Secure Every Lid. Cleaner neighborhoods start here.
Helping you solve ESG challenges
Secure Every Lid.
Cleaner neighborhoods start here.
A simply elegant, proprietary and patent-pending passive closure system that helps waste companies prevent windblown litter, recycling spoilage, and improve their ESG scores - one closed lid at a time.
The problem
Wind opens lids. Litter escapes. Communities notice.
Windblown litter from unsecured cart lids is one of the most visible — and avoidable — sources of neighborhood litter. It creates cleanup costs, recycling spoilage, and customer complaints that fall on waste companies and municipalities to resolve during customers' normal use.
The solution
A passive closure that works every time the lid closes.
Green Lock is a proprietary, patent-pending magnetic closure system that installs on compatible carts and passively secures the lid against wind — with no batteries, no electronics, and no change to how residents or collection crews use the cart.
How Green Lock works
Automatic protection every time the lid closes.
Two compact magnetic modules on the front of the lid align with low-profile steel plates on the cart rim. The connection helps resist wind uplift, then releases through normal opening and collection movement.
Install
A low-profile system is fitted to compatible carts in roughly 30 seconds.
Close
The magnetic connection engages passively whenever the customer closes the lid.
Collect
The cart remains familiar to residents and designed for normal collection service.
Product targets vary by cart geometry, installation, weather, and use. Performance should be confirmed for each organization's carts and operating conditions.
One small closure. Multiple enterprise outcomes.
Less litter
Keep more material inside the cart and out of streets, parks, and waterways.
Lower costs
Reduce the conditions that create spoiled recyclables and litter cleanups.
Fewer complaints
Prevent a visible curbside problem before it becomes a customer-service issue.
Stronger ESG
Turn an environmental promise into visible action communities can see at the curb.
Own litter prevention - not just litter cleanup.
Waste companies already invest in sustainability, recycling, customer service, and municipal partnerships. Green Lock connects those priorities at the most visible point in the system: the curb.

Impact at a glance
Small per-cart gains become measurable community impact.
An illustrative planning model shows how quickly litter prevention can scale - while a fast installation and long service life keep the cost side of the equation low.
The quick ROI lens
One passive system. Several avoidable costs.
Every prevented cleanup, spoiled recyclable load, complaint response, and route intervention strengthens the return - before municipal goodwill and sustainability value are counted.
