Kathryn Kellogg

Scraptastic Thursday is Kathryn Kellogg's recurring content series dedicated to cooking with food scraps that would otherwise be thrown away — think carrot tops, citrus rinds, and vegetable stems. She runs it under the hashtag #scraptasticthursday and it has become one of the most recognizable signature segments in her zero-waste content lineup. It connects directly to her broader philosophy of getting the most out of every ingredient you bring home.

Yes — Kathryn Kellogg identifies as a UN Speaker in her own Instagram bio, making her one of a small number of social media creators to have brought a zero-waste message to a United Nations platform. That credential distinguishes her from lifestyle influencers who cover sustainability only at a surface level. It reflects the degree to which her work has crossed over from online content into real-world policy and advocacy spaces.

Kathryn Kellogg is a three-time published author focused on practical sustainable living.

Kathryn Kellogg compiled a popular list of 50 items she no longer purchases as part of her zero-waste lifestyle — covering everything from single-use packaged goods to conventional household products.

It's a concrete, habit-change resource rather than abstract sustainability advice.

Scrappy cooking is Kathryn Kellogg's approach to building meals from the parts of food most people discard — herb stems, stale bread, vegetable peels, and similar scraps. She tags this content with #scrappycooking alongside her plant-based and seasonal recipe posts.

Kathryn Kellogg has addressed the widespread belief that balloons released into the sky simply disappear — pointing out that what goes up must come down, and that balloon debris ends up as litter in oceans and wild habitats where animals can ingest it. She covers it as part of her broader content on hidden and culturally normalized sources of plastic pollution. Her framing tends to resonate because it challenges a celebration tradition most people haven't thought critically about.

She also has partnerships with Narwal Robotics and June's Journey on YouTube.
