Energy audits for the Wiesbauer Holding AG according to the Austrian energy efficiency law for buildings, process and mobility were conducted. Focus for these energy audits was laid on the identification of optimization measures to increase renewable energy on the one hand and reduce the energy demand on the other hand. Energy saving potentials and dynamic amortisation for the identified measures were calculated, technical descriptions made, and potential public funding possibilities identified. The interaction of processes was shown and possibilities to measure the impact were identified. The following representative sites of Wiesbauer Holding AG were selected for conducting energy audits:
At the site in Oberndorf an energy audit according to the Austrian energy efficiency law for buildings was conducted. Focus for this energy audit was laid on the identification of optimization measures to increase renewable energy on the one hand and reduce the energy demand on the other hand. Energy saving potentials and dynamic amortisation for the measures were calculated, technical descriptions made and potential public funding possibilities identified. The interaction of processes was shown and possibilities to measure the impact were identified.
To reduce the energy demand for the heating supply, an industrial heat pump was installed. The waste heat of the cooling machine and eco-electricity are used for efficient and CO2 neutral process heat production.
With the installed waste heat recovery an integrated heat concepts was implemented with the focus on waste heat utilization in lowest temperature range. During planning a special focus was at the loads in low temperature ranges. In many cases there is low demand for low temperature waste heat resulting in low efficiency of waste heat recovery systems. In cooling and especially in freezing there are many consumers.
The existing engines were retrofitted with synchronous engines and frequency converters. In comparison to fixed speed control the variable control needs less electricity. Via a speed controlled drive system the utilization rate in variable load ranges is maximized and thus energy saved.
Enhancement of the energy transformer operation via adaptation of steam providers to operation and production times. Until now the steam boiler was running constantly independent from operation and production times.
Professional waste and wastewater treatment as well as local energy supply is a huge challenge in Tanzania. To solve this problem the technical requirements for the production of biogas and its economic feasibility was evaluated. Companies from the sisal processing, fattening and slaughtering as well as a food processing company was evaluated.
The focus was on the material and energy flows as well as waste quality and possible energy production systems and their economic feasibility. One of the reports was published by UNIDO.
Replacement of the existing CHPP as supplier for process heat and for self-sustained energy supply. Optimization of the heat utilization of the CHPP
Increasing the energy efficiency is one of the most important measures for energy savings and lowering of CO2 emissions. For public recognition of these measures the WEKA Industrie Medien in cooperation with klimaaktiv organized the energy efficiency conference. Klimaaktiv is the climate protection initiative of the ministry for environment in Austria (BMLFUW) and an instrument to foster the energy transition.
At the conference 48 best practice projects were awarded for the successful implementation of energy efficiency measures. Minister for environment, Andrä Rupprechter, was awarding the energy efficient companies and their consulters. kleinkraft is thanks for the consulter award.
Technical and economic feasibility study for international Waste-to-Energy projects. The results of the study were summed up in the following conference article
Carbon dioxide (CO2) is mainly responsible for the global climate change and its catastrophic effects. But, this greenhouse gas has not only disadvantages. As provider of carbon, CO2 can be used as raw material for the production of fuels or chemicals. Thus, produced CO2 is used instead of emitted to the atmosphere. Dependent from purity, the exhaust gas can be used directly or after a cleaning step. In our process the CO2 is afterwards used to produce chemicals.
