Effective Recycling Methods for Various Waste Materials
Recycling of Various Materials
Paper and Paperboard Recycling
Recycling paper and paperboard constitutes 20-25% of Municipal Solid Waste (MSW). A considerable portion ends up as waste or is incinerated, which is environmentally and economically undesirable.
Paper, due to its high cellulose content, should be considered a raw material for manufacturing new paper. The cost of recycled paper production is lower, requiring less water and energy than production from wood. Technically, obtaining paper from

Geological Events, Dating Methods, and Fossilization
Geological Events and Dating
Sequence of Events
To order past geological events chronologically, we use the principles of horizontality and superposition of strata. Another approach is the principle of cross-cutting relationships. This principle states that anything that affects geological materials and structures is post-dated to them. Because it establishes the order in which events unfold, it’s also called the principle of succession of events.

Advantages of Ventilated Facades
Ventilated constructions offer thermal, aesthetic, and waterproofing benefits to buildings. They prevent overheating in summer, provide water protection, and allow vapor diffusion from the inside to the outside. This ensures optimal moisture regulation and makes it easy to adapt to current and future energy standards. Ventilated facades also offer endless design possibilities.
Air Gap
The air gap should be a minimum of 25mm and as much as necessary, provided there
