Short answer: the zero waste obligation attaches to the building, not to your event. Turkey's Zero Waste Regulation was published in the Official Gazette on 12 July 2019, issue 30829. Article 16 sets out who must obtain a zero waste certificate, and the scope covers the buildings and campuses listed in Annex 1: shopping malls, accommodation facilities with 250 rooms or more, business centres, airports, universities and organised industrial zones. There is no separate zero waste certificate for an event or for the agency running it. If your venue is in scope, you work inside its system. A venue that fails to set up or document that system faces an administrative fine of 173,801 lira in 2026. There is also something new on the table. Since 1 July 2026 the Deposit Return Scheme, known locally as DOA, has been running in all 81 provinces, and every business that sells or serves packaged drinks, hotels and event venues included, sits inside the return chain. Below: which document belongs to whom, what a thousand person event actually weighs in waste, and the clauses to put in your venue contract.
Is zero waste mandatory at events, and who holds the certificate?
The regulation ties the obligation to buildings and campuses rather than to organisations or activities. Article 15 defines four certificate levels: basic, silver, gold and platinum. Article 16 sets the obligation to obtain one. Article 17 fixes validity at five years and requires a renewal application three months before expiry. The scope covers shopping malls, accommodation facilities with 250 rooms or more, business centres and commercial plazas, airports and ports, universities, organised industrial zones and chain retailers. Where a business centre has a single shared management, one certificate is issued in that name, so if your office sits in a plaza the document belongs to building management rather than to you. Reporting continues year round: waste data is declared in January and July, and monthly figures are entered by the 15th of the following month. The penalty sits in Article 20 of Environmental Law 2872. The 2026/1 Communiqué, published in the Official Gazette on 30 December 2025, issue 33123, applied the 25.49 percent revaluation rate from 1 January 2026 and set the fine for failing to establish or document a zero waste management system at 173,801 lira. The venue pays that fine. The party that usually breaks the sorting on show night is production, so put the waste plan into the load in briefing.
How does the deposit return scheme launched on 1 July 2026 affect your event?
DOA stands for packaging with a deposit. The mandatory deposit management system rests on the Packaging Waste Control Regulation published in the Official Gazette on 26 June 2021, issue 31523, and is run by the Turkish Environment Agency. Scope is single use plastic, glass and aluminium beverage containers between 0.1 and 3 litres. Containers larger than 3 litres, dairy packaging and carton drink boxes stay outside. The pilot began in Sakarya in February 2025 at 25 kuruş per container. According to Minister of Environment, Urbanisation and Climate Change Murat Kurum, the scheme reached all 81 provinces and 973 districts on 1 July 2026 with the refund raised to 1 lira per container, and the ministry expects 25 billion containers to be collected each year, worth roughly 30 billion lira to the economy. Two consequences land on event teams. Any business selling or serving packaged drinks must be registered on the deposit information system at dbys.gov.tr and must have appointed a field operator. Hotels, restaurants and cafés, which is where most corporate events happen, collect returned and consumed containers and hand them to that operator. Run the arithmetic: at an 800 guest gala, three bottles of water and soft drinks per head is 2,400 containers, which is 2,400 lira of deposit. If those empties go into mixed waste, the money goes with them.
How much waste does a thousand person event actually produce?
The most widely cited measurement in the sector comes from MeetGreen: a conference attendee generates 1.89 kilograms of waste per day, of which 1.16 kilograms goes straight to landfill. For a thousand people over two days that works out at roughly 3.8 tonnes of waste and 2.3 tonnes of landfill. The weight concentrates in five places: food waste, single use service items, printed material, decor and stand structures, and badges with lanyards. Food is already a heavy line in Turkey. United Nations Environment Programme figures from its Food Waste Index put annual waste per capita in Turkey at 93 kilograms in households, 28 kilograms in food service and 16 kilograms at retail. The national picture has improved, though. In a statement dated 31 March 2026, the Ministry of Environment, Urbanisation and Climate Change reported that the recovery rate under the zero waste programme rose from 13 percent in 2017 to 37.53 percent, that systems are now in place at 217 thousand buildings and campuses, and that 90 million tonnes of waste returned to the economy over eight years, worth about 365 billion lira. The target is 60 percent by 2035 and 70 percent by 2053.
What is ISO 20121, and is it worth having for corporate events?
ISO 20121 is the management system standard for event sustainability. It traces back to the London 2012 preparations. The British Standards Institution published BS 8901 in 2007, and the international version, ISO 20121, was released in the summer of 2012 alongside the Olympic and Paralympic Games. The 2024 revision was timed for Paris 2024. Two changes in that revision speak directly to event agencies. Clause 6.1.2 now asks organisations to weigh climate change, environmental resilience, digital responsibility, human and child rights, mental health and diversity when identifying sustainable development issues. Clause 8.3 gives supply chain management its own home and requires suppliers to provide evidence of sustainability requirements during procurement, while also asking that the process stay workable for small businesses. The certificate is not mandatory in Turkey. It comes up because global client specifications and public tenders ask for it. The sector wide commitment is Net Zero Carbon Events, the initiative hosted by the Joint Meetings Industry Council, whose roadmap was launched at COP27. More than 500 organisations have signed a pledge to halve emissions by 2030 and reach net zero by 2050, working across five areas: venue energy, food and food waste, logistics, smart production and waste management, and travel and accommodation.
Which documents should you ask a venue for?
Five will do. First, the zero waste certificate: ask for the level and the expiry date, because validity runs five years and late renewals are common. Second, the deposit system registration and the name of the appointed field operator, attached to the proposal. Third, for hotels, the sustainable tourism certificate. The programme is run by the Ministry of Culture and Tourism together with the Turkish Tourism Promotion and Development Agency, built on Global Sustainable Tourism Council criteria. A ministry circular dated 26 December 2025 requires facilities holding a Stage 1 certificate to move to Stage 2 once their one year term ends, and four and five star hotels, holiday villages, boutique and special accommodation facilities must present a Stage 3 certificate for tourism operation applications and certificate changes. Stage 2 and Stage 3 documents are valid for three years. Fourth, waste infrastructure: how many separate collection points the venue runs, and whether it issues a weighbridge slip after the event. Fifth, energy: whether the hall draws from the grid, and how many hours the generator will run. Ask these at proposal stage rather than on load in morning.
How do you cut waste at the design stage of decor, stands and print?
Most of the waste is created at the drawing board, not on show day. Three decisions do the heavy lifting. Modularity comes first. Build stages, catwalks and stands from rented modular systems instead of timber cut from scratch for every job, so a dismantled part moves to the next event rather than to a skip. Second, keep dates off the structure. Do not print the event date or the sponsor logo onto the main body; move them to a separate layer or onto the LED screen, and the structure stays reusable. Third, choose the print substrate carefully. PVC banner is single use in practice and hard to recycle, while fire certified textile print folds, washes and hangs again. The same logic runs through collateral. A QR code linked run of show instead of a printed programme, a card badge body, and a lanyard collection box at the exit. Collecting lanyards takes five minutes at the end of the night. After five events the box is full and the sixth event has no lanyard line in the budget.
Which catering and beverage decisions actually move the needle?
Two of them. Water first. Glass carafes and a water station beat lining tables with 0.33 litre plastic bottles, and the effect is direct: fewer containers inside the deposit scheme means both a smaller deposit float and less volume to collect. Where packaged service is unavoidable, outdoors or at a standing cocktail, put the return bin somewhere guests can see it rather than behind the bar. Second, portion planning. Set your guaranteed headcount against a realistic no show rate rather than against the RSVP list, because confirmed attendance and the number of people in the room are never the same at corporate events. Food that never left the kitchen, still sealed and with the cold chain intact, can go to a food bank. Article 40, subparagraph 10 of the Income Tax Law lets businesses record the cost of food donated to associations and foundations engaged in food banking for the poor as an expense, and Article 17/2-b of the Value Added Tax Law exempts that delivery from VAT. The donation has to be documented with an invoice and a delivery note. Buffet food that has already gone out to service does not qualify, and food safety rules are the reason.
How do you produce an environmental scorecard for the event?
You cannot report what you never measured. Collect four numbers on the day: the venue's waste weighbridge slip with the breakdown by type, the count of deposit containers handed to the field operator, generator fuel use plus kilowatt hours drawn from the grid, and where attendees travelled from. With those four in hand your post event report rests on records instead of estimates, which is what gives you leverage in next year's budget conversation. The corporate side is closing in too. Reporting under the Turkish Sustainability Reporting Standards has been mandatory for companies in scope since 1 January 2024, and the standard does not require Scope 3 greenhouse gas disclosure during the first two reporting periods. Once that exemption window closes, event travel, accommodation and supplier emissions land in the report, and starting to collect the data on that day is starting late. Tales Event is based in Istanbul and runs dealer meetings, product launches, openings, gala nights and graduation ceremonies with stage, sound, lighting, LED screen, decor and exhibition stand production under one roof. Share your date, venue and headcount, and we will put the waste, packaging and energy plan on the table alongside the budget.
