Biodegradable Substances that can be completely broken down into their basic constituents, for example, water and carbon dioxide, by natural processes. The term is usually misleading when applied to plastic because it can only be degraded under very specific temperature and pressure conditions, and also often leaves behind additives. DOES »BIO«DEGRADABLE PLASTIC EXIST?

Bisphenol A chemical compound, also known as a hormone disruptor. There are various bisphenols. The best-known is bisphenol A, which is found in many plastics and coating varnishes. The substance enters the body with food or through the skin, where it has a similar effect to the hormone estrogen. It interferes with the development of the sexual organs and many other bodily processes. HOW CAN I KNOW WHAT’S IN IT?

Carbon dioxide CO2

Carbon Chemical element with the symbol C. Without carbon, there would be no life on earth: It is found in all the large molecules that make up living things, and thus also in every plant. When this life dies, the carbon ultimately remains – whether in the form of CO2 after decomposition by microbes, in the soil, in water, or after millions of years as oil, coal, or gas.

Climate Temperature and precipitation over a long period of time. Not to be confused with weather, even though there are similarities. The earth’s climate stands in a complex relationship with many processes; recently, humans have begun to change the climate through the massive production of greenhouse gases. This is mainly due to the use of coal, oil, and gas.

CO2 Abbreviation for the gas carbon dioxide, which makes up 0.03% of the air we breathe. Living beings exhale it, plants absorb it and, with the help of light energy, convert it into sugar and ultimately, for example, into cellulose. A lot of CO2 is emitted when coal, oil, or gas are burned. It then acts as a greenhouse gas in the atmosphere.

CO2 equivalent In addition to carbon dioxide, other greenhouse gases such as methane also damage the climate – but to a different extent. Methane remains in the atmosphere for less time than CO2, but heats up the climate much more during this short period. In order to compare greenhouse gases, the effect of CO2 is used as a benchmark. The harmfulness to the climate of the other gases is converted into what are known as CO2 equivalents. This allows us to state total greenhouse gas emissions.

Conventional farming All farms that are not officially certified as organic. In contrast to organic or ecological farming, synthetic fertilizers and pesticides are allowed and antibiotics are less regulated in animal husbandry. Conventional farming is very diverse – there are small farms, large farms, ones that rely heavily on technology, and many others that do not.

Recycling Process in which used products or waste are made useful again. Most packaging is hard to recycle because it is made up of many different components that are almost impossible to separate. Plastic recycling is difficult: The quality of the raw material decreases and needs to be improved by using additives. It often results in inferior products. WHY IS PLASTIC RECYCLING NOT A SOLUTION?

Recycling codes Can be found on packaging. Number 1 to 7 are plastics. The labeling is used to facilitate the recycling of certain substances. WHAT ARE THE MAIN TYPES OF PLASTIC?
