The client is a waste company owned by Odense Municipality, which collects and receives many types of waste, including garden/park waste from the public recycling sites in Odense Municipality and sewage sludge from the wastewater company VandCenter Syd A/S.

In Odense Municipality's waste plan "Your waste - our resource", it has been decided that the municipality must increase recycling in order to meet recycling targets laid down in the government's resource strategy from 2013. The present invitation to tender is part of the implementation of this plan and the contract tendered for the same reason sets requirements for the quality of the compost produced.

An amendment to the Environmental Protection Act in 2022 has meant that from 1.7.2023 onwards, the Contracting Entity must tender for the composting task in accordance with the Public Procurement Act and with the opportunity to bid for the task itself. Odense Renovation A/S offers a public contract for composting garden/park waste and sludge.

The contracting entity tenders a public contract for composting garden/park waste and sludge. It is estimated that the total amount to be received is approximately 30,000 tonnes of garden/park waste and approximately 10,000 tonnes of dewatered sludge per calendar year. The estimates are subject to uncertainty and do not guarantee the quantities indicated.

Sludge means dewatered sewage sludge that the Client receives from wastewater treatment from the treatment plants operated by VandCenter Syd A/S.

Sludge composting is a process in which dewatered sludge is mixed with garden/park waste and straw. The process is described in more detail in Annex A and its underlying annexes. The sludge compost produced is called Biocompost and must have a purity that, in accordance with current legislation, makes it suitable for application to agricultural land.

The offer also includes clean composting. Pure composting means equivalent composting, but without the addition of dewatered sludge and straw. Clean composting will only occur to the extent that there is excess amounts of garden/park waste compared to the amount to be used in Biocompost production.

The economic operator must dispose of the compost produced.
