GLASS BOTTLES
Where It All Began

Long before sustainability and circular economy practices became bywords in modern business, San Miguel Brewery, one of the country’s oldest enterprises and Southeast Asia’s first brewer, was already employing its returnable glass bottle (RGB) system, which endures as a critical part of its business.

For many decades, SMB’s RGB system has contributed significantly to its bottom line, minimizing costs and reducing required resources through the constant reuse and recycling of glass bottles. Under the system, customers only pay for the contents and a deposit on the bottle when they buy products. Returning the bottles to recover the deposit becomes nearly routine for customers nationwide, allowing the bottles to be brought back to the SMB system where these are washed, sanitized, and reused.

SMB’s glass bottles are designed to go through this cycle 60 times or more. SMB ensures that recycled bottles follow the company’s strict quality standards, which also consider the bottles’ aesthetic value. Visibly worn bottles are sent to SMB’s sister company, SMYPC, for recycling, along with bottles reaching their end-of-life stage. This ensures that all bottles are recycled, and none are wasted.

As glass is perpetually 100% recyclable, the system, in place for most of the company’s 132- year history, has afforded both SMB and the environment incalculable benefits in lower costs, decreased extraction of new raw materials and minimized solid waste in landfills. This has also helped to ingrain a zero-waste mindset in our culture.

In many ways, glass bottle retrieval and recycling is also crucial for SMC’s spirits business, Ginebra San Miguel Inc. The preference for glass bottles as packaging material stems from its inherent characteristic to preserve the quality of our products for a longer period of time as well as its high reusability and recyclability.

With an expansive network of third-party bottle suppliers that spans the whole Philippine archipelago, used bottles are retrieved, sorted and pre-washed prior to delivery at GSMI’s various bottling facilities. Upon acceptance, these bottles undergo stringent quality inspections and further cleaning prior to filling with Ginebra’s products. Bottles deemed unfit for reuse are transformed into glass cullet, which are then sold to SMYPC to be recycled into new bottles once again.

This highly efficient system of retrieval and reuse keeps GSMI’s bottle in circulation for as long as possible to effectively reduce its requirement for brand new bottles by 72% in 2022. But more importantly, aside from minimizing production costs, it helps prevents the accumulation of solid waste and reduces the use of natural resources needed to produce new bottles. This program not only supports cost management for the company but also plays a crucial role in reducing glass bottle manufacturers’ dependence on new materials, leading to a substantial positive impact on the environment.

Furthermore, both SMB and GSMI also maintain their own internal bottle retrieval programs to encourage employees to contribute to the effort to minimize the number of uncollected bottles not in their systems.

SMYPC plays a crucial role in the success of both SMB’s and GSMI’s circular economy programs. With its business model for discarded glass containers and cullets, SMYPC’s raw materials, fuel, power consumption, and waste generation are significantly reduced.
