Energy Treasure: Re evaluation of the Value of Light Materials in Decoration Waste
About 30% of the light materials in decoration waste, such as wood, plastic, fabrics, etc., contain enormous energy value. These combustibles can be scientifically processed and converted into solid recycled fuel (SRF) and waste derived fuel (RDF), with a calorific value of 3500-6000 kcal/kg, close to the level of coal. This transformation not only reduces the land resources occupied by landfilling, but also reduces 1.5 tons of carbon emissions per ton of RDF, which is equivalent to the carbon sequestration capacity of planting 15 adult fir trees. From an economic perspective, the cost of alternative fuels is only one-third of that of standard coal. If combined with government subsidies (such as nearly 100 yuan per ton of RDF subsidy in Guangdong Province) and carbon trading benefits (about 150 yuan per ton of emission reduction value), enterprises can achieve a 25% -30% reduction in fuel costs, with significant economic benefits.
Natural Advantage: Widely Distributed 'Alternative Fuel Granary'
Decoration waste, as an alternative fuel, not only has a rich combustible content and outstanding carbon reduction ability, but its widespread distribution is also a major advantage. Unlike high calorific value industrial solid waste concentrated in developed areas, decoration waste is distributed throughout every city and street in the country. This "ubiquitous" characteristic makes it a natural "alternative fuel granary". Enterprises can use local materials to process decoration waste, significantly reducing logistics costs and energy consumption, providing convenient conditions for the large-scale application of alternative fuels.
Technological breakthrough:GEP ECOTECH's efficient conversion solution
Faced with the industry pain points of complex composition and difficult sorting of decoration waste,GEP ECOTECH's independently developed decoration waste light substance alternative fuel preparation system achieves efficient conversion from waste to fuel through the process of "multi-stage crushing+intelligent sorting+compression molding":
1. Multi stage crushing homogenization
Adopting a double-shaft shredder for primary coarse crushing, equipped with CrNiMo high alloy cutting tools to ensure stable and efficient crushing; Then, secondary fine crushing is carried out through a single rotor fine shredder to grind the material to the appropriate particle size and improve the looseness of light materials.
2. Intelligent sorting and purification
The priority process of magnetic separation can achieve a metal recovery rate of≥98% and thoroughly remove metal impurities that affect combustion efficiency; The wind selection efficiency enhancement technology separates heavy substances such as gypsum and broken bricks, effectively ensuring fuel purity and improving fuel quality.
3. Flexible molding solution
The final product can be made into bulk SRF or rod-shaped RDF according to actual needs, which can be directly adapted to scenarios such as incinerators and cement kilns. At the same time, the system adopts a modular design that can be flexibly customized, suitable for processing scenarios of different scales from small transfer stations to large comprehensive processing centers.
When the wood chips and plastics in the decoration waste release energy in the cement kiln, and when fabrics and foam become the green driving force for urban heating, what we see is not only the rebirth of waste, but also a profound transformation related to resource recycling, energy security, and industrial upgrading.
