Parchment paper, also known as baking paper, is a cellulose-based paper that has been processed to achieve non-stickiness, grease resistance, and heat resistance. It is commonly used in baking and cooking as a disposable non-stick paper. Parchment paper is coated with silicone, which gives it its non-stick and heat-resistant properties. Some parchment papers may also have coatings such as PFAS (per- and polyfluoroalkyl substances) for non-stick properties, which can pose potential health risks. While silicone is generally considered safe for food contact, there are concerns about its potential to leach toxins, similar to plastic. To avoid the use of plastic in parchment paper, individuals can opt for brands that explicitly state their product is PFAS-free or choose uncoated parchment paper made from 100% wood pulp.

Parchment paper is coated with silicone, a synthetic polymer made from silicon, oxygen, carbon, and hydrogen
Parchment paper, also known as baking paper, is a thin, non-stick, heat-resistant paper commonly used in cooking and baking. It is made from wood pulp or vegetable fibre called cellulose, which is processed to obtain properties such as non-stickiness, grease resistance, and heat resistance. Parchment paper is coated with silicone, a synthetic polymer made from silicon, oxygen, carbon, and hydrogen, along with other petrochemical-derived plasticizers. This coating enhances its non-stick and heat-resistant qualities, making it ideal for various kitchen applications, such as lining baking trays and pans, wrapping meat or fish, and creating paper envelopes for cooking 'en papillote'.
The silicone coating on parchment paper is generally considered safe for food contact. It is stable at high cooking temperatures and does not leach chemicals, according to some sources. However, other sources express concerns about potential silicone toxins and suggest that it may leach toxins in a similar way to plastic. This has led to a preference for silicone-free alternatives, such as Silpat silicone baking mats, among some consumers.
Parchment paper is available in bleached or unbleached varieties. The super-white or bleached version is treated with chlorine to remove its natural brown colour, making it less environmentally friendly than the unbleached option. Brown parchment paper is biodegradable and can be composted, whereas white parchment paper is more challenging to break down and should be recycled.
While parchment paper is a convenient and functional tool in the kitchen, it contributes to waste due to its single-use nature. Reusable alternatives, such as silicone baking mats, can be preferred to reduce environmental impact. Additionally, it is important to be mindful of potential health risks associated with certain coatings, such as PFAS (per- and polyfluoroalkyl substances), found in some parchment papers for enhanced non-stick properties.
Overall, parchment paper's silicone coating, derived from silicon, oxygen, carbon, and hydrogen, plays a significant role in its functionality, particularly in cooking and baking applications. However, health and environmental considerations have prompted discussions about the potential drawbacks of this coating and the exploration of alternative options.

PFAS, or per- and polyfluoroalkyl substances, are sometimes used as an alternative coating for non-stick properties
Parchment paper is a super-thin baking paper made from vegetable fibre called cellulose with a slippery non-stick surface. The non-stick surface is achieved by coating the paper with food-safe silicone. However, some parchment papers may have alternative coatings, such as PFAS (per- and polyfluoroalkyl substances), which provide non-stick properties. PFAS are synthetic chemicals that have been used in various consumer products since the 1940s or 1950s. They are known for their ability to resist grease, oil, water, and heat. PFAS have a strong carbon-fluorine bond, which makes them stable and resistant to degradation.
PFAS are used in a wide range of industries, including aerospace, automotive, construction, electronics, and food processing. They can be found in cookware, food packaging, and food processing equipment. PFAS are also used to keep food from sticking to packaging and cookware, making them desirable for non-stick applications. However, PFAS have been linked to potential health risks and negative environmental impacts. Due to these concerns, the FDA has taken steps to limit the use of PFAS in food contact applications and is working to reduce dietary exposure to PFAS.
When using parchment paper, it is important to check whether it contains PFAS. Some brands may explicitly state that their parchment paper is PFAS-free. By choosing PFAS-free options and following the manufacturer's instructions for use and disposal, consumers can minimize potential health and environmental risks associated with PFAS exposure. It is worth noting that even PFAS-free parchment paper may have other chemical treatments, so it is always advisable to follow the manufacturer's guidelines and dispose of it properly.
While PFAS provides non-stick properties, its potential health and environmental impacts have raised concerns. As a result, there is a growing trend to replace PFAS with alternative substances or fluorine-free options. This shift is driven by the recognition of the harmful effects of PFAS on human health and the environment, particularly the persistence of PFAS in the environment and the accumulation in the bodies of humans and other species. The widespread use of PFAS has led to increasing levels of contamination in the air, water, and soil, making it essential to explore safer alternatives.

PFAS can pose health risks, so look for brands that explicitly state their parchment paper is PFAS-free
Parchment paper is a super-thin baking paper made from vegetable fibre called cellulose with a slippery non-stick surface. The non-stick surface of parchment paper is usually coated with food-safe silicone, which is stable at high cooking temperatures and does not leach chemicals. However, some parchment papers may have alternative coatings, such as PFAS (per- and polyfluoroalkyl substances), which provide non-stick properties. PFAS are man-made chemicals that can accumulate over time in humans and the environment. They are known as 'forever chemicals' due to their persistence.
PFAS have been linked to adverse health outcomes in current scientific research. Exposure to certain PFAS may lead to reproductive issues, such as decreased fertility or increased blood pressure in pregnant women. PFAS exposure can also cause developmental effects or delays in children, including low birth weight, accelerated puberty, bone variations, or behavioural changes. Additionally, it increases the risk of certain cancers, impacts the immune system's ability to fight infections, and can lead to liver damage, thyroid disease, and obesity.
Therefore, when purchasing parchment paper, it is advisable to look for brands that explicitly state their product is PFAS-free. While PFAS-free parchment paper is a safer option, it is still important to follow the manufacturer's instructions for use and disposal to minimise potential health and environmental risks.
It is worth noting that even if a specific brand of parchment paper does not contain PFAS, other sources of PFAS exposure may be present in daily life. PFAS can be found in drinking water, soil, air, food, and materials in our homes or workplaces. Some people may have higher exposures due to their occupations or proximity to PFAS-producing facilities.

Parchment paper is not eco-friendly due to its single-use nature and the bleaching process for white paper
Parchment paper, also known as baking paper, is a type of paper that has been coated with silicone. It is commonly used in cooking and baking as it is non-stick, heat-resistant, and water-resistant. While it is a more sustainable alternative to some kitchen products, such as wax paper, it is not an environmentally friendly choice due to its single-use nature and the bleaching process for white paper.
The single-use nature of parchment paper contributes to its high environmental footprint. Many people use it once and then throw it away, which creates a lot of waste. This is especially true for those who use parchment paper for multiple purposes, such as lining baking trays, pans, and cake pans, as well as wrapping or covering meat or fish. Even though parchment paper can technically be reused multiple times, it will eventually lose its non-stick properties, leading to more waste.
There are more eco-friendly alternatives to parchment paper that can be used in the kitchen. For example, silicone baking mats are made from food-grade silicone, non-stick, reusable, and often dishwasher-safe. Another alternative is to simply use oil to grease baking pans or trays, preventing food from sticking.
In addition to its single-use nature, the bleaching process for white parchment paper also raises environmental concerns. Bleached parchment paper is treated with chlorine to produce a gleaming white color, while unbleached parchment paper is untreated and totally chlorine-free. Some people prefer to use unbleached parchment paper to limit the number of chemicals in their kitchens, even though there are no known studies that prove bleached parchment to be a health risk.
Overall, while parchment paper has various convenient uses in the kitchen, its single-use nature and the bleaching process for white paper make it less eco-friendly than other alternatives. To reduce waste and environmental impact, it is recommended to opt for reusable options or unbleached parchment paper, which is more environmentally friendly.

Brown parchment paper is biodegradable and can be composted, while white parchment paper should be recycled
Parchment paper is coated with a thin layer of silicon, which makes it heat-resistant and non-stick. It is often used in cooking. While parchment paper is biodegradable, not all types are suitable for composting. Brown parchment paper is generally biodegradable and can be composted, whereas white parchment paper is not compostable and should be recycled.
Brown parchment paper that is unbleached and unwaxed can be included in a compost pile. It is typically made from natural materials and coatings. However, it is important to check the packaging for specific instructions on how to dispose of it. To aid the decomposition process, the paper can be cut into smaller pieces, allowing microbes easier access to the fibres and speeding up decomposition.
White parchment paper, on the other hand, usually contains non-biodegradable materials, making it challenging to compost at home. It is recommended to recycle this type of parchment paper. However, it is important to note that used parchment paper should not be placed in regular recycling bins due to potential food contamination. Instead, the box that the parchment paper comes in can be recycled.
Some concerns have been raised about the potential presence of PFAS chemicals in parchment paper. PFAS, or per- and polyfluoroalkyl substances, have been linked to potential health and environmental risks. If you are concerned about PFAS, look for brands that explicitly state their parchment paper is PFAS-free, and always follow the manufacturer's instructions for disposal to minimise potential impacts.
Additionally, there are concerns about the use of chlorine in bleaching white parchment paper. There is a possibility that dioxins may leach into compost if the paper was bleached with chlorine. As a result, unbleached parchment paper is sometimes recommended for composting. However, it is unclear if all white parchment paper is still bleached using chlorine, and specific brands may use alternative methods.
