Newspapers are biodegradable. Newspaper is safe to compost, but it breaks down quite slowly because of its high lignin content.Since newspapers are brown composting material, they need to be offset by green composting material. ... The ink used on today's newspaper is 100 percent non-toxic. This included both black and white and color inks. The ink on newspaper in a compost pile will not hurt.
