Gravity-fed, three-stage attachable filter catches microplastics (e.g., microfibers shed from laundry) before they enter the wastewater.

Balls placed in the laundry machine or dryer capture microfibers shed when washing or drying synthetic fibers.

Unmanned aerial robot detects marine debris (especially fishing gear) in the open ocean for later collection or satellite tagging.

Battery-powered, zero carbon emissions robot uses artificial intelligence to collect floating waste.

Large pipes anchored across rivers catch surface-level debris.

Mesh nets remove debris from stormwater and wastewater.

Ship with saucers uses centripetal force to capture and separate waste into five size classes for later disposal.

Nets with 2.5 cm mesh are suspended from catamarans (12 x10 m) and collect plastic waste up to 4 m deep from bays, estuaries, and coastal regions.

Ship brings waste onboard for manual sorting and mechanical compacting before being carried to land for processing.

Pump in a partially submerged plastic box draws in and catches surface trash.

Solar- and wind-powered ship collects plastic and other debris; sensors detect waste and sonar protects fish and other animals from being collected.

Floating boom couplings span waterways to capture waste and prevent it from traveling further downstream.

Floating barricade carries debris to the riverbank for manual or mechanical collection.

Floating device uses waterway currents to capture and guide litter into the trap before it flows downstream.

C-shaped boom and screens use currents to corral trash.

Automated bucket uses a pump to capture floating debris, including plastic.

Sand is piled on a sheet of fine mesh stretched between two long poles, and the mesh catches plastic and other foreign material while allowing the sand to fall through.

Boat collects oil, microplastics, and other debris using a system of nets and baskets; clean water then flows back into ocean.

Tennis ball containers repurposed into fishing line recycling bins for anglers.

Filter removes microplastics while primarily filtering water for reuse.
