HISER FINAL CONFERENCE Circular economy of gypsum plasterboard

SLIDE 2

Plasterboard waste

PRECONSUMER -> CLEAN, FAST AND EXCELLENT TRACEABILITY POST-CONSUMER -> DIRTY, NO TRACEABILITY

SLIDE 3

Major recycling scheme in EU

SLIDE 4

Review of separation techniques

SLIDE 5

Previous sorting

SLIDE 6

To develop onsite recycling equipment:

SMALL- MEDIUM EQUIPMENTS

BIG EQUIPMENT

SCALABLE
DELIVERED TO CONSTRUCTION SITES
HIGH RATE CAPACITY/CONSUMPTION
HIGH CAPACITY
COST: 1,5M€-2M€
HIGH PURITY RATES

New recycling concept

SLIDE 7

Investment cost: 24.000€

SLIDE 8

Purity vs grain size distribution

TARGET: <8mm

SLIDE 9

Combined with sensor sorting

Passage fraction: plasterboards Active fraction: ejected impurities

Knauf‘s recycling system

Recycled material: PAPER Recycled material: GYPSUM

NIR spectroscopy has been explored to detect inline and sort out improper materials

contained in (crushed and sieved) postconsumer plasterboards streams collected separately in C&D works:

SLIDE 10

New plasterboards with recycled gypsum

INCREASES UP TO 10% OF RECYCLED GYPSUM DOES NOT SIGNIFICANTLY AFFECT STRENGTH NOR E-MODULUS. Recycling content during the manufacturing process affects the mixture and additives should be readjusted.

SLIDE 11

Manufacturing, installation and monitoring

1500x650x15mm 3000x3000x2400mm

Installation of plasterboards (conventional and recycled) for interior walling
Monitoring under real conditions: temperature, heat flow, power consumption,

humidity.
