Littering

Littering is the dropping or abandonment of waste in public spaces such as streets, beaches, riverbanks, parks and natural areas, instead of disposing of it correctly. It is an environmental, social and economic problem that is largely driven by single-use packaging and plastics consumed on the go.

Littering does more than spoil the landscape: it pollutes soil and water, harms wildlife, and creates significant clean-up costs for local authorities. Because the items involved are small and scattered (cigarette butts, wrappers, cans, bottles), they are also harder and more expensive to collect than concentrated waste.

Definition and legal basis

In Spain, Law 7/2022 on waste and contaminated soil for a circular economy addresses the abandonment of waste in the environment and sets specific obligations for producers and consumers. Littering differs from other forms of dumping because it consists mainly of small, dispersed items generated through everyday consumption: cigarette butts, packaging, bags, wrappers and cans.

Main causes of littering

• Irresponsible behaviour: low environmental awareness and a perception that dropping litter goes unpunished.
• High consumption of single-use plastics: bottles, straws, cups and wrappers designed to be discarded quickly.
• Insufficient collection infrastructure: too few bins or containers in busy areas.
• Mass events and tourism: festivals, beaches and sporting gatherings generate large volumes of litter in a short time.

Most common littered items

• Cigarette butts, consistently the single most common item on European beaches (around a fifth of all collected litter, according to the European Environment Agency).
• Lightweight packaging: cans, plastic bottles and wrappers.
• Plastic bags abandoned on beaches and in rivers.
• Paper and cardboard in streets and parks.
• Chewing gum stuck to pavements.

Environmental impacts

• Marine pollution: the majority of marine litter (estimated at around 80%) originates on land and reaches the sea via rivers, wind and drains. Much of it ends up as marine litter.
• Harm to wildlife: birds, fish and mammals can ingest plastics or become entangled in them.
• Chemical contamination: cigarette butts release nicotine and heavy metals into soil and water.
• Landscape degradation: affects tourism and quality of life.

Economic and social impacts

• High urban cleaning costs for municipalities (estimated in the hundreds of millions of euros a year across Spain).
• Loss of value in natural and tourist areas.
• Social friction caused by the perception of neglect and dirtiness.

Applicable rules

• Law 7/2022 on waste and contaminated soil: applies Extended Producer Responsibility (EPR) so that producers help finance litter clean-up, and provides for penalties for abandoning waste.
• Single-Use Plastics Directive (EU) 2019/904: requires producers of tobacco filters, packaging and plastic cups to cover the cost of cleaning up their products.
• Regional and municipal rules: local ordinances that fine the dropping of waste (for example, cigarette butts on beaches).

Prevention and reduction strategies

• Education and awareness: public campaigns and environmental education in schools.
• Adequate infrastructure: more accessible bins and dedicated collection on beaches and in tourist areas.
• Economic incentives: deposit-return schemes (DRS) and rewards for responsible behaviour.
• Legal measures: fines for abandonment and producer responsibility for clean-up costs.
• Technology: sensors in smart bins and citizen-reporting apps that geolocate litter hotspots.

Relationship with the circular economy

Littering is the antithesis of the circular economy, because abandoned waste never enters any recovery cycle. Tackling it means recovering materials, avoiding waste and reducing environmental impact, which is also the goal of waste prevention.

A key lever in Spain is the deposit-return scheme (DRS) for beverage containers. After Spain failed to meet the EU separate-collection target for single-use plastic bottles (it reached only about 41% in 2023, below the 77% target), Royal Decree 1055/2022 made a mandatory DRS necessary; its national rollout has since been postponed, with full implementation now expected by 2029. Measures like DRS, cigarette-butt recycling and packaging recovery, together with the Spanish Circular Economy Strategy 2030, can turn a problem of abandonment into an opportunity for circularity.
