Rubbish facts

This page contains filthy rubbish facts ranging from microplastics to cigarette butts.

Littering is one of the greatest human-induced problems that threaten both people and nature. Littering is caused by many things, such as litter left in the environment by people, inadequate urban runoff treatment and insufficient waste bins.  

What effects does littering have?  

Littering has harmful effects on both ecosystems and people. Marine fauna – particularly mammals, birds and fish – can get caught in waste that has ended up in the sea. Similarly, eating rubbish can be harmful to a wide range of organisms. Plastic waste causes the death of one million seabirds and a hundred thousand marine mammals worldwide every year (Finnish Environment Institute 2022).  

Litter also affects the overall living comfort, and its removal results in significant costs for society. In 2023, the City of Helsinki spent nearly 14 million euros on keeping public areas clean. The May Day cleanup in Helsinki cost over 160,000 euros.  

Most rubbish is made of plastic

Plastic is everywhere, from food and cosmetics packaging materials to phone cases, clothes and interior textiles. Plastic waste accounts for the majority of all litter that ends up in the environment. Plastics persist in the environment for a long time, gradually becoming brittle and breaking down into smaller pieces and particles. The amount of microplastics, i.e. small plastic particles, in the environment is constantly increasing, and it is practically impossible to remove.  

Microplastics are less than five millimetres in size. These microscopic pieces of plastic have been found inside fish, shellfish, crustaceans and even in deep-sea organisms on the ocean floor.   

Microplastics also end up in the human body, especially through drinking water. People are exposed to microplastics daily through food, indoor and outdoor air (e.g. street dust), and skin, but the extent of exposure and its potential effects on health are not yet fully known (Finnish Environment Institute 2022).  

Did you know that over 90 per cent of seabirds have consumed plastic? In the 1960s, this figure was less than five per cent

Cigarette butts are the most common form of litter in the world  

Billions of cigarette butts end up in nature every year in Finland alone. It takes years for them to break down. Cigarette butts contain plastic and numerous substances that are harmful to organisms and will end up in the soil and water during decomposition. 

Did you know this about cigarette butts?  

  • Cigarette butts are the most common form of plastic waste in the world, including on the shores of Finland.  
  • Cigarette butts contain e.g. arsenic, lead, nicotine, cadmium, copper and formaldehyde. These harmful substances are absorbed into the environment from cigarette butts discarded on the ground and in water.  
  • It can take up to 10 years for a cigarette butt to fully decompose, and in nature it will break down into tiny microplastics.  
  • Moreover, gritting sand cannot be reused the following winter because it contains so much litter – mainly cigarette butts.

How does rubbish end up in nature and the oceans?

Littering is caused by many things: litter left in the environment by people, inadequate urban runoff treatment, sewage overflow, fly-tipping, storage and disposal of snow removed from the streets, insufficient waste bins and litter carried by wind from construction and demolition sites.   

Cities, in particular, have extensive drainage infrastructure for urban runoff. Urban runoff refers to rainwater and meltwater accumulated in built areas. In practice, a drainage inlet on a street leads water through open ditches and/or runoff drainage networks to the nearest body of water and, in some areas, to the sea.   

However, because the drainage inlets do not have specific filters for debris, rubbish ends up in water bodies without processing. Particularly during heavy rainfall and snowmelt, large amounts of rubbish accumulated in parks, on streets and in snowbanks can quickly migrate to the sea and other bodies of water.  

Many people also discard cigarette butts in storm drains. The annual Mahanpuruja muovista (‘Stomach ache due to plastic’) campaign reminds us that urban runoff is usually directed into the nearest body of water largely untreated.

How much does littering cost?

In 2023, the cost of maintaining public areas in Helsinki was almost 14 million euros. More than 4 million euros was spent on cleaning the parks in 2023. Cleaning up after May Day alone costs the City of Helsinki around 160,000 euros.   

The cost of maintaining water areas (such as?) exceeded 400,000 euros in 2023, and cleaning stormwater drains cost Helsinki over 300,000 euros.  

Littering also incurs indirect costs, as it can cause e.g. health hazards for humans and animals.   

How littering is controlled 

In Finland, the national implementation of the EU Single-Use Plastics (SUP) Directive was carried out through amendments to the Waste Act and associated regulations that entered into force at the beginning of 2023. The Directive is aimed at reducing plastic pollution in the environment, especially on seashores, promoting a circular economy and harmonising product regulation in the EU internal market. 

Finland’s Green Deal on plastic packets is also part of the SUP Directive. The aim of this agreement is to ambitiously and permanently reduce the numbers of single-use plastic packets.  

The City of Helsinki is implementing the SUP Directive in two different EU-funded projects. The aim of these projects is to reduce plastic and plastic litter in Helsinki. 

The PlastLife project (link) promotes the circular economy of plastics. The BaltiPlast Interreg project is aimed at reducing the amount of plastic pollution released into nature by identifying, testing and implementing measures for influencing littering.  

The amendment to the EU Packaging and Packaging Waste Directive (EU 2015/720) requires Member States to take measures to reduce consumption of plastic carrier bags. In Finland, the Ministry of the Environment and the Finnish Commerce Federation have drawn up an agreement to reduce the consumption of lightweight plastic carrier bags to less than 40 per person per year by the end of 2025.
