1. Reference and strategic objective
What to do with used candle jars has become an important question because the stability and circular economies revaluate the waste currents under increasing global attention. For candle product companies, the management of used jars is important to demonstrate environmental leadership, reduce costs and increase brand price. This report outlines strategies for permanent candle jar management, with reusing reuse and innovation.
Objectives target cost reduction in raw materials, waste disposal, and operational management. Current used jar volumes are an untapped resource, often landfilled due to poor management. This means lost material value and higher disposal costs for manufacturers, a loyalty opportunity for brands, and process optimization for recyclers. The unit type (manufacturer, retailer, recycler) determines the implementation.
JAR recyclability depends on the material (glass, metal, ceramic) and preparation (wax/label removal). Clain Glass/Metal Jars are usually capside recycles; Ceramic jars are usually not occurred. Common in candles for heat resistance, generally glass, is often rejected by recycles due to its high melting point compared to soda-rim glass. It leads to “Viscycling”.
2. Internal Reuse and Repurposing Strategies
Integrating used jars into operations offers a direct path to circularity. This section details internal reuse methods: refilling, repurposing, and process efficiencies.
2.1. Refilling Programs
Refilling is the most direct internal reuse. It involves collecting, cleaning, and refilling jars with new wax. ReCandle Co. uses ceramic jars designed for reuse, proving viability.CandleXchange offers a return/swap program, giving 30% off for returned containers, incentivizing a closed-loop system.
Rigorous cleaning and sterilization are paramount for refilling. Jars must be thoroughly cleaned of wax, wicks, and labels before sterilization.Pre-cleaning involves freezing to remove wax, using utensils, then washing with soapy water or rubbing alcohol, followed by rinsing.
2.2. Internal Repurposing for Other Products or Uses
Beyond refilling, jars can be internally repurposed for other products or uses, extending their lifecycle and reducing new container needs. Examples:
- Other product containers: Cleaned jars can package non-candle items (bath salts, stationery) or food-grade products with strict sterilization.
- Organizing tools: Jars can store small parts, office supplies, or tools, thus reducing purchasing costs. It can also promote the practice of upcycling jars into pen holders/vases.
- Decorative elements: Cleaned jars can serve as decor in retail/offices, enhancing sustainable brand image.
2.3. Process Efficiencies in Cleaning and Handling
Efficient cleaning/handling are critical for reuse program viability and scalability. Manual cleaning is costly at scale. Industrial cleaning technologies are essential for high-volume processing.
You can leverage advanced cleaning technologies:
- Automated Bottle/Jar Washers: Systems offer automated multi-cycle washes (pre-wash, heated detergent, hot rinse) in stainless steel, with quick-change features for various jar sizes.
- High-Pressure Bottle Washers: Machines use strong clamps and stainless steel for stable washing, integrating feeding, grabbing, flipping, rinsing, and discharging.
- Ultrasonic Cleaners: Systems use high-frequency sound waves to create cavitation bubbles, effectively cleaning glass without harsh chemicals. Frequencies vary for glass types (20-40kHz for plain, 78-200kHz for delicate).
- Automatic Bottle/Jar Washer: Systems offer automatic multi-cycical wash (pre-wash, heated detergent, hot rins) in stainless steel, which features quick-change features for various jar sizes.
- High-pavement bottle washes: Machines use strong clamps and stainless steel for stable washing, integrates feeding, grabbing, flipping, rining and discharging.
- Ultrasonic cleaner: Systems use high -frequency sound waves to create bubbles in the cavity, effectively cleaning glass without rigid chemicals. The frequencies for glass types vary (20–40KHz for plain, 78–200KHz for delicate).
- Automatic Rinsing Machines: Cleaning the shower and providing 300–1200 pieces of cleaning machines with adaptation for blow-dry, hot water, alkaline or detergent stages.
- Steam Cleaning: Industrial Steam cleaner (STI) cleans glass bottles with high pressure steam, remove dirt, residues and microorganisms.
Technology selection depends on contamination (wax, dust), glass types (borosilicate vs. soda-lim), and the amount of production. Some industrial washer process shows 500–76,000 bottles/hors, showing scalability. Some consume 0.5–0.6 liters/glass.
Quality control is important: inspect the jar for damage before sterilization; Test new glass for impurities. It is necessary for GMP, especially for food-grade revival.
3. External Market Engagement and Upcycling Models
External markets and partnerships unlock value from jars not internally reusable. This involves direct sales, collaborative upcycling, and new collection/redistribution models.
3.1. Direct Sales of Empty Jars
Excess or unsuitable jars can be sold directly to businesses/consumers, generating revenue and diverting waste. Options include:
- B2B Sales: Sell cleaned jars to small businesses/artisans for their products (e.g., candles, crafts, storage), tapping into the eco-friendly market.
- B2C Sales: Create a platform for consumers to buy empty jars for personal upcycling, aligning with sustainable demand and fostering community.
3.2. Collaborative Upcycling Initiatives into New Products
Collaborating with external partners transforms used jars into higher-value upcycled products, moving beyond simple recycling.
