1. Introduction
The maritime industry is the backbone of global trade, transporting over 90% of the world’s goods and supporting millions of jobs. However, this vital sector faces a growing environmental crisis: ship-generated waste. Every year, commercial vessels produce 10–12 million tons of garbage, including plastics, food waste, oily sludge, and hazardous materials. Without proper management, this waste ends up in our oceans, threatening marine ecosystems and human health.
1.1 The Scale of the Problem
Modern ships generate multiple waste streams:
- Organic waste (30–40% of total waste on cruise ships) from galleys and restaurants.
- Plastics and packaging (20–30%), including single-use bottles and fishing gear.
- Operational waste like oily rags and bilge sludge (15–25%).
- Hazardous materials such as batteries and medical waste (5–10%).
On a two-week voyage, a single cruise ship can produce 8–10 tons of waste, while cargo vessels accumulate 1–2 tons weekly. Traditional disposal methods—such as incineration or offshore dumping—are increasingly restricted due to environmental regulations and public scrutiny.
1.2 The Solution: Marine Garbage Baling Machines
To address these challenges, leading shipping companies are adopting marine garbage baling machines—hydraulic systems that compress waste into compact, sealed bales. These machines:
✔ Reduce storage space by 90%, freeing up room for cargo or fuel.
✔ Ensure MARPOL compliance with traceable, audit-ready bales.
✔ Cut disposal costs by 40% through efficient port-handling.
2. Challenges of Marine Waste Management
The management of waste generated by ships during navigation faces multiple complex challenges, involving multiple dimensions such as environment, regulations, operations and costs. With the increasingly stringent global environmental regulations and the improvement of public environmental awareness, traditional waste disposal methods can no longer meet the needs of the modern shipping industry, and may even bring serious legal and financial risks.
2.1 Diverse types of waste, difficult to handle
Ship waste is not only huge in quantity, but also complex in composition, mainly including:
- Organic waste (such as food scraps, kitchen waste), accounting for 30-40% of the total cruise waste, is easy to rot and produce odor and bacteria, posing a threat to the health of crew members and ship hygiene.
- Plastics and packaging materials (such as bottles, packaging bags, fishing nets), accounting for 20-30%, are the main sources of marine microplastic pollution and need to be strictly classified to comply with the prohibition regulations of MARPOL Annex V.
- Operational waste (such as oily rags, engine room sludge), accounting for 15-25%, may contain toxic chemicals, and improper handling will cause marine pollution.
- Hazardous waste (such as batteries, medical waste, chemicals), accounting for 5-10%, requires special treatment to avoid environmental damage.
2.2 Limitations of traditional treatment methods
Currently, the garbage treatment methods commonly used by ships have significant defects:
- Incineration: Although it can reduce the volume of garbage, it will produce harmful gases (such as dioxins) and is prohibited by some ports (such as some ports in the European Union).
- Temporary storage: Uncompressed garbage takes up a lot of space, especially on long-distance voyages, which may cause storage areas to be full and increase the risk of cross-contamination.
- Direct discharge: Although MARPOL allows the discharge of some non-plastic garbage in specific sea areas, mis-discharge or illegal discharge may still result in high fines (such as a bulk carrier was fined $500,000 for discharging oily garbage in 2023).
2.3 High cost of violations
- Legal risks: According to IMO data, there were more than 1,200 MARPOL Annex V violations in the world in 2022, with an average fine of more than $20,000.
- Operational disruption: Failure of port state control (PSC) inspections may lead to ship detention, for example, a container ship was stranded in Singapore for 3 days due to discrepancies in the garbage record book, resulting in a loss of US$150,000.
- Damage to brand reputation: Environmental scandals may lead to customer loss, such as a cruise company’s improper garbage handling was exposed on social media, resulting in a 12% drop in bookings the following year.
2.4 Space and logistics constraints
Ship space is limited, especially for cargo ships and fishing boats:
- 10 tons of uncompressed garbage takes up about 25m³ of space (equivalent to 2 standard container spaces), which can be reduced to 2.5m³ after processing by marine garbage baling machines.
- Some remote routes (such as the Arctic route) lack port reception facilities, forcing ships to carry garbage for a long time, increasing the risk of decay and leakage.
- These challenges highlight the urgency of ship garbage management, and marine garbage baling machines are becoming a key technology for the industry to break through difficulties through compression, standardization and traceability solutions.
3. Technology Deep Dive of Marine Garbage Baling Machine
3.1 Core Structure
The core structure of the modern marine garbage baling machines adopts industrial-grade design standards and mainly includes two key systems:

3.2 Workflow
The workflow of the marine garbage baling machine can be divided into four standardized stages:
Feeding stage
- The operator feeds the classified garbage into the feed port
- The feed port is equipped with a safety grating to prevent misoperation
- The maximum feeding size can reach 800×600mm
Compression stage
- The hydraulic system starts, and the compression plate advances at a speed of 10- 15mm/s
- The compression process lasts for 2-3 cycles
- The system automatically detects the compression density and stops after reaching the set value
Bundling stage
- The automatic bundling device starts
- High-strength galvanized steel belt (width ≥12mm) is used
- Each bag of garbage is bundled 3-4 times to ensure transportation safety
Storage stage
- The bundled garbage bag is automatically pushed out
- The standard bag size is 800×600×500mm
