According to the Forest Fibre Industry��s 2050 Roadmap, there are continuous plans to reduce the environmental impact of paper production.	Bruce 2024-10-26	0146	Bruce 2024-10-26 11:35
Today, thanks to advancements in treating industrial wastewater, the toxicity of this organic matter has been substantially reduced.	Bruce 2024-10-26	0175	Bruce 2024-10-26 11:34
The wastewater involved in kraft paper production was also historically an environmental issue, releasing considerable amounts of organic material into rivers and lakes.	Bruce 2024-10-26	0129	Bruce 2024-10-26 11:34
As a result, dioxin production has reduced significantly.	Bruce 2024-10-26	0145	Bruce 2024-10-26 11:34
since the 1990s, the use of elemental chlorine in the delignification process was substantially reduced and replaced with ECF (Elemental Chlorine Free) and TCF (Totally Chlorine Free) bleaching processes.	Bruce 2024-10-26	0154	Bruce 2024-10-26 11:34
In the past, chlorine was widely used in the bleaching of wood pulp, especially chemical pulps produced by the kraft process, which produced significant quantities of toxic dioxins.	Bruce 2024-10-26	0143	Bruce 2024-10-26 11:33
This means that hardly any sulfur dioxide (an indirect greenhouse gas) enters the atmosphere.	Bruce 2024-10-26	0165	Bruce 2024-10-26 11:33
Although there are various malodorous emissions as a result of this process, control of these odours is achieved through their collection and burning in a recovery boiler.	Bruce 2024-10-26	0139	Bruce 2024-10-26 11:33
To make kraft paper, the lignin and cellulose in the wood must be separated by cooking it in chemicals such as sodium sulfide.	Bruce 2024-10-26	0140	Bruce 2024-10-26 11:33
In recent years, the manufacture of kraft paper has become considerably more eco-friendly.	Bruce 2024-10-26	0137	Bruce 2024-10-26 11:32
However, in order to determine whether it is sustainable or not, it is important to make the distinction between its manufacture and its after-use.	Bruce 2024-10-26	0134	Bruce 2024-10-26 11:32
Kraft paper is derived predominantly from wood chips, a renewable resource	Bruce 2024-10-26	0149	Bruce 2024-10-26 11:32
Is kraft paper environmentally sustainable?	Bruce 2024-10-26	0141	Bruce 2024-10-26 11:32
However, the qualities that make it eco-friendly also means it will weaken when it makes contact with water and will eventually degrade in the presence of heat, sunlight, and humidity.	Bruce 2024-10-26	0147	Bruce 2024-10-26 11:31
In its natural form, its light brown colour and rough texture is favoured for its earthy, natural associations.	Bruce 2024-10-26	0145	Bruce 2024-10-26 11:31
Today, kraft paper has become a widely used packaging material for a range of goods	Bruce 2024-10-26	0142	Bruce 2024-10-26 11:31
The resulting pulp can then be made into a variety of paper products, including kraft paper.	Bruce 2024-10-26	0153	Bruce 2024-10-26 11:31
Once the pulp is formed, it is then screened to remove larger pieces, before being washed to remove any residual fluids.	Bruce 2024-10-26	0149	Bruce 2024-10-26 11:30
As a result, the pulp is high in cellulose, which is the main component of paper and is naturally structurally resistant.	Bruce 2024-10-26	0146	Bruce 2024-10-26 11:30
This removes a polymer called lignin from the pulp, as lignin binds cellulose fibres together at a microscopic level.	Bruce 2024-10-26	0143	Bruce 2024-10-26 11:30
