The transition to a circular economy in the built environment is key to achieving a resource-effective society. The built environment can be made more circular by applying circular building components. The purpose of this paper is to present a design tool that can support industry in developing circular building components.

The tool was developed and tested in five steps. In Step 1, the authors analysed existing circular design frameworks to identify gaps and develop requirements for the design tool (Step 2). In Step 3, the authors derived circular design parameters and options from existing frameworks. In Step 4, the authors combined and specified these to develop the “circular building components generator” (CBC-generator). In Step 5, the CBC-generator was applied in the development of an exemplary component: the circular kitchen and tested in a student workshop.

The CBC-generator is a three-tiered design tool, consisting of a technical, industrial and business model generator. These generators are “parameter based”; they consist of a parameter-option matrix and design canvasses. Different variants for circular components can be synthesised by filling the canvasses through systematically “mixing and matching” design options.

The developed tool does not yet support establishing causal links between “parameter-options” and identification of the most circular design variant.

The CBC-generator provides an important step to support the building industry in developing and implementing circular building components in the built environment.

Whilst existing tools and frameworks are not comprehensive, nor specifically developed for designing circular building components, the CBC-generator successfully supports the integral design of circular building components. First, it provides all the design parameters which should be considered; second, it provides extensive design options per parameter; and third, it supports systematic synthesis of design options to a cohesive and comprehensive circular design.

Examines the tenth published year of the ITCRR. Runs the whole gamut of textile innovation, research and testing, some of which investigates hitherto untouched aspects. Subjects discussed include cotton fabric processing, asbestos substitutes, textile adjuncts to cardiovascular surgery, wet textile processes, hand evaluation, nanotechnology, thermoplastic composites, robotic ironing, protective clothing (agricultural and industrial), ecological aspects of fibre properties – to name but a few! There would appear to be no limit to the future potential for textile applications.

Problem solving courts are a result of the therapeutic jurisprudence movement. Drug treatment courts (DTCs), for instance, aim to divert substance using offenders away from the criminal justice system (CJS) to (drug) treatment services. DTCs are associated with reduced criminal offending and substance use. Psychosocial outcomes of DTCs, such as employment, health and family relations, received only little attention. The paper aims to discuss these issues.

This paper focuses on the outcomes regarding substance use and psychosocial variables of a Belgian DTC situated in the Ghent region, which were investigated by a naturalistic evaluation study with a pre- post-design using judicial files.

The results show that Ghent DTC clients were diverted to drug treatment and financial counselling services. Next the Ghent DTC produced beneficial outcomes regarding employment. Contrary to criminal offending (De Keulenaer and Thomaes, 2013), substance use was not significantly reduced in the Ghent DTC sample. Yet more compliance with opioid maintenance treatment was observed. Information on more client centred outcomes such as health and social relations was lacking, precluding a full outcome measurement of psychosocial variables.

Future DTC studies should address more client centreed outcomes by gathering information through DTC clients and treatment services instead of solely relying on judicial data sources. In addition, DTCs should develop a clear and uniform registration system regarding these outcomes.

Since the therapeutic jurisprudence movement continues to expand, discussion regarding the roles and tasks of the CJS as well as treatment and counselling services is vital. Each actor should maintain its own role and task, regarding monitoring and substantive work, to insure a “problem solving approach” that is in line with the recovery philosophy.
