This is a mind map created using a visual thinking tool, focusing on the central concept of "MATERIALI" (Materials). The map branches out into several key areas to provide a comprehensive overview. First, it introduces the concept of "sostenibilità" (sustainability), defined as a principle that wants to guarantee future generations the same level of well - being by using natural resources without exceeding the planet's capacity. This is linked to the Life Cycle Assessment (LCA), which evaluates the entire life cycle of a product, including raw material consumption, energy consumption, environmental impact, economic impact, and end - of - life analysis. Next, the map classifies materials into "naturali materie prime" (natural raw materials) and "artificiali" (artificial materials). Natural raw materials are further divided into animal, vegetable, and mineral regions, each with specific examples. Artificial materials are categorized as either renewable (Vr >> Vc) or non - renewable (Vr << Vc), with examples provided for each. The map also details the "ciclo di lavorazione" (processing cycle), which includes stages such as raw material extraction, local processing, transport, semi - finished product processing, manufacturing/object finishing, reuse, recycling, and disposal (including thermal valorization). Each stage is clearly defined, showing the flow of materials through the production process.

Questa mappa mentale, realizzata con EdrawMind, illustra il ciclo vitale della carta, partendo dalla materia prima (legno, derivato dalla deforestazione) e le sue soluzioni sostenibili: colture a rapido accrescimento e dedicate (pioppi, betulle, abeti, faggi, aceri) e il riciclo della carta. Vengono analizzati il processo produttivo (macchina continua, basato sulle paste come sostanze fondamentali) e i diversi utilizzi della carta: grafico, imballaggio, domestico e industriale, oltre alla tipologia di materiale artificiale alternativo. È un modello riutilizzabile per lezioni di scienze ambientali e studi sulla sostenibilità dei materiali.
