Cows??????

Cows and the approach to the utilization of resources found in the waste SOCIALIST APPROACH: You have two cows …. You decide to give one to your neighbor ! COMMUNIST APPROACH: You have two cows …. The State takes both and gives you some milk ! BUREAUCRATIC APPROACH: You have two cows …. The State takes both, shoots one, milks the other, and then throws the milk away ! FRENCH APPROACH: You have two cows …. You go on strike, organize a riot, and block the roads because you want to have three cows and feel that you rightfully deserve them ! AMERICAN APPROACH: You have two cows …. You sell one, and force the other to produce the milk of four cows. Later, you hire a consultant to analyze why your only cow suddenly has dropped dead ! You decide to sue your vetenirarian !! GERMAN APPROACH: You have two cows …. You re-engineer them so they eat once a month, and milk themselves ! ITALIAN APPROACH: You have two cows … but you don't know where they are. You decide to have lunch ! JAPANESE APPROACH: You have two cows …. You re-design them to miniature cows that can produce 20 times the milk of bigger cows ! AUSTRALIAN APPROACH: You have two cows …. Business seems pretty good. You close the office and go for a few beers to celebrate ! GRI APPROACH: You have two cows …. You clean them up to make them attractive to each other. They produce multiple baby cows that you can milk for many years !!!

Summary Traditionally, in most countries gypsum and plasterboard waste has been landfilled mixed with other waste fractions Some countries, mainly European, have found out that this is not the way to go for many reasons: –Landfills are running out of space –Gypsum waste is particularly problematic to landfill –Landfilling gypsum waste does not utilize the ressources found in the waste Gypsum Recycling International has successfully developed and for more than 10 years operated a technology that fully recycle gypsum plasterboard waste and utilize all the ressources found in the gypsum waste Both fractions: –the gypsum and –the paper from the gypsum waste, is recycled for a 100% recycling rate

C&D and gypsum waste in Landfills Around the Globe C&D waste is the largest or second largest waste fraction in most landfills around the globe Gypsum plasterboard/ wallboard waste is in most countries one of the 3 largest fractions of the C&D waste landfilled The fraction is growing due to the continued increase in the manufacturing and consumption of plasterboard (particularly in the Middle East) As gypsum waste cannot be incenerated (due to the generation of sulphur dioxide, a toxic gas) landfilling is the most typical disposal route in countries where recycling of gypsum does not occur  Worldwide it is estimated that 15 million tons of gypsum waste are landfilled, but as gypsum waste is eternally recycable this does not have to be the case !

Gypsum waste is problematic in the landfills Landfilling gypsum waste make the landfills fill up faster -> landfills reach their full capacity -> very dificult to extent or build new landfills anywhere in the world Gypsum waste generates hydrogen sulphide gas (H2S) in the landfills if the gypsum waste is not landfilled in a separate cell where no organic waste is present H2S is lethal in large concentrations, and deaths cases have occured in landfills due to H2S As a consequence: –Some states in the US and Canada have implemented a ban on landfilling of gypsum waste –the EU has implemented regulations requiring that if landfilled, the gypsum waste is landfilled in a separate cell where no organic waste is present Landfilling the gypsum waste lead to that the resources found in the gypsum waste are literally wasted instead of being utilized

Benefits of Recycling Gypsum Waste Gypsum is eternally recycable without loss of quality, due tot the chemical nature of the material Recycling generates local green jobs; landfilling does not require a lot of labor, recycling does Recycling of gypsum waste in many countries lowers the import of expensive gypsum raw materials from abroad Recycling helps the local gypsum industry to obtain raw materials at a lower cost For each ton of gypsum waste that is being recycled instead of landfilled 0,2 tons of CO2 emissions will be saved The Scandinavian and Benelux countries have achieved recycling rates of gypsum waste ranging from 50-85% and the recycled gypsum generated account for 25% of the gypsum raw materials used by the local gypsum plants

Successful policy instruments: Policy Instruments that do NOT work Low or no landfill tax Soft requirements like –“best efforts” –“to the greatest extent possible” Regulations without enforcement; –No inspections –No tough financial penalties “Social contracts” with the public, the waste sector or construction sector  Why ?  Because the waste industry is a „for profit“ business and the operator with the lowest costs will prevail (also if this is caused by that the operator does not follow the regulations)  Consequently recycling will only happen if  it makes economic sense to do it  the authorities assure that operators not recycling will be penalized

Successful Policy Instruments A high Landfill tax ; –All studies of the recycling rates and landfill tax in various countries have found that a very positive correlation between high landfill tax and high recycling rates exist –The landfill tax in Scandinavia and Benelux is averagely 80 USD / ton High landfill prices; If government controlled landfills, the landfills should price in the lifetime cost of landfilling, not just the direct cost. –The average landfill price in Scandinavia and Benelux is around 200 USD/T A high incineration price and tax – to avoid C&D waste is sent to incineration, when it can be recycled instead Required on site segregation (into containers for the different waste fractions) at building sites above a certain size of a certain minimum percentage of the waste generated (typically 60-70%). Requirement for obtaining building permits that a waste plan describing how 70% recycling of the waste made during the building project can be achieved, coupled with requirement to report on the volume of waste sent to recycling after the project has been completed Ban on landfilling of specific waste types, that are recyclable Strong culture of inspections, enforcement and penalties towards the construction and especially the waste sector
