Processing of Heterogeneous Waste Streams by NIR Sorting - Reflections on the Material-Specific Recovery based on selected M(B)T-Waste Streams -

Especially in case of heterogeneous waste streams which cannot be reused or material recycled Waste-to-Energy (WtE) is one particularly interesting option. Waste material used as energy resource, e.g. in industrial co-incineration as Solid Recovery Fuel (SRF) in order to replace fossil fuels, needs to be processed to meet certain quality criteria (e.g. in terms of fuel properties as well as the chlorine and heavy metal content). Being the reason for this to avoid negative influences on the co-incineration process as well as the product quality in the case of the cement industry and to secure that environmental standards are not being compromised. During the last years in Europe the biogenic carbon content of the waste streams to be co-incinerated has gained in importance as a determining criterion for the energetic recovery of waste due to legal obligations and resulting economic considerations (EU’s CO2 emission trading scheme).

The required processing demands - material-specific splitting of heterogeneous waste - in order to allow for an optimized routing of resulting waste streams can potentially be met by the use of sensor-based sorting technologies, which are already state-of-the-art for the treatment of separately collected recyclables which are rather homogeneous in their composition. According to Faist & Ragossnig as well as Titech practical results show that the implementation of NIR (Near-infrared) sensor-based sorting is capable of splitting also heterogeneous wastes by material-specific characteristics and allows for generating waste streams that can be recovered.

Like all public international law treaties, the Paris Climate Accords rely on national law for their implementation. The success of the agreement therefore depends, to a large extent, on the stepstaken or not taken by national governments and legislators as well as on the instruments and mechanisms chosen for this task. Against this background, the present article compares different approaches to the implementation of the Paris Agreement, using court decisions as a means to assess their (legal) effectiveness.
