'''Sampah makanan''' adalah [[makanan]] yang terbuang dan menjadi [[sampah]]. Definisi '''sampah''' dapat dilihat dari berbagai sisi sehingga berbagai lembaga dan organisasi dapat menggunakan definisi yang berbeda-beda mengenai sampah makanan ataupun makanan yang terbuang.<ref>{{Cite book|title= Food waste to animal feed|last= Westendorf|first= Michael L.

== Penyebab ==
Sampah makanan dapat terbentuk sejak dalam proses produksinya di [[lahan pertanian]], [[pasca panen]], [[pengolahan makanan|pengolahannya]], hingga konsumsinya.
=== Produksi makanan ===
Di negara berkembang dengan pertanian komersial dan industri yang maju, sampah makanan dapat terbentuk pada tahap produksinya.<ref name="kantor3">{{Cite journal | last = Kantor | first = Linda | coauthors = Kathryn Lipton, Alden Manchester and Victor Oliveira |date=January–April 1997 | title = Estimating and Addressing America’s Food Losses | url = http://www.ers.usda.gov/Publications/FoodReview/Jan1997/Jan97a.pdf |format=PDF| accessdate = 2009-08-14}}</ref> Sedangkan negara dengan [[pertanian subsisten]] yang dominan, sampah makanan yang terbentuk tidak dapat diketahui jumlahnya secara pasti namun diperkirakan tidak signifikan karena outputnya yang jauh lebih kecil dibandingkan pertanian industri. Meski demikian, besarnya kehilangan hasil panen ketika dilakukan pemanenan hingga transportasi dapat mencapai angka yang cukup tinggi di negara yang pertaniannya masih relatif kurang maju.<ref>

=== Pengolahan makanan ===
Setelah pasca panen, kualitas [[penyimpanan makanan]] berperan penting dalam mencegah terbuangnya makanan.<ref name="hall">{{Cite book|title = Handling and storage of food grains in tropical and subtropical areas|last = Hall|first = David Wylie|year = 1970|publisher = Food & Agriculture Organisation|isbn = 978-92-5-100854-6|url = http://books.google.com/?id=SHALVB8In4YC&lpg=PA1&dq=machinery%20and%20food%20losses&pg=PA1#v=onepage&q=|accessdate = 2009-08-21}}</ref> Penyimpanan makanan menjadi relatif sulit di negara tropis basah karena [[temperatur]] dan [[kelembaban]] tinggi merupakan kondisi yang ideal bagi hama dan mikroorganisme untuk berkembang biak.<ref name="foa1">{{cite web | title = Loss and waste: Do we really know what is involved? | url = http://www.fao.org/DOCREP/004/AC301E/AC301e02.htm | publisher = [[Food and Agriculture Organization]] | accessdate = 2009-08-23}}</ref> Kehilangan secara kualitatif seperti edibilitas, nilai kalori, nilai nutrisi, dan sebagainya lebih sulit dinilai ketimbang kehilangan secara kuantitas.<ref name="hall" /><ref>{{cite journal |last = Lacey

Beberapa tahapan proses tidak dapat menghindari terbentuknya sampah makanan karena alasan keamanan dan ingin mencapai bentuk atau kualitas tertentu dari makanan yang akan diproduksi.<ref name="oreo1" /><ref name="kantor3" /><ref>{{cite book|title=Food industry and the environment in the European Union: practical issues and cost implications|last=Dalzell|first=Janet M.|year=2000|publisher=Springer|isbn=0-8342-1719-8|page=300|url=http://books.google.com/?id=3j-xV3i5iY4C&pg=PA300&lpg=PA300&q=|accessdate=2009-08-29}}</ref><ref>{{cite journal |authorlink=International Finance Corporation |year=2007 |title=Environmental, Health and Safety Guidelines for Meat Processing |page = 2 |url=http://www.ifc.org/ifcext/enviro.nsf/AttachmentsByTitle/gui_EHSGuidelines2007_MeatProcessing/$FILE/Final+-+Meat+Processing.pdf |format=PDF|accessdate=2009-08-29}}</ref><ref>{{cite web | title = Specific hygiene rules for food of animal origin | url = http://europa.eu/legislation_summaries/food_safety/veterinary_checks_and_food_hygiene/f84002_en.htm | publisher = [[Europa (web portal)|Europa]] | year = 2009 | accessdate = 2009-08-29}}</ref>

[[Toko]] dapat membuang sejumlah besar makanan, biasanya yang telah melewati [[usia simpan]]nya atau yang telah kedaluwarsa. Tergantung kebijakan toko, makanan dapat dikembalikan ke produsen atau ke fasilitas daur ulang. Toko juga terkadang mengalami masalah manajemen penyimpanan produk sehingga harus membuang sebagian. Jika yang harus dibuang adalah makanan yang masih layak dikonsumsi, toko dapat menyumbangkannya ke [[lembaga amal]]. Kebijakan pemilik toko, terutama dalam hal pemesanan juga berpengaruh dalam menentukan seberapa besar makanan yang terbuang dari sisi produksi. Jika toko tidak mampu menyerap hasil panen [[petani]] atau produsen sesuai dengan perjanjian, maka kemungkinan besar petani atau produsen akan membuang hasil panennya tersebut.<ref>{{Cite book|title = Waste: Uncovering the Global Food Scandal: The True Cost of What the Global Food Industry Throws Away|first = Tristram|last = Stuart|publisher = Penguin|year = 2009|isbn = 0-14-103634-6}}</ref>
== Penanganan ==
=== Tempat pembuangan akhir ===
Tempat pembuangan akhir merupakan solusi termudah dan termurah dalam menangani sampah makanan, namun menyebabkan masalah lingkungan yang tertinggi diantaranya menjadi sarang serangga penyebar penyakit, [[bau]], dapat mencemari [[air tanah]], dan mampu menciptakan [[gas rumah kaca]] akibat [[dekomposisi]] bahan organik dari sampah makanan. Di Inggris, sampah makanan menyumbang 19% total sampah yang dibuang ke TPA (Tempat Pembuangan Akhir).<ref name="From Farm to Fridge to Garbage Can">[http://well.blogs.nytimes.com/2010/11/01/from-farm-to-fridge-to-garbage-can/?ref=science From Farm to Fridge to Garbage Can]. // The New York Times, 1.11.2010</ref> Demi mencegah hal ini, seluruh restoran di kota New York dilarang membuang sampah makanan ke TPA (Tempat Pembuangan Akhir).<ref>{{cite news|title=Turning Food Waste Into Fuel Takes Gumption And Trillions Of Bacteria|url=http://www.npr.org/templates/transcript/transcript.php?storyId=287310897|agency=NPR|author=Joel Rose|date=2014-03-11}}</ref>
=== Pakan hewan ===
Berbagai hewan dapat memakan makanan sisa yang dibuang manusia, tidak terkecuali hewan peliharaan dan hewan ternak.<ref>{{cite web|url=http://blog.mcmurrayhatchery.com/2011/10/04/feeding-your-chickens-table%C2%A0scraps/ |title=Feeding Your Chickens Table Scraps | McMurray Hatchery Blog |publisher=Blog.mcmurrayhatchery.com |date=2011-10-04 |accessdate=2012-10-21}}</ref> Meski demikian, tidak semua sisa makanan manusia cocok untuk hewan.<ref>{{cite web|author=Chicken Feed: How to Feed Chickens |url=http://keeping-chickens.me.uk/getting-started/chicken-feed |title=Feeding Chickens: What to feed chickens to keep them healthy | Keeping Chickens: A Beginners Guide |publisher=Keeping Chickens |accessdate=2012-10-21}}</ref> Ayam dan unggas lainnya secara tradisional dilepaskan di area lahan yang baru dipanen dan bangunan penggilingan biji-bijian untuk mencari sesuatu yang dapat dimakan.
=== Kompos ===
Sampah makanan dapat terdegradasi dengan mudah sehingga dapat di[[kompos]]kan untuk dijadikan [[pupuk]].<ref>[http://www.antiochne.edu/ssj/CompostingCaseStudy.pdf Vermicomposting study for reducing food waste]</ref><ref>[http://www.swlf.ait.ac.th/UpdData/Presentations/Thai/8%20Vermicomposting%20of%20Food%20Wastes.pdf Vermicomposting for reducing food waste]</ref><ref>[http://www.redwormcomposting.com/worm-farming/restaurant-food-waste-vermicomposting/ Vermicomposting for reducing food waste in restaurants]</ref>
=== Daur ulang ===
Limbah [[minyak goreng]] sisa restoran umumnya ada dalam jumlah besar, terutama yang menjalankan proses memasak secara ''deep frying''. Limbah tersebut tidak dapat digunakan kembali secara langsung, namun dapat diolah untuk dijadikan [[biodiesel]] dan [[sabun]],<ref>{{cite web | publisher=CDM - Executive Board | title=Production of biodiesel based on waste oils and/or waste fats from biogenic origin for use as fuel | url=http://www.mct.gov.br/upd_blob/0016/16059.pdf |format=PDF| accessdate=2007-09-05}}</ref> juga [[lipid]] untuk nutrisi tambahan pakan ternak, [[kosmetik]], dan [[deterjen]].<ref>Murphy, Denis J.
