Anthropogenic Carbon Stock Dynamics of Pulp and Paper Products in Germany

摘要: espanolconsumer behavior;industrial ecology;material flow analysis (MFA);modeling;product lifetime;waste management EnglishCarbon-based materials (CBMs) for energetic and material purposes combine biogenic anthropogenic carbon cycles. In the latter, numerous manufactured products with various in-use lifespans accumulate as stocks. Understanding behavior of these stocks is an important requirement to estimate not only future waste amounts, source secondary raw materials, but also impacts effects in emissions management. Previous models have estimated stock changes; however, a lack research perceived. Moreover, studies follow lifespan estimation approaches, such decay functions, which do coincide observed consumption treatment patterns. first part this article, we present stock-flow model analyze inter-relationships between flows from processes considering consumer perspective, where dynamics are completely described. second part, study pulp paper industry Germany under scenario approach behavior, development, 2010 2040. The provided coherent results, industrial data estimating 33.9 million metric tons stocks, equivalent 410 kilograms per person. Consumption capita were identified most significant variables building. Model simulations show sustained growth next 30 years, increase emissions. But combination recycling reuse mechanisms patterns, environmental reduced
