Concrete, wood, used grease: why sustainability is versatile

Concrete, wood, used grease: why sustainability is versatile

Sustainability is multifaceted. This was the experience of the guests at a public event hosted by the "CSU alpaqkas" sabrina stemplowski and daniel nagl. Three speakers examined the topic from different perspectives, as a press release states.

The first speaker was elisabeth ziegler from LZR, who presented the need for sand and gravel mining and the initiatives of the mining companies to protect species. "We have to build," she stressed. In bavaria alone, 85 tons of sand and gravel were used each year. That’s seven tons per capita. From an ecological point of view, you have to use the material locally and not drive trucks through germany. "Only a regional raw material is a truly sustainable raw material," says ziegler. In this sense, LZR sees gravel pits as "borrowed land" that will be used as higher-value farmland or biotopes once the raw material has been extracted.

Modular timber construction of particular interest for kindergartens

With uwe rothenberger, the material changed from concrete to wood. The expert in modular wood construction at wolf bavaria emphasized its advantages for municipalities. This type of vehicle is particularly interesting for kindergartens, which are needed at short notice. "Construction time is reduced by 75 percent," he said. The low level of construction site traffic and noise should not be underestimated either, she said. Over 90 percent of the buildings can be individually planned and prefabricated in the factory – insulation, flooring, facades and so on. Inclusive. Thanks to sustainable forestry, more wood is currently growing back than is being processed. Not to be underestimated is the good carbon footprint and the fact that wood construction can be completely dismantled without any problems.

Third in the group was hubert zenk of lesch altfettrecycling from central franconia. He explained how every citizen could contribute to the mobility revolution by collecting used grease from private households. In a pilot project in the district of roth and the cities of furth and erlangen, first successes have been achieved.

Collect oil and grease residues and don’t dispose of them down the drain

Zenk and his team have equipped more than 60,000 burgers with containers in which they can collect oil and grease residues from pans and deep fryers – instead of simply disposing of them down the drain, as is usually the case. The full boxes can easily be exchanged for clean and empty holders in specially set up vending machines. "Consumer acceptance is high," says a pleased zenk, who is optimistic that the number will continue to grow. Edible fat and oil are valuable raw materials. Biodiesel can be produced from it almost 1:1.

In the final round, daniel nagl gave the speakers another 30 seconds to convince mayor candidate stefan guntner and council candidate timo markert of their ideas. Their conclusion: great impulses on which to build further, the report concludes.
