What is it about?

Raw materials are unprocessed raw materials extracted from nature that are either consumed immediately or sent for industrial processing. There are renewable raw materials such as wood, water or animal products, which are constantly replenished by nature, and non-renewable raw materials such as metals and minerals, which are only available in limited quantities and may one day run out for good.

Primary raw materials are raw materials that have not been processed apart from their extraction, such as fresh wood fibres from felled trees for paper production or natural rubber for tyre production. Secondary raw materials, on the other hand, are obtained by recycling discarded or used products, such as wood fibres from waste paper, compost from plant waste or rubber granulate from used tyres. Secondary raw materials help to avoid waste and conserve the earth's limited natural resources.

Introduction: Video clip raw material for the green

We have prepared a short film to introduce the topic and raise pupils' awareness of the importance of raw materials for landscaping. The film focuses primarily on secondary raw materials. These are obtained by processing (recycling) discarded material (in the film example, old tyres). In this way, they help to avoid waste and conserve finite natural resources. The film can be followed by a short discussion with the class on the importance of raw materials for landscaping.

In-depth: Video clip on secondary raw materials from used tyres

Valuable secondary raw materials can be recovered by recycling used tyres.
In addition to high-quality rubber granules, this also includes the steel and textile fibres contained in tyres. But other used car parts must also be disposed of properly and recycled in the best possible way. The more recycled secondary raw materials are returned to the material cycle, the better it is for our environment.

NEW LIFE Partner Estato Environmental Service handles the complete workshop disposal of around 600 branches of the A.T.U Group.

Teamwork: Secondary raw materials and renewable raw materials in landscaping

Teamwork: Secondary raw materials and renewable raw materials in landscaping

A large number of natural, renewable raw materials are used in landscaping. However, non-renewable raw materials with limited availability are also used for the maintenance, installation and design of gardens and green spaces. These include, for example, peat-based soils and substrates, the use of which releases considerable amounts of CO2.

Wherever possible, natural, renewable raw materials and secondary raw materials obtained from the environmentally friendly recycling of waste or waste products should be used in landscaping and gardening with a focus on sustainability and environmental protection.

What are the naturally renewable raw materials used in landscaping? Which sustainable secondary raw materials can be used in landscaping? In small groups, find as many sustainable raw materials as possible and then collate your results.

Educational game: City, country, raw material

After the pupils have dealt with the topic of raw materials, the knowledge they have acquired so far can be deepened and expanded in a playful way. We have prepared a variation of the well-known game CITY, COUNTRY, RIVER for this purpose.

First choose a letter from the alphabet. Then the pupils have 60 seconds to write down a term with the corresponding initial letter for each category if possible. The pupil receives 10 points for each correct term. If a pupil is the only one in the class to write down a term, they receive 20 points. The game can be played individually or in small groups.

Learning quiz: 5 questions about raw materials

In a quiz, pupils can once again engage with the topic of raw materials in a fun way. There are four alternative answers to each question, at least one of which must be correct. The quiz can be played with the whole class in small groups or by each pupil individually. The correct solution should be discussed briefly afterwards.

Click on the graphic to display the resolution in which the correct answer(s) is/are highlighted. Click again to display the next question. Note: The quiz questions can of course also be printed out.

Excursus: Tyres as a source of raw materials

Passenger and commercial vehicle tyres are an important basis for transport, logistics and individual mobility. Around 538 tonnes of used tyres were generated in Germany in 2021. The more of these tyres are recycled into new raw materials in an environmentally friendly way, the better for people, the economy and the environment. 

Especially as used tyres are a rich and versatile source of raw materials. Tyre recycling can be used to recover valuable secondary raw materials such as steel, rubber and textile fibres, which can be used to conserve natural resources such as rubber.

Most of the rubber recycled from old tyres is ground into rubber granulate. This can be used to produce a considerable variety of durable, sustainable products for landscaping. Vulcanised recycled rubber can also be used to manufacture new tyres without compromising on quality. And the pyrolysis process can be used to regenerate valuable raw materials for industry, such as pelletised carbon black.
