The line often has to be installed on short-term sites with limited foundation work and uncertain power access, which is why mobile equipment is usually the safer choice.

Solution module

From mixed debris to reusable aggregate

The typical SUNREX flow is not built around one crusher alone. It starts with jaw crushing as the main opening stage, adds impact crushing when mixed waste needs more liberation, and combines separation, screening, recirculation, and dust-control equipment into one practical recycling line.

Pre-sorting and controlled feeding

Sorting + Hopper

Excavators or loaders remove visible steel bars, timber, plastic sheets, and oversized trash before material enters the hopper.

Protects the crusher from uncrushable items and tangled rebar
Reduces contamination before size reduction starts

Primary jaw crushing

Jaw Crusher

The jaw opens large concrete blocks and demolition slabs into a manageable size range for downstream cleanup and shaping.

Best choice for reinforced concrete and heavy feed
Creates a stable feed for either screening alone or a following impact crusher

Magnetic separation and trash removal

Magnet + Manual Check

Ferrous metal is pulled out after primary reduction, while operators remove remaining light contaminants or oversized foreign objects.

Improves finished aggregate cleanliness and protects secondary equipment
Recovered steel can be sold as scrap for extra value

Secondary impact crushing when needed

Impact Crusher

For mixed C&D waste or when better particle shape is required, the impact crusher liberates attached mortar and reduces brick or concrete further.

Preferred over cone crushing in most construction waste projects
Helps produce better recycled base and graded aggregate

Multi-deck screening and recirculation

Screen + Return Loop

The screen separates recycled aggregate into required size bands while oversize returns automatically for another pass.

Supports 0–5 mm fines, 5–10 mm, 10–20 mm, and base material outputs
Lets the plant adjust finished sizes around local recycling specifications

Stockpiling, suppression, and dispatch

Final Control

Separated products are stockpiled or loaded directly, with dust suppression, water spraying, and traffic control maintained across the site.

Helps keep the project compliant in urban or temporary operating areas
Delivers saleable recycled aggregate with cleaner site management

WHEN MOBILE MAKES SENSE

Four Scenarios Where Mobile Lines Are the Natural Fit

Mobile and fixed plants are both viable options for C&D waste processing. The difference is operational context. If any of the following scenarios describes your project, a mobile configuration is worth looking at closely.

🚚

The Site Is Temporary or Will Move

When demolition contracts are time-bound and the team relocates to the next job, a mobile line moves with them — no permanent installation to abandon, and no need to truck remaining waste off-site.

⚙️

Feed Composition Changes Frequently

C&D waste is rarely consistent — concrete, brick, tile, and asphalt often arrive in the same load. Mobile jaw-plus-impact setups handle that variability without redesigning the layout each time the feed changes.

🏙️

The Project Is in or Near a Built-Up Area

Compact mobile layouts reduce long-distance trucking and keep the processing footprint small — which matters when operating under urban dust, noise, and traffic restrictions on temporary or leased land.

🔋

Grid Power Is Not Confirmed

In redevelopment zones or phased projects where stable grid access is not yet in place, a diesel-capable mobile plant lets the recycling line start on schedule without waiting for electrical infrastructure.

MOBILE VS FIXED

Match Your Plant Type to Your Project Model

Both mobile and fixed plants are proven solutions for C&D waste recycling — the choice depends on how your project is organised. The comparison below covers the factors that typically determine which configuration is the right fit.

Mobile Recycling Plant

Well suited to demolition contractors, multi-site operators, and urban jobs where land is temporary and infrastructure is not yet in place.

Common C&D Choice

RelocationFast transfer, no teardown cost

Civil workMinimal or no permanent foundation

Urban complianceCompact layout, less truck movement

Power sourceGrid or diesel generator set

Deployment speedDays, not months

Processes waste on-site, reducing hauling cost and public road load
No land lease lock-in — plant departs when the demolition contract ends
Diesel-capable units can start before grid connection is confirmed

Fixed Recycling Plant

A strong option when waste from multiple sites is aggregated to one long-term yard with secured land, stable utilities, and centralised dispatch.

Centralised Yard Model

RelocationDesigned for permanent installation

Civil workFoundation and infrastructure included

Urban complianceRelies on permanent site approval

Power sourceRequires stable grid connection

Deployment speedLonger lead time for civil work

Higher throughput potential when feed volume is large and consistent
Purpose-built layouts can integrate more sorting, washing, and product lines

Recommended Jaw / Jaw + Impact

Mobile C&D Recycling Train

Best for demolition contractors, temporary urban jobs, and multi-site projects that need a complete recycling process line rather than only one crusher model.

Core crushing logic Jaw crusher as the primary opening stage, with impact crushing added when mixed waste needs more liberation and shaping.

Typical throughput 80–300 t/h, depending on feed mix, contamination level, and whether the line is all-in-one or modular.

Power & site fit Low civil work, fast relocation, and flexible supply from grid power or a diesel generator set.

Target throughput	Main machine combination	Applicable feed	Typical finished output	Supporting modules	Selection note
80–120 t/hEntry mobile line	SNE600-1 + SNF1214S-2 + SNS1860-1 GF0936 feeder / PE600×900 jaw / PFW1214III impact / 3YK1860 screen	Concrete-heavy feed, limited brick content, low-to-medium contamination, and rebar already reduced by front-end manual sorting.	Typical controlled output: 0–5 mm fines / 5–20 mm recycled aggregate / 20–40 mm sub-base, with oversize returned when cleaner grading is needed.	Receiving hopper, manual pre-sorting point, overband magnet, return conveyor, discharge conveyors, spray or mist suppression, diesel generator set or grid hook-up.	Best for smaller city jobs that still want a jaw + impact logic. The installed machine capacity stays above the target output so the line can run more steadily on contaminated C&D feed.
130–180 t/hMainstream mobile contractor range	SNE750-1 / SNC106-1 + SNF1214S-2 / SNF1315S-2 + SNS1860-1 GF1245 feeder / PE750×1050 or C106 jaw / PFW1214III or PFW1315III impact	Mixed C&D feed, balanced concrete and brick content, asphalt fragments, and medium contamination after metal removal.	Typical saleable fractions: 0–10 mm fines / 10–20 mm recycled aggregate / 20–40 mm base material, with output split adjusted by screen media and return ratio.	Heavy receiving hopper, picking belt, overband magnet, return conveyor, transfer conveyors, water spray system, mobile stockpile belts.	Choose this range when the customer needs a real sales-grade recycled aggregate layout, not only waste volume reduction on site.
180–250 t/hHigher-output mixed waste line	SNC106-1 + SNF1315S-2 + SNS2160-1 GF1245 feeder / C106 jaw / PFW1315III impact / 3YK2160 screen	Mixed urban demolition feed, concrete-heavy but variable, with brick, asphalt, mortar, and stricter cleanliness requirements for downstream recycled products.	Typical finished output: 0–5 mm / 5–20 mm / 20–40 mm, plus oversize recirculation for tighter grading and better liberation.	Pre-sort hopper, overband magnet, longer picking conveyor, return conveyor, transfer conveyors, enclosed loading point, spray suppression, diesel generator option.	This is the practical modular range when the project sells several recycled aggregate grades and needs steadier quality from one mobile line.
250–300 t/hHeavy modular mobile line	SNC110-1 + SNF1315CS + SNS2160-1 GF1245 feeder / CX110 jaw / PFW1315II impact / 3YK2160 screen	Large redevelopment packages, high-volume concrete-heavy feed, and broader mixed site intake where relocation is still required after each project stage.	Typical finished output: 0–5 mm fines / 5–20 mm recycled aggregate / 20–40 mm sub-base, with recirculated oversize for higher target-size yield.	Heavy-duty receiving hopper, manual sorting station, overband magnet, long transfer and stockpile conveyors, multiple spray points, diesel generator or hybrid power support.	Choose this only when daily tonnage is high enough to justify a heavier modular fleet and the customer still needs mobile deployment instead of a permanent yard.

Long-term yard Jaw / Jaw + Impact

Fixed C&D Recycling Line

Suitable for a permanent municipal recycling yard or an industrial recycling park where utilities, foundations, and approvals are already secured.

Core crushing logicJaw crushing remains the primary opening stage, with impact crushing added when mixed waste or higher finished quality requires it.

Typical throughput80–300 t/h, with more space for sorting, longer conveyors, larger stockyards, and centralized utilities.

Power & site fitStable grid power, heavier civil work, centralized control, and stronger long-term yard planning.

Target throughput	Main machine combination	Applicable feed	Typical finished output	Supporting modules	Selection note
80–120 t/hCompact fixed recycling yard	PE600×900 jaw + PF1214 impact + vibrating screen Impact stage can stay optional for cleaner concrete-heavy feed	Concrete-heavy feed, low brick ratio, lower contamination, and stable intake from one municipal or contractor recycling point.	Typical fixed output: 0–5 mm fines / 5–20 mm recycled aggregate / 20–40 mm sub-base, or one blended road-base product when grading demand is simpler.	Receiving hopper, vibrating feeder, manual sorting platform, overband magnet, transfer conveyors, product conveyors, spray suppression, electrical cabinet and basic centralized control.	A good fixed starting line when the yard wants low-to-medium output with manageable investment.
130–180 t/hStandard fixed jaw + impact line	PE750×1060 jaw + PF1315 impact + 3-deck vibrating screen The mainstream fixed range for regular recycled aggregate output	Balanced mixed C&D feed, concrete + brick combinations, medium contamination, and stable front-end magnetic separation.	Typical saleable fractions: 0–5 mm fines / 5–20 mm recycled aggregate / 20–40 mm base material, with oversize recirculation for tighter grading.	Receiving bin, vibrating feeder, picking cabin or manual sorting belt, overband magnet, return conveyor, transfer conveyors, stockpile conveyors, dust suppression line.	This is the most practical fixed sales option when the customer wants steady output and cleaner fractions without building a full central recycling park at the first stage.
180–250 t/hHigher-volume fixed mixed-waste line	C106 jaw + PFW1315III impact + 3-deck vibrating screen Jaw-first line for stronger liberation and more stable long-hour running	Mixed urban demolition feed, concrete + brick + asphalt, mortar-bearing material, and stricter product cleanliness targets for recycled aggregate sales.	Usually configured for 0–5 mm / 5–20 mm / 20–40 mm output, plus recirculated oversize when the customer needs tighter finished grading.	Heavy receiving hopper, vibrating feeder, longer sorting conveyor, overband magnet, manual cleanup point, stockyard conveyors, spray suppression, MCC or centralized control cabinet.	Choose this range when the business model is long-hour yard operation, multi-grade finished product sales, and more consistent downstream quality control.
250–300 t/hCentral recycling park line	C106 / C116 jaw + PFW1315III / PFW1415 impact + heavy-duty vibrating screen High-throughput fixed line for larger municipal or industrial recycling parks	Centralized truck-fed feed, broader mixed city waste streams, and larger yards that process concrete-heavy loads together with brick-rich and asphalt-containing material.	Typical multi-stockpile output: 0–5 mm fines / 5–20 mm aggregate / 20–40 mm recycled base, with oversize sent back for another crushing pass.	Sorting cabin, overband magnet, multiple transfer conveyors, recirculation loop, dust suppression or enclosure points, transformer, MCC, control room, loading and stockyard system.	Suitable only when permanent civil work, centralized utilities, and long-term site approvals are already justified by the yard business model and dispatch volume.

COMMON QUESTIONS

Frequently Asked Questions

Below are the questions we hear most often from contractors, recyclers, and city waste operators evaluating mobile versus fixed construction waste lines.

What types of construction waste can be processed?

SUNREX jaw-only or jaw-plus-impact recycling lines process reinforced concrete, brick, tile, asphalt millings, and mixed demolition debris. The flow can include hand sorting, magnetic separation, and multi-deck screening to remove steel, wood, plastic, and fines before final stockpiling.

Do construction waste projects usually need a cone crusher?

Usually no. Most construction waste projects use a jaw crusher alone or a jaw plus impact combination. Cone crushers are uncommon because C&D feed is mixed, variable, and often contains rebar or attached mortar; impact crushing is typically better for liberation and recycled aggregate shaping.

What is the recovery rate for recycled aggregate?

Typically 80–92% of input material becomes sellable aggregate. Remaining fines (0–3 mm) can be used for embankment or returned to processing. Metal recovery systems capture reinforcement steel for scrap value.

Can recycled aggregate meet construction standards?

Yes. Screened recycled aggregate meets local construction specs for road base, landscape use, and lower-grade concrete. Certification depends on input material source and processing cleanliness.

How fast can a site be cleared?

Mobile plants process 100–200 t/h. A 10,000-ton demolition site can typically be cleared and processed within 5–10 weeks, depending on material composition and site access.

What dust control measures are in place?

SUNREX plants include integrated spray systems, enclosed discharge areas, and fabric filters on crusher exits. Air quality monitoring and real-time misting keep dust within regulatory limits.

What is the profitability of construction waste recycling?

Recycled aggregate typically sells for ¥20–50 per ton. At 80+ t/h throughput, gross revenue can reach ¥160–400k per day. Net margin is usually 30–50% after fuel, labor, and equipment maintenance.
