The System is Broken

California's $1.5 billion bottle redemption industry exploits workers, wastes resources, and fails communities.

$15

Poverty Wages

Collectors walk 5+ miles daily through trash for just $15 in 6 hours. No benefits. No dignity. No future.

$600M

Wasted Value

40% of bottles never get redeemed. Restaurants dump hundreds weekly while collectors search empty-handed.

ZERO

Zero Power

Collectors have no voice, no organization, no bargaining power. An invisible workforce exploited by a broken system.
