コーヒー焙煎プロセスは、二酸化炭素や窒素酸化物などのガスの排出を通じて環境汚染に寄与します。従来の焙煎機は時代遅れの設計によりこれらの問題を悪化させます。現代的な解決策と業界全体の戦略が、これらの影響を低減することを目指しています。
コーヒー業界は環境影響を最小限に抑えるため持続可能な開発を重視しており、焙煎は管理されない場合にリスクを伴うバリューチェーン上の重要な段階として特定されています。焙煎中、燃料の燃焼により熱が発生し、二酸化炭素 (CO₂)、窒素酸化物 (NOx)、一酸化炭素 (CO)、および微細粒子状物質が空気中に放出されます。天然ガスや液化石油ガス (LPG) などの燃料を使用した排気ガスの後燃焼処理は、追加の揮発性化合物と二次排出物を生成します。不十分な処理システムは総排出量を増大させ、地域的な大気汚染とより広範な環境負荷を引き起こします。
