Strategic investment of embodied energy during the architectural planning process

Building industry impacts natural cycles and has potential for optimization. While impairment on nature reached a new dimension already some three centuries ago the building industry started to realize the dependency in the second half of the 20th century. With LCA method all life cycle phases can be monitored and the environmental impact of each can be quantified. The energy consuming and emission generating components in the building context can be distinguished in the groups transport, operation and material. An architect deals with the operational energy and the building substance. With nearly zero (not renewable) energy for operation an ecological building is defined by the building substance. Evaluation of the building substance While the building structure accounts for the highest share of embodied energy and GWP, the facade offers high potential for optimisation. This potential is even higher when considering a long (50-100 years) usage life span; the building structure remains while the (non load-bearing) facade is object to exchange cycles. Findings and their integration into the architectural planning process The city is a depot for resources and we (it involves a variety of professions) need to learn how to organize it. Modularity, light construction, the use of renewable materials and mono materials are also interesting fields which are looked at from a different point of view. They are relevant for all building elements. Although they are not initially invented to reduce the ecological impact of the built environment, they show potential to do so. The facade is the essential parameter for the resource-efficiency of a building as it is exchanged and binds relevant amounts of material. Impact can be made within this element due to its high variation in construction and materialization. The material cycles need to become smaller and the gaps – landfill or downcycling need to be closed. The use of resources will increasingly develop impact on architecture and by that resource efficiency is a successor of energy efficiency

ANALYSIS OF PHYSICOCHEMICAL PROPERTIES AND TERRESTRIAL DYNAMICS OF MECHANICALLY FORMED MICRO-NANO SCALED PARTICLES FROM AGRICULTURAL PLASTIC MULCHES

Release of microplastics (MPs) and nanoplastics (NPs) into agricultural fields is of great concern due to their reported ecotoxicity to organisms that provide beneficial service to the soil such as earthworms, and the potential ability of MPs and NPs to enter the food chain. Most fundamental studies of the fate and transport of plastic particulates in terrestrial environments employ idealized MP materials as models, such as monodisperse polystyrene spheres. In contrast, plastics that reside in agricultural soils consist of polydisperse fragments resulting from degraded films employed in agriculture. There exists a need for more representative materials in fundamental studies of the fate, transport, and ecotoxicity of MPs and NPs in soil ecosystems. The objective of this study was therefore to develop a procedure to produce MPs and NPs from agricultural plastics (a mulch film prepared biodegradable polymer polybutyrate adipate-co-terephthalate (PBAT) and low-density PE [LDPE]), and to characterize the resultant materials. Soaking of PBAT films under cryogenic conditions promoted embrittlement, similar to what occurs through environmental weathering. LDPE and cryogenically treated PBAT underwent mechanical milling followed by sieve fractionation into MP fractions of 840 μm, 250 μm, 106 μm, and 45 μm. The 106 μm fraction was subjected to wet grinding to produce NPs of average particle size 366.0 nm and 389.4 nm for PBAT and LDPE, respectively. A two-parameter Weibull model described the MPs\u27 particle size distributions, while NPs possessed bimodal distributions. Size reduction did not produce any changes in the chemical properties of the plastics, except for slight depolymerization and an increase of crystallinity resulting from cryogenic treatment. This study suggests that MPs form from cutting and high-impact mechanical degradation as would occur during the tillage into soil, and that NPs form from the MP fragments in regions of relative weakness that possess lower molecular weight polymers and crystallinity

Metal recycle and recovery

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The development of techniques for the removal and recovery of metals from industrial effluent taking account of the consequences of the definition of waste in the Basel Convention on transfrontier shipment of waste is reported. The use of fluidised bed cell electrolysis in the recovery of metals from dilute solutions is investigated, and the conditions for recovery optimised. For the first time the application of a novel activated carbon cloth concentrator cell to recover metals from effluent solutions is reported and the conditions for its use optimised. Comparative studies using conventional mesh and plate electrodes, and novel activated carbon cloth electrode for the recovery of cobalt from dilute solution, and copper from three different hydrometallurgical solutions viz (i) Cu/Zn, (ii)Cu/Zn/Fe and (iii) Cu/Zn/Cd containing effluents were carried out. Application of concentrator cell technology including activated carbon cloth and ion exchange resin to the recovery of metals, including precious group metals, from industrial as-supplied samples is reported. Optimisation leads to successful recovery of iridium and palladium from very dilute solutions. The alternative recovery of metal as added-value chemicals is also investigated. The Basel Convention is concerned with transfrontier shipment of waste from developed to developing countries and has produced a need to investigate the leachability of metals in various forms. In this work the leachability of copper and zinc is studied under various conditions that model environmental situations and the results have been used to develop a methodology to determine whether a metal containing material would be subject to a shipment ban under the Convention. As part of the development of the methodology, leaching studies were also carried out on single chemical compounds of copper, zinc, cadmium and lead, and their bioavailability determined
