Cardboard Grannies Art Exhibition: Transforming Trash into Treasure to Support Hong Kong’s Unsung Heroes
- Written by Media Outreach

Based on NGOs' statistics, Hong Kong has 4,000 to 7,000 cardboard collectors, and most are elderly women. These "Cardboard Grannies" collectively recycle approximately 138 to 159 metric tons of materials daily.
They are spending more hours and more days each week collecting cardboard, and more elderly individuals are entering the field, as they have few other options, according to NGOs' survey.
To spotlight their plight and provide tangible support, The Evangelical Lutheran Church Social Service - Hong Kong (ELCSS - HK) and YWAM Tuen Mun present "Cardboard Grannies Art," a special one-day exhibition featuring meaningful and symbolic artworks by acclaimed Hong Kong artist Go Hung, who transforms cardboard collected by these women into thought-provoking pieces critiquing inequality and waste.
Details of the Exhibition: Date: 7 April 2025 (Mon) Time: 12 PM – 9 PM Venue: M4 Atrium, The Mills, 45 Pak Tin Par St, Tsuen Wan Featured Artist: Go Hung
How It Works: This initiative is built on a sustainable three-part model designed to create immediate and lasting change. First, Fair Pay for Labor: Cardboards used in the artworks were collected directly through the cardboard grannies —ensuring that they are compensated well for their tireless work. Next, Art with Purpose: The collected cardboard is handed over to artist Go Hung, whose socially conscious practice breathes new life into discarded materials. Through his creative vision, the grannies' cardboard is transformed into 25 powerful artworks that challenge perceptions about value, waste, and inequality. Finally, Impact Through Purchase: Every artwork sold at the exhibition will directly benefit the Cardboard Grannies, with the proceeds funding essential support for them, such as food and insurance, to provide them with long-overdue security. By bridging art and activism, this project doesn't just raise awareness—it creates a tangible and environmentally-friendly cycle of empowerment for the elderly recyclers.

"I'm a Collector" "I'm a Collector" was created in response to the hype surrounding "Art Month," where the spotlight often highlights the exclusivity and glamour of art collecting at fairs. In contrast, this work turns attention to the city's elderly "cardboard grannies," who collect cardboard and tin cans to resell, just to make ends meet. Often well past retirement age, these individuals work outdoors year-round, exposed to harsh weather as they push heavy metal carts loaded with their "collections" through back alleys, steep streets, and traffic-heavy roads. The works shine a light on their quiet resilience, documenting a raw, overlooked reality while questioning societal values around labor, dignity, and what it truly means to "collect." | HKD30,000 |
The Coin Series: "1kgdp" "1kgdp" highlights the challenges faced by cardboard grannies during periods of economic instability. Inspired by the drop in street-recycled cardboard prices to HK$0.5 per kilogram in previous years, the design captures the impact of external factors such as China's ban on importing certain types of waste and disruptions in Hong Kong's wastepaper export industry. Each 50-cent coin weighs 1 kilogram and features a large-scale design with a diameter of 62 centimetres. Like its predecessor, it is crafted using three types of paper—cardboard, A4 paper, and newspaper. It symbolizes the ongoing struggles of the cardboard grannies and the precarious nature of their livelihoods. | HKD26,000 |
The Coin Series: "Spare Charge" "Spare Change" reflects the struggles of Hong Kong's cardboard grannies, who collect and sell cardboard as a means of survival. The design draws inspiration from the average price of cardboard in earlier years, when it was sold for HK$0.7 per kilogram. To symbolize this, each edition consists of seven 10-cent coins with a total weight of 1 kilogram. Crafted from materials commonly collected and resold by the grannies—cardboard, A4 paper, and newspaper—the coin serves as both a tribute to their daily efforts and a reflection of how seemingly insignificant contributions play a vital role in sustaining livelihoods. | HKD10,400 |
"So.call Mobility" "So.call Mobility" (a play on "social mobility") features 180 cardboard pillows suspended in six layers. The number 180 symbolizes the maximum days homeless individuals can stay in temporary shelters in Hong Kong, after which they face immense challenges finding housing due to high rents. The increasing gaps between the layers represent the widening wealth gap and diminishing social mobility. | HKD500 each pillow |
"Shelter" "Shelter" draws inspiration from the intricate nests of weaver birds to explore the concept of home. In nature, nests symbolize safety and stability—the desire for which is a universal instinct shared across species. Yet for humans, particularly in Hong Kong, the idea of home is often overshadowed by challenges such as skyrocketing property prices and economic struggles. The nests in this installation are crafted from plastic straps commonly used by cardboard grannies to secure and bundle cardboard. These humble materials, repurposed into intricate forms, highlight the resilience and resourcefulness of those on society's margins. The installation features 14 "Shelters," representing the number of government-recognized temporary shelters available for homeless individuals in Hong Kong. It serves as both a reflection on these physical spaces and a call to confront the city's growing housing crisis. | HKD24,000 |
《同人》 《同人》 is a wordplay based on the Cantonese phrase 同人唔同命. Created for Art Month, this piece mimics paintings sold at auction houses by recreating them directly onto cardboard. Once the painted layer is torn off, it reveals the message "Sold for HK$0.5/kg" to the audience—a powerful commentary on the local and global wealth gap. | HKD4,550-HKD6,550 |
