Boats are racing, waste competition (Türkiye) [2026]

Country: Türkiye

Site: Fethiye Municipality

Target: Tourists and visitors, Local communities and residents, Practitioners

Short Description

A competition by Fethiye Municipality and the Fethiye Chamber of Maritime Trade ensured proper separation of boat waste to prevent pollution, reduce microplastics, and support the circular economy.

Waste was collected daily, recorded per boat, and included wet waste, packaging waste, and waste oils.

A total of 156 boats competed in three categories—Daily, Private, and Charter Tour Boats. Rankings were based on passenger capacity and per capita waste: high packaging (kg/person/day), low wet waste (kg/person/day), and regular oil delivery. Some information about environment awareness was also displayed (ex: one litre of waste oil can pollute one million litres of seawater and five million litres of drinking water)

Goals

• To prevent recyclable waste from becoming general waste

• To encourage greater attention to this issue through incentive-based awards among boat operators and employees

• To protect marine ecosystems against climate change, especially macro/microplastics and waste oils

Reproducibility/lessons learnt

• In line with sustainability principles, such practices are considered a necessity rather than a choice.

• Recycling contributes to energy and oil savings and protects natural resources such as trees, sand, soda ash...

• Local authorities were highlighted as facilitators in preventing solid and liquid waste from entering marine environments.

Give invasive aquatic plants a new life (Japan) [2026]

Country: Japan

Site: Yanmar Sunset Marina

Target: Tourists and visitors, Local communities and residents, Staff

Short Description

At Lake Biwa, invasive aquatic plants have rapidly spread, harming the shoreline and making boat navigation unsafe. To address this issue, the marina removes these plants and then turn them into compost through a dedicated system. With the compost, vegetables and cotton are cultivated, and the cotton is used for the staff uniforms. By using aquatic plants that were previously incinerated as waste, the marina reduces both waste generation and emissions. However, the resource circulation remains small compared to the large amount of invasive aquatic plants.

Goals

• Demonstration of a business model utilizing an organic resource circulation system based on aquatic plant recycling.

• Realization of the “Lake Biwa Eco‑Cycle Zone” through the expansion of a resource‑circulation network in collaboration with local governments, businesses, and residents.
  
  

Reproducibility/lessons learnt

• The resource‑circulation process should be easy to understand by visualizing it clearly

• The Blue Flag certification can be used as a symbol to communicate environmental goals and policies, and to demonstrate ongoing commitment.

• Working with local governments, businesses, and residents can help to raise environmental awareness
