The Environmental Impact of Soy Wax Candles

Candles have been a part of human history for centuries, providing light, warmth, and a sense of ambiance. In recent years, as the world has become more environmentally conscious, there's been a surge in the popularity of soy wax candles. But just how sustainable is soy wax, and what kind of environmental impact does it have? Let's dive deep into this topic.

1. What is Soy Wax?

Soy wax is a vegetable-based wax made from the oil of soybeans. After harvesting, the beans are cleaned, cracked, de-hulled, and rolled into flakes. The oil is then extracted from the flakes and hydrogenated, a process in which the fatty acids are converted into a solid form at room temperature. The result is the soy wax we use in candles.

2. Environmental Benefits of Soy Wax:

  • Renewable Source: Unlike paraffin wax, which is derived from petroleum, soy wax is a renewable source. Soybeans are grown annually, ensuring a consistent and sustainable supply.

  • Biodegradable: Soy wax is natural and biodegradable. It doesn't produce harmful byproducts when it's burned or when it's disposed of, making it a more environmentally friendly choice.

  • Less Soot: Candles made from soy wax tend to produce less soot than those made from paraffin. Less soot means better indoor air quality and less staining on walls and ceilings.

  • Longer Burning Time: Soy wax burns at a cooler temperature, which can result in a longer burning time compared to paraffin wax candles. This can mean buying fewer candles over time and thus reducing consumption and waste.

3. Concerns Regarding Soy Wax:

  • Land Use & Deforestation: Large-scale soy farming can lead to deforestation and other land use changes. While much of the world's soy is used for animal feed, it's essential to source soy wax from suppliers who prioritize sustainable farming practices.

  • Pesticides & GMOs: Most commercially grown soybeans are genetically modified to resist pests and herbicides. This can lead to an increased use of chemicals, which can harm the environment. When purchasing soy wax candles, looking for non-GMO certifications can be a way to mitigate this concern.

  • Processing & Energy Consumption: The process of extracting soy oil and hydrogenating it to produce wax consumes energy. While it may be less than the energy used to refine petroleum into paraffin wax, it's still an environmental consideration.

4. Making a Sustainable Choice:

If you're leaning towards choosing soy wax candles for their environmental benefits, consider the following tips:

  • Buy Local: Reduce the carbon footprint associated with transportation by supporting local soy candle producers.

  • Check Certifications: Look for candles that have certifications for using non-GMO and sustainably grown soybeans.

  • Reuse & Recycle: Once your candle has burned down, consider reusing the container or recycling it, further reducing waste.


Soy wax candles undoubtedly offer several environmental benefits over their paraffin counterparts. They're derived from a renewable source, produce fewer pollutants when burned, and are biodegradable. However, like all products, they come with their set of environmental concerns. By being aware of these and making informed purchasing decisions, you can enjoy the ambiance of a candlelit room and know you're making a choice that's kinder to our planet.
