La miniera di Chuquicamata

Il video che mostravo (tratto da una puntata di Ulisse, il piacere della scoperta) descriveva le operazioni di estrazione nella miniera a cielo aperto di Chuquicamata, uno dei più grandi giacimenti di rame in Sudamerica.

I ragazzi apprezzavano l’imponenza dei mezzi utilizzati per le operazioni, camion grandi come case di tre piani, che spiegano molto bene le dimensioni delle operazioni.

Esempi virtuosi: acciaio e alluminio

According to industry estimates, paper can be recycled an average of 4 to 6 times. Each time recycling occurs, the fibres become shorter and weaker and virgin pulp must be introduced into paper production to maintain the strength and quality of the fibre. Through this process, recovered paper and forest-based product complement each other ecologically and economically.

Unlike metals, recycling usually affects the physical properties of plastics to some extent. This makes it difficult to recover large amounts of certain types of plastics for use in the same applications that they were originally produced for. Thanks to intensive research and technological developments made by recycling companies, recycled plastic can be used in almost as many applications and products as those using virgin materials.

We now use about 20 times more plastic than we did 50 years ago and certain post-consumer products contain as many as 20 different types of plastic materials.

Tyres are one of the most versatile recycled materials and are used as fuel or for numerous innovative applications, such as construction and civil engineering.

The electronics recycling industry in the USA alone is worth more than US$ 20bn and processes over 4m tonnes each year, providing direct and indirect employment for 45,000-plus people. Recycling copper uses much less energy, about 10 million Btu/tonne, than the energy required to extract copper from copper ore at about 95 million Btu/tonne. Recycling copper saves up to 85% of the energy used in primary production, and so by using copper scrap, we reduce CO2 emissions by 65% Recycling one tonne of steel saves 1,100 kilograms of iron ore, 630 kilograms of coal, and 55 kilograms of limestone. One tonne of recycled aluminium saves up to 8,000 kilograms of bauxite, 14,000 kWh of energy, 40 barrels (6300 litres) of oil, 238 million Btu’s of energy. Recycling 1 tonne of aluminium avoids the emission of about 9 tonnes of CO2 emissions as recycling aluminium uses 95% less energy than producing aluminium using raw materials. Recycling one tonne of tin saves 99% of the energy required for the primary production of tin.

EcoInvent Database

It is difficult to know what materials electronics is made of (list of materials in microchip not known or not disclosed, electronics evolve fast).

The ecoinvent database provides well documented process data for thousands of products, helping you make truly informed choices about their environmental impact.
